    BACKGROUND: A rise in tongue pressure coincides with an increase in the suprahyoid muscles activity. OBJECTIVES: The aim was to investigate the effects of holding a weighted plastic bottle on tongue pressure and the suprahyoid muscles activity. METHODS: Eighteen participants (8 men and 10 women; mean age 42 ± 16 years) participated in this study. All participants had no history of speech, language, hearing, or swallowing disorders and no tooth loss, and they did not require dentures. Healthy participants held gauzes connected with a plastic bottle with increasing resistive loads of 0 g, 250 g, 500 g, and 750 g, between their palate and tongue. The maximum tongue pressure and average tongue pressure were measured during a 5-second hold. The average tongue pressure was defined as the mean tongue-pressure data in each task. The suprahyoid muscles activity was measured using the electromyogram (EMG). The root mean square of the EMG signals measured while lifting different loads and while performing the head lifting exercises were compared. All variables were examined using the Friedman's test and Wilcoxon signed-rank test. RESULTS: The maximum tongue pressure (p < .05) and average tongue pressure values (p < .05) increased gradually in the anterior-median region with increasing resistive loads, and the root mean square amplitudes for 250 g, 500 g, and 750 g were not significant compared to head lifting exercises. CONCLUSION: These results indicated that Plastic bottle holding could be a potential strength-training tool for the tongue and the suprahyoid muscles.

    We examined whether the number of teeth could be a surrogate marker for metabolic syndrome (MetS) risk in cross-section. A total of 3771 individuals from the general urban Japanese population (1690 men, 2081 women; mean age 67.1 ± 11.0 years) participated in this study. Participants were diagnosed with MetS with three or more components hypertension, hyperglycemia, lipid metabolism abnormality, and abnormal abdominal girth. Questionnaires were administered to determine the number of teeth, smoking status, drinking status, and past illnesses. To clarify the relationships between the number of teeth and the presence of MetS components, we divided subjects into two groups: those with less than 20 residual teeth and those with 20 or more, then statistical analyses (Mantel-Haenszel tests and logistic regression analysis) were performed. MetS were higher for those with ≤19 teeth than those with ≥20 teeth when examining all participants and women-only groups. Hyperglycemia, low HDL cholesterol, high triglycerides, and diagnosis with MetS were all significantly higher in the ≤19 teeth group for both sexes combined and for women. These results suggest that less than 20 teeth may be a surrogate marker for MetS risk, but further studies on gender differences and pathological background are needed.

    PURPOSE: The purpose of this study was to investigate the effects of tongue-strengthening exercise (TSE) on tongue strength and effortful swallowing pressure in young healthy adults. METHOD: Thirteen young healthy volunteers (six men, seven women; M age = 20.5 ± 0.5 years) performed 8 weeks of isometric TSE 3 days per week. A tongue pressure measurement device was used to measure maximum isometric tongue pressure (MITP) and conduct the TSE, and a tactile sensor system attached to the hard palate was used to measure effortful swallowing pressure. MITP and effortful swallowing pressure were measured at baseline, after 4 and 8 weeks of training, and at 4 and 8 weeks after the last training session to examine the detraining effects. RESULTS: The results indicated that both MITP and effortful swallowing pressure increased significantly from baseline to 8 weeks after training. Although the improved MITP significantly decreased at 4 and 8 weeks after training cessation, no detraining effect was observed for effortful swallowing pressure. CONCLUSIONS: TSE is an effective method for increasing tongue pressure in wide tongue-palate contact areas during effortful swallow. The effortful swallowing pressure gained with TSE appears to be maintained for at least eight nontraining weeks.

    BACKGROUND: It has been widely recognized that mastication behaviors are related to the health of the whole body and to lifestyle-related diseases. However, many studies were based on subjective questionnaires or were limited to small-scale research in the laboratory due to the lack of a device for measuring mastication behaviors during the daily meal objectively. Recently, a small wearable masticatory counter device, called bitescan (Sharp Co), for measuring masticatory behavior was developed. This wearable device is designed to assess objective masticatory behavior by being worn on the ear in daily life. OBJECTIVE: This study aimed to investigate the relation between mastication behaviors in the laboratory and in daily meals and to clarify the difference in mastication behaviors between those with metabolic syndrome (MetS) and those without (non-MetS) measured using a wearable device. METHODS: A total of 99 healthy volunteers (50 men and 49 women, mean age 36.4 [SD 11.7] years) participated in this study. The mastication behaviors (ie, number of chews and bites, number of chews per bite, and chewing rate) were measured using a wearable ear-hung device. Mastication behaviors while eating a rice ball (100 g) in the laboratory and during usual meals for an entire day were monitored, and the daily energy intake was calculated. Participants' abdominal circumference, fasting glucose concentration, blood pressure, and serum lipids were also measured. Mastication behaviors in the laboratory and during meals for 1 entire day were compared. The participants were divided into 2 groups using the Japanese criteria for MetS (positive/negative for MetS or each MetS component), and mastication behaviors were compared. RESULTS: Mastication behaviors in the laboratory and during daily meals were significantly correlated (number of chews r=0.36; P<.001; number of bites r=0.49; P<.001; number of chews per bite r=0.33; P=.001; and chewing rate r=0.51; P<.001). Although a positive correlation was observed between the number of chews during the 1-day meals and energy intake (r=0.26, P=.009), the number of chews per calorie ingested was negatively correlated with energy intake (r=-0.32, P=.002). Of the 99 participants, 8 fit the criteria for MetS and 14 for pre-MetS. The number of chews and bites for a rice ball in the pre-MetS(+) group was significantly lower than the pre-MetS(-) group (P=.02 and P=.04, respectively). Additionally, scores for the positive abdominal circumference and hypertension subgroups were also less than the counterpart groups (P=.004 and P=.01 for chews, P=.006 and P=.02 for bites, respectively). The number of chews and bites for an entire day in the hypertension subgroup were significantly lower than in the other groups (P=.02 and P=.006). Furthermore, the positive abdominal circumference and hypertension subgroups showed lower numbers of chews per calorie ingested for 1-day meals (P=.03 and P=.02, respectively). CONCLUSIONS: These results suggest a relationship between masticatory behaviors in the laboratory and those during daily meals and that masticatory behaviors are associated with MetS and MetS components.

    Hypertension is related to impaired mastication that causes malnutrition, declining the general health of older adults. This study assessed the role of dietary intake in the relationship between oral health and blood pressure. Eight hundred ninety-four adults aged ≥65 years who independently lived in rural regions of Japan participated in this study. Hypertension was classified according to the guidelines of the Japanese Society of Hypertension. The oral condition was evaluated by analyzing the remaining teeth, occlusal force, posterior occlusal support, masticatory performance, oral moisture, and oral bacterial level. Dietary intake was assessed using a brief self-administered dietary history questionnaire. Mann-Whitney U, chi-square, Kruskal-Wallis tests, and logistic regression analyses were used to elucidate the factors related to hypertension. Normotensive, hypertensive, and history of hypertension were observed in 30.9%, 23.8%, and 45.3% of the participants, respectively. The factors significantly associated with the hypertension were age, body mass index, posterior occlusal support condition, and sodium-to-potassium ratio related to salt intake and/or vegetable intake. Participants without posterior occlusion significantly had higher risk of hypertension (odds ratio = 1.72). This study suggested that there was an association between oral health and hypertension, while the loss of occlusal support may influence nutritional intake conditions.

    Numerous studies have evaluated the relationship between eating behavior and obesity, however few studies have objectively assessed eating behavior. Additionally, the association of masticatory behaviors with masticatory performance remains unclear. This study aimed to verify the relationship between masticatory performance and behavior measured by a wearable masticatory counter, and BMI. 365 healthy adults participated. Mastication behaviors, i.e. number of chews and bites, chewing rate, and chewing time, were measured using wearable masticatory counter while consuming one rice ball (100 g). Masticatory performance was evaluated using testing gummy jelly. Lifestyle habits including exercise, walking, and breakfast, were surveyed by questionnaire. The correlation coefficients between masticatory behaviors and performance and BMI were analyzed. Furthermore, multiple regression analysis was performed. The number of chews showed positive correlation with chewing rate, number of bites and chewing time, but no correlation with masticatory performance. BMI had weak but significant negative correlation with number of chews, bites, chewing time, and masticatory performance, but had no correlation with chewing rate. Multiple regression analysis revealed that BMI was associated with sex, age, number of chews, bites, masticatory performance, and walking speed. In conclusion, masticatory behavior and performance were not interrelated, but both were independently associated with BMI weakly.

    BACKGROUND: The tongue functions by modulating according to bolus volume when swallowing; however, associated tongue dynamics are unclear. OBJECTIVE: We aimed to clarify how tongue motion and tongue pressure change with bolus volume during swallowing. METHODS: Sixteen healthy volunteers (age 29.5 ± 3.8 years; 12 males, 4 females) were recruited. Two electromagnetic articulography markers were attached, one each on the anterior and posterior parts of the tongue, to measure motion. A sensor sheet, with five pressure-sensitive points, was attached to the hard palate to measure tongue pressure. Participants were asked to swallow 3 ml and 10 ml of water. Motion trajectory, maximum velocity, vertical displacement just before contact with the hard palate, and maximum magnitude and duration of tongue pressure were analysed. RESULTS: Tongue rotation was observed in the sagittal plane; its rate of appearance was significantly higher when swallowing 3 ml of water than when swallowing 10 ml, and the rate of rotation at posterior part was significantly higher than at the anterior part. The maximum velocity and vertical displacement were significantly greater when swallowing 10 ml of water than those when swallowing 3 ml of water. There was no significant difference in either the maximum magnitude of tongue pressure or maximum duration of tongue pressure between 3 ml and 10 ml. CONCLUSION: Bolus volume influenced the pattern of tongue motion; however, there was no difference in tongue pressure.

    咀嚼行動改善に対する啓発活動は多々行われているが、具体的な数値をもって咀嚼行動の改善を図る試みはほとんど行われていない。そこで、咀嚼回数計を使って自身の咀嚼行動を認識し、その問題点や改善点を考え、自発的な咀嚼習慣の行動変容を目指す「かむを測り、気づき、変えるための食育プロジェクト」を考案した。本研究の目的は、給食を用いて本プロジェクトを行い、発育期の児童に与える咀嚼行動変容効果を検討することである。対象は、新潟県内の1ヶ所の小学校5年生19名(男子7名、女子12名)とした。まず咀嚼回数計(シャープ社製bite-scan)を使用して3日間の給食時の咀嚼行動(咀嚼回数、一口あたりの咀嚼回数、食事時間、咀嚼テンポ、姿勢、動作の大きさ)を計測した。その後、咀嚼に関する授業を行うとともに最初の3日間の結果を配布して児童に自分の咀嚼行動の特徴について検討させた。さらに、各自が改善したい目標を掲げ次の5日間において咀嚼回数計を用いた介入を行った。最後に、3日間の給食を用いて再評価を行った。その結果、多くの児童たちは自身の咀嚼行動の長所と短所の両方に気づくことができた。また、介入後には咀嚼回数、食事時間、一口あたりの咀嚼回数、および咀嚼テンポは有意に増加し、姿勢、動作の大きさは有意に改善した。以上より、児童自身で立案した目標に向かって咀嚼行動変容を促した結果、効果的な行動変容を得ることができた。(著者抄録)

    BACKGROUND: Falls among older adults with a low bone density can lead to a bedridden state. Declining bone density increases the risk of falls resulting fractures in older adults. A person's physical performance is known to be closely related to bone density, and a relationship between the physical performance and the oral function is also known to exist. However, there currently is a lack of evidence regarding the relationship between bone density and the oral function. We assessed the relationship between the bone density and the both the oral function and physical performance among older adults. PATIENTS AND METHODS: 754 older adults aged 65 years or older who independently lived in rural regions and who were not taking any medications for osteoporosis participated. We checked all participants for osteoporosis using an ultrasonic bone density measuring device. Regarding the oral function, we evaluated the following factors: remaining teeth, occlusal support, masticatory performance, occlusal force, and tongue pressure. We also evaluated body mass index (BMI) and skeletal muscle mass Index as clinical characteristics. The normal walking speed, knee extension force and one-leg standing test were evaluated as physical performance. For the statistical analyses, we used the Mann-Whitney U test, chi-square test, the Kruskal-Wallis, and a multiple regression analysis. RESULTS: Eighty-one percent of the females and 58% of the males had osteoporosis or a decreased bone mass. The occlusal force, masticatory performance and the tongue pressure showed significant association with the bone density. The participants physical performance showed a significant association with their bone states except for walking speed. According to a multiple regression analysis, clinical characteristics (sex, age, BMI), one-leg standing and occlusal force showed independent associations with the bone density. It was suggested that the bone density tends to increase if the occlusal force is high and/or the one-leg standing test results are good. CONCLUSIONS: The bone density in the older adults showed a significant relationship not only with clinical characteristics or physical performance, but also with occlusal force. It may also be effective to confirm a good oral function in order to maintain healthy living for older adults.

    背景:最大舌圧と栄養状態との関係はまだ十分明らかにされていない。そこで,本研究では総合病院入院中の高齢患者の舌圧と栄養状態ならびに食形態との関連性について検討した。

    方法:2015年4月から2020年10月までに,総合病院歯科口腔外科に院内紹介された65歳以上の患者165名(男性96名,女性69名,平均年齢83.5±8.2歳)を対象とした。栄養リスク状態についてはGeriatric Nutritional Risk Indexを用いて中等度・高度群となし・軽度群の2群に分類し,食形態は常食・刻み食群とソフト食・ペースト食群の2群に分けて,それぞれ2群間で最大舌圧の差を検討した。

    結果:栄養リスク中等度・高度群(148名)の最大舌圧(14.1±9.6 kPa)は,栄養リスクなし・軽度群(19.8±10.8 kPa)と比べて有意に低かった(p=0.043)。一方,ソフト食・ペースト食群(88名)の最大舌圧(12.4±9.6 kPa)は,常食・刻み食群(16.9±9.6 kPa)と比べて有意に低かった(p=0.001)。また,ROC曲線により得られた栄養リスク中等度・高度ならびにソフト食・ペースト食を予測するカットオフ値は,それぞれ18.6 kPaと16.5 kPaであった。

    結論:総合病院入院高齢患者における最大舌圧の低下は,低栄養や食形態レベルの低下と関係していた。

    AIM: We aimed to clarify the association between deterioration of periodontal status and masticatory performance in a longitudinal follow-up study of a general urban population. MATERIALS AND METHODS: This study investigated 663 participants in the Suita study with no changes in the number of functional teeth or occlusal support areas during a 5-year follow-up period. Participants were classified into three groups according to changes in periodontal status during the survey period: a recovered group; a stable group; and a deteriorated group. Rate of masticatory performance change was calculated by subtracting the value at baseline from the value at follow-up and dividing the resulting value by the baseline value. RESULTS: Median rates of masticatory performance change were -11.7% in the recovered group, -19.2% in the stable group, and -30.8% in the deteriorated group, and these values were significantly different (p < .001). Multiple regression analysis revealed periodontal status group (recovered group: reference; stable group: p = .029; deteriorated group: p = .006) as an independent variable was significantly associated with the rate of masticatory performance change. CONCLUSION: The present results suggest that deterioration of periodontal status increases the risk of age-related declines in masticatory performance.

    Purpose This study investigated the impact of the renewal of a removable prosthesis on the masticatory function by subjective and objective measures and its variation among the types of occlusal support.Methods Seventy-eight patients who received newly fabricated removable denture patients participated in this study. For the objective assessment, masticatory performance was measured using test gummy jelly. For the subjective assessment, standardized questionnaires about food acceptability and the oral health-related quality of life (OHRQoL) were used. Pre- and post-insertion assessments were performed for each subject. Subjects were divided into three groups according to their posterior occlusion: with posterior occlusion (w/PO), without posterior occlusion (w/o PO) and edentulous. Wilcoxon's signed rank test was used to compare the pre- and post-treatment measurements of each assessment. The analysis of covariance and a multiple comparison were used to assess the effect of new dentures and differences due to occlusal support.Results The masticatory performance, OHRQoL and food acceptability following prosthodontic treatment were significantly improved by new denture insertion. The masticatory performance among groups varied to a relative degree. The rate of masticatory performance improvement for edentulous subjects was twice that in w/PO subjects. The OHRQoL was significantly lower in the w/o PO and edentulous groups with old denture than patients w/PO. The food acceptability improved most markedly in the edentulous group.Conclusions The improvement in the masticatory performance by new denture insertion varied among types of occlusal support. Re-establishing the occlusal support of edentulous patients may help restore their OHRQoL and improve food acceptability.

    (1) Background: The degree of satisfaction with dental treatment varies among patients, and the discrepancy may exist between the patient’s subjective evaluation and the objective assessment. Further, the optimal methods for increasing patient satisfaction with mastication remain unclear. This study aimed to identify factors affecting masticatory satisfaction in patients with removable partial dentures. (2) Methods: A total of 132 participants (71.0 ± 9.0 years) were included. Masticatory satisfaction was assessed on a visual analog scale. An oral health survey was conducted to assess the number of functional teeth, missing tooth classification: Kennedy classification, occlusal support: Eichner classification, and removable partial dentures wearing jaw. Objective masticatory performance was assessed using gummy jelly, while subjective masticatory ability was assessed using food acceptance status and oral health-related quality of life. The associations of these factors with masticatory satisfaction were assessed. (3) Results: Masticatory satisfaction among removable partial denture wearers was not significantly associated with gender, age, denture wearing jaw, Kennedy classification, and occlusal support. The degree of masticatory satisfaction was significantly greater with higher levels of masticatory function: masticatory performance, food acceptance score, and OHIP-14 score. The OHIP-14 score was the only significant explanatory variable for masticatory satisfaction in the multiple regression analysis; the strongest associations were with the “psychological discomfort” and “physical disability” subscales (p = 0.02 and p = 0.005, respectively). (4) Conclusions: Masticatory satisfaction among removable partial denture wearers was strongly associated with oral health-related quality of life, in which the ability to eat meals comfortably with removable partial dentures is the most important determinant of masticatory satisfaction.

    BACKGROUND: Although a food acceptance questionnaire is useful for subjective masticatory function assessments, its characteristics and limitations when applied to patients with removable dentures have been unclear. We therefore assessed the relationship between the subjective and objective masticatory function and explored whether or not a decreased masticatory function could be evaluated by food acceptance questionnaire. METHODS: One hundred and nineteen patients >60 years old with removable partial and/or complete dentures participated. Food acceptance score (FAS) was calculated by using Sato's questionnaire with 20 food items. Masticatory performance (MP) was assessed by a visual scoring method using a test gummy jelly (UHA Mikakuto). Simple/multiple regression analyses were performed to explain the objective masticatory function. The cut-off value of FAS was determined to predict a decreased masticatory function by sensitivity, specificity and receiver operating characteristics curve. RESULTS: No significant gender differences in MP or FAS were noted. Although both MP and FAS increased with the number of functional teeth, FAS was not significantly affected by age. The number of functional teeth, FAS and age had significant correlations with MP, with the number of functional teeth showing the strongest correlation. Multiple linear regression analyses identified the FAS as a significant explanatory variable for MP, and 70 was the optimal cut-off value for detecting a decreased masticatory function (MP score ≤ 2) in the diagnosis of 'oral hypofunction'. CONCLUSIONS: Using FAS to assess the MP was deemed appropriate, and a score of 70 was the optimal cut-off value for detecting a decreased masticatory function.

    Dentists often encounter patients suffering from psychological and social stress due to declines in masticatory performance, making this a critical issue to manage. We aimed to clarify the relationships between salivary stress markers as objective indices of chronic stress and objective masticatory performance in a general urban Japanese population. Data from 880 participants (mean age, 65.8 years) in the Suita study were used. Salivary interleukin (IL)-6 and cortisol concentrations were measured by enzyme-linked immunosorbent assay. Objective masticatory performance was determined by measuring the increase in surface area test gummy jelly after 30 times chewing. Participants were divided into two groups based on masticatory performance: a decreased group (lowest quartile) and a non-decreased group (second to fourth quartiles). Odds ratios (ORs) of higher salivary levels of stress markers (highest quartile) according to masticatory performance were estimated using logistic regression analysis adjusting for age, sex, periodontal status, salivary flow rate and smoking habit. Salivary IL-6 level was significantly higher in the decreased group than in the non-decreased group. Logistic regression analysis showed the adjusted OR for higher salivary IL-6 was significantly higher in the decreased group than in the non-decreased group (OR = 1.92; 95% confidence interval = 1.33-2.76; P < .001). No significant associations were found between salivary cortisol and decreased masticatory performance in any analyses. Declines in objective masticatory performance may correlate with higher salivary IL-6 level as an objective index of chronic stress.

    Decreases in masticatory function are believed to be related to the development of cardiovascular disease (CVD) through inappropriate nutritional intake. This study focused on maximum bite force (MBF), which is an objective, quantitative index of masticatory function, and its association with the development of CVD (stroke and coronary heart disease) was investigated. The subjects were 1547 participants of the Suita study with no history of CVD who underwent medical and dental health examinations between June 2008 and June 2013. In addition to undergoing a basic physical examination at baseline, their MBF was measured. They subsequently underwent follow-up surveys for the development of CVD (mean follow-up, 3.5 years). The association between baseline MBF and the development of CVD was investigated by multivariate adjustment using a Cox proportional hazards model. CVD developed in 32 subjects during follow-up. The trend test showed a significant association between baseline MBF and CVD in a model that combined men and women. When analysed by sex, the trend test found a significant association between baseline MBF and CVD in women. Low MBF, which is an objective and quantitative index of masticatory function, may be a risk factor for the development of CVD.

    To provide appropriate foods for elderly people with eating difficulties, it is necessary to take account of the ability of compensatory mastication such as tongue squeezing. However, the biomechanics of tongue squeezing is still unclear. The aim of present study is to investigate the effect of the initial mechanical properties of gels on the change in tongue pressure production during squeezing and swallowing. As test sample, nine kinds of gels with three fracture force and three fracture strain were prepared. Tongue pressure during squeezing and swallowing gels was measured by using an ultra-thin tongue pressure sensor with five measuring points attached on the hard palate in seven healthy participants, and analyzed at four phases; Initial squeeze, Middle squeeze, Last squeeze, and Swallowing. The maximal magnitude of tongue pressure was increased for gels with higher fracture force at most measuring points and was decreased for gels with higher fracture strain at some measuring points on the median line during Initial and Middle squeezing. However, no influence by fracture force and strain was found in magnitude during Last squeezing and Swallowing. The duration of tongue pressure increased for gels with higher force at most measuring points during Middle squeezing, although no influence by strain was found during each phase. The results clearly show how the initial fracture properties of gels influence on tongue pressure production during each phase of food oral processing, which clarified one aspect of squeezing with tongue, as the compensatory mastication.

    To extract the variables which can well explain human textural perceptions during swallowing, the laryngeal movement was investigated dynamically and synchronously with the activities of the suprahyoid musculature and the tongue using gel-type foods. Nine gel samples were prepared by changing fracture force at constant fracture strain or by changing fracture strain at constant fracture force based on the uniaxial compression test. These gels were cut into 3 mm cubes for mimicking food bolus and then subjected to Texture Profile Analysis, sensory test, and in vivo physiological measurements. Sensory test and in vivo measurements were performed on 8 healthy adult subjects (all male of ay. 30.0 +/- 6.9 yr). After placing 10 g of the model bolus in his mouth and holding them for 3 sec, each subject was asked to swallow the whole amount of them at one time without chewing. Sensory test targeted perceived hardness, bolus uniformity, and swallowing ease at the time of swallowing and evaluated them on Visual Analog Scale. Results indicated that perceived hardness highly correlated with the activity of the suprahyoid musculature from electromyography. Also, perceived bolus uniformity and swallowing ease highly correlated with the duration of swallowing from the laryngeal movement and the tongue activity from the tongue pressure measurement, respectively. In vivo measurements evaluated swallowing-related textural perceptions better than the conventional mechanical measurements, and their predictions were successful with high accuracy by the combination of these 3 in vivo measurement variables.

    BACKGROUND: The aim of this study was to evaluate the validity of a dysphagia screening test (DST) in patients who have undergone resection for head and neck cancer (HNC). In addition, we examined whether or not combined effects of DSTs improve the detection accuracy of penetration/aspiration. METHODS: Thirty-six HNC patients were participated. The DST consisted of the repetitive saliva swallowing test (RSST), the water swallowing test (WST), the modified water swallowing test (MWST), the food test (FT), and tongue pressure. A videofluoroscopic swallowing study was conducted, and the penetration-aspiration scale was used for scoring. For statistical analyses, we used the receiver operating characteristic (ROC) analysis. Furthermore, the accuracy of the determination of penetration/aspiration was evaluated by combining two or three DSTs. RESULTS: The penetration/aspiration could be predicted with moderate accuracy based on MWST and FT. The area under the ROC curve (AUC) values of the MWST and FT were 0.76 (p = 0.03) and 0.80 (p = 0.050), and the sensitivity/specificity was 0.9/0.61 (MWST) and 0.8/0.8 (FT), respectively. As a result of combining 2 or 3 DSTs, the combination of "MWST and FT" was the most accurate, with an AUC of 0.87 (p = 0.02). The combination of three tests had lower accuracy than the combination of two tests. CONCLUSION: Based on our results, it is recommended that MWST or FT be used when only one type of DST is performed. In addition, the combination of two DSTs may detect aspiration patients more accurately than one alone.

    OBJECTIVES: Declines in masticatory performance might be a risk factor for worsening nutritional intake and result in general frailty. The present study constructed and investigated a method to predict the extent to which objective masticatory performance declines with age in cases with poor oral health status. METHODS: Participants comprised 1201 participants in the Suita study with dental checkup at both baseline and follow-up (500 men and 701 women; age at baseline, 65.6 ± 7.8 years; mean follow-up, 5.1 ± 1.1 years). First, multiple linear regression analysis was performed with masticatory performance at follow-up as the dependent variable and sex as well as baseline age, number of functional teeth, maximum bite force, occlusal support, periodontal status, salivary flow rate, and masticatory performance as independent variables. Scores were assigned to each factor based on the standardized partial regression coefficient obtained from multiple linear regression analysis. Participants were divided into quintile groups (Q1-Q5) based on total scores for factors, and rates of masticatory performance change for each group were calculated and compared. RESULTS: Mean rates of masticatory performance change in groups Q1-Q5 from the model to predict declining masticatory performance were: Q1, -9.7%; Q2, -12.7%; Q3, -18.0%; Q4, -19.9%; and Q5, -29.8%.Thus there was a trend for masticatory performance to decrease with decreasing score. CONCLUSIONS: The model developed in this study quantitatively predicted declines in masticatory performance after approximately 5 years. CLINICAL SIGNIFICANCE: We developed a model for predicting the extent to which masticatory performance will change over the next 5 years. This model may offer a useful tool when taking measures to prevent declines in masticatory performance with aging.

    Mastication is a physiological process whereby food is comminuted and mixed with saliva to form a swallowable bolus; it is also the initial process for retronasal aroma that is released from foods to receptors in the nose. However, the influence of mastication state on retronasal aroma is poorly understood. The purpose of this study was to investigate the relationship between aroma concentration and factors related to mastication state. The study design was an analytical observational study. Twelve male volunteers (age, 26.5 ± 2.7 years) were recruited and divided into five and seven participants in the low and high masticatory performance groups, respectively. The stimulated salivary flow rate was measured while participants chewed paraffin wax. First, an odor sensor was placed in the nostril, and the aroma concentration was measured over time as participants chewed an orange-flavored gummy jelly standardized for masticatory performance assessment until swallowing; chewing strokes were counted to determine swallowing thresholds. Next, participants were instructed to chew the gummy jelly for a certain number of strokes (i.e., 50 or 100% of swallowing thresholds, as well as 30 strokes) and expectorate the jelly without swallowing. The surface area of comminuted jelly at 30 chewing strokes was defined as masticatory performance. Maximum and slope of aroma concentration, surface area, number of chewing strokes, and stimulated salivary flow rate were compared between low and high masticatory performance groups. Statistical significance was set at α = 0.05. At 30 chewing strokes, the maximum aroma concentration and the slope were significantly greater in the high masticatory performance group than in the low masticatory performance group. There was a positive correlation between the maximum aroma concentration and the number of chewing strokes with aroma release in both groups. No significant correlation was found between the maximum aroma concentration and the stimulated salivary flow rate. However, multiple regression analysis (with aroma concentration as a dependent variable) showed that the increase in surface area, the number of chewing strokes, and the stimulated salivary flow rate were significant explanatory variables. The results suggested that retronasal aroma was influenced by mastication state and salivary flow rate during chewing.

    Objectives: Declined masticatory function has recently been receiving attention as a risk factor for poor general health. The present longitudinal analysis was conducted to clarify the relationship between decreased masticatory performance and the development of the metabolic syndrome (MetS) in a general urban cohort in Japan. Methods: We surveyed 599 participants (254 men, 345 women; mean age at baseline, 65.8 ± 7.8 years) who underwent physical health checkups in the Suita study. We evaluated masticatory performance at baseline using test gummy jelly and divided participants into two groups: a "Lower group," comprising participants in the lower 25% of the masticatory performance at baseline; and a "Normal group," comprising all others. We estimated hazard ratios (HRs) for the Lower group by using Cox proportional hazard regression analysis to develop the MetS and the components of the MetS at follow-up, adjusting for age, smoking status, and periodontal status. Results: On Cox proportional hazard regression analysis, the multivariable adjusted hazard ratio for the development of the MetS in the Lower group was 2.24 (95% confidence interval, 1.12-4.50) in men. The multivariable adjusted hazard ratio for the development of high blood pressure was 3.12 (1.42-6.87), for high triglycerides was 2.82 (1.18-6.76), and for high fasting plasma glucose was 2.65 (1.00-7.00) in men. Conclusions: Lower masticatory performance suggested to be a risk factor for the development of the MetS as well as MetS components such as high blood pressure, high triglycerides, and high fasting plasma glucose in Japanese men.

    © 2020 by the authors. Licensee MDPI, Basel, Switzerland. It is often assumed that oral hypofunction is associated with social withdrawal in older adults because decreased motor function is related to decreased oral function. However, few studies have examined the relationship between social withdrawal in older adults and oral function. This longitudinal study aimed to clarify the relationship between changes in the level of social withdrawal and oral function in independent older adults. Participants were 427 older adults aged 65 years or older who took part in a self-administered questionnaire from 2016 to 2017 (baseline), and again two years later (follow-up). At baseline, 17 items related to oral function and confounding factors related to withdrawal, physical condition, physical function, and cognitive function were evaluated. A Cox proportional hazard model was used to examine the oral functions that negatively impact social withdrawal. The following factors were significantly associated with the worsening of social withdrawal: the number of remaining teeth, gingival condition, occlusal force, masticatory efficiency, and items related to swallowing and dry mouth. Older adults with cognitive issues who walk slowly and have a weak knee extension muscle were also significantly more likely to have oral frailty. Those who were found to have oral frailty at baseline were 1.8 times more likely to develop withdrawal compared to those with robust oral function. The results indicated that the worsening of withdrawal was associated with oral hypofunction at baseline. Since oral hypofunction was associated with the worsening of social withdrawal in older adults, it is important to maintain older adults’ oral function.

    BACKGROUND: Tongue motor biomechanics during swallowing was not fully elucidated due to the technical difficulty. OBJECTIVE: To evaluate the relationship between tongue motion and tongue pressure production by simultaneously measuring tongue motion and tongue pressure during water swallowing. METHODS: In 12 healthy male participants (mean age, 30.8 ± 4.2 years), tongue pressure and tongue motion trajectory during dipper- and tipper-type swallows of 3 mL of water were measured using a sensor sheet system equipped with five sensing points and an electromagnetic articulography, respectively. The temporal correlation between motion of anterior/posterior tongue and tongue pressure production during swallowing was evaluated on the synchronised waveforms. RESULTS: In the dipper-type swallow, a similar up-and-down motion pattern in vertical direction was observed among all participants before tongue pressure production. Those motion patterns were common at the anterior and posterior tongue locations with a temporal difference in some segment of tongue motion. On the other hand, tongue directly attached to hard palate with temporal synchronicity between the anterior and posterior parts. In both types of swallow, a strong temporal correlation was found between the timing of tongue-palate contact and the Onset of tongue pressure by intra-class correlation coefficients. CONCLUSION: From the simultaneous measurement of tongue motion and tongue pressure production, the tongue motion pattern during water swallowing and the temporal correlation between tongue motion and tongue pressure production were elucidated.

    PURPOSE: A decrease in posterior occlusal support is considered to increase the load on remaining teeth and thus accelerate tooth loss. Therefore, a follow-up study was carried out to perform a longitudinal analysis of the association between the posterior occlusal support region and tooth loss. METHODS: The participants of the study were 806 Suita Study participants who underwent physical health checkups both at baseline and at follow-up. The participants were classified into three groups by posterior occlusal support area (POSA) using the Eichner Index at baseline: Perfect POSA group, Eichner A; Decreased POSA group, Eichner B1-3; and Lost POSA group, Eichner B4 and Eichner C1-2. Participants were also classified into two groups according to whether they had tooth loss during the follow-up period. Tooth loss risk factors were investigated through the construction of logistic regression models with tooth loss as the dependent variable and posterior occlusal support, sex, age, periodontal disease, stimulated salivary flow rate, smoking habit, drinking habit, denture wearing, utilization of dental services, brushing habits, diabetes mellitus, osteoporosis and number of years of follow-up as independent variables. RESULTS: In the results of the logistic regression model, the adjusted odds ratio (95%CI) for tooth loss with the Perfect POSA group as the reference was 3.19 (1.98-5.14) for the Decreased POSA group and 4.57 (1.97-10.62) for the Lost POSA group. CONCLUSIONS: This study showed that decreased POSA accelerated tooth loss in the general urban population.

    学童期の歯列交換期は、成人の咀嚼機能へと発達する重要な時期となっている。また、咀嚼機能は歯の発育段階(歯齢)や体格・身体機能に影響されるといわれている。しかしながら、客観的な検討はまだほとんど行われていない。そこで咀嚼能力測定用グミゼリー(咬断能力)および色変わりガム(混合能力)を用いて、歯列交換期の学童における咀嚼能力を2つの異なる観点から客観的に評価し、さらに体格・身体機能の関連について検討することとした。対象者は、2015年11月から2017年12月の間に兵庫県の某小学校において学校健診を受けた4〜6年生のべ630名(男児319名、女児311名)を対象とした。歯科健診の結果からHellmanの咬合発育段階に準じて、IIIA群、IIIB群、IIIC群、IVA群に分類した。咬断能力と混合能力はそれぞれスコア法により評価した。また、身長、体重、握力、最大歩行速度を測定し、各歯齢における咀嚼能率スコアと体格・身体能力との関連について、Spearmanの順位相関係数、Mann-Whitney U test、線形混合モデルおよびpost-hoc testを用いて統計学的検討を行った。その結果、咬断能力は側方歯群交換期(IIIB)でいったん有意に低下した後、交換期終了後は交換期以前に比べて有意に増加したが、混合能力は低下することなく、歯齢とともに増加する傾向を示した。また、咀嚼能力と体格・身体機能の間には、歯齢によって弱い相関を認めた。これらの結果から、側方歯群交換期における客観的な咀嚼能力の推移は、咬断能力と混合能力との間で異なることが明らかとなり、食事指導において考慮すべきであることが示唆された。(著者抄録)

    Masticatory performance of subjects from a general urban population was examined by measurement at baseline and again at follow-up, to clarify whether periodical utilization of dental services (PUDS) is effective in maintaining masticatory performance. Subjects comprised 1010 people (414 males, 596 females; mean age at baseline, 65.7 ± 7.8 years) who participated in the Suita study with dental checkups at both baseline and follow-up (mean follow-up, 5.2 ± 1.5 years). Number of functional teeth, occlusal support, periodontal status, masticatory performance, maximum bite force, and salivary flow rate were surveyed. Subjects were divided into a with-PUDS group (n = 430), who responded at both baseline and follow-up that they regularly utilized dental services, and a without-PUDS group (n = 580), who responded otherwise. To evaluate longitudinal changes in masticatory performance over the study period, the rate of masticatory performance change was calculated by dividing the difference in masticatory performance between follow-up and baseline by the masticatory performance at baseline. The relationship between the presence of PUDS and the rate of masticatory performance change was investigated by multiple linear regression analysis. Analysis was performed using a model with number of functional teeth as an independent variable (number of functional teeth model), and a model with occlusal support as an independent variable (occlusal support model). Multiple linear regression analysis identified PUDS as significantly associated with the rate of masticatory performance change in both the number of functional teeth model and the occlusal support model. PUDS is likely to prove effective in ameliorating reductions in masticatory performance over time.

    BACKGROUND: Pharyngeal residue can trigger aspiration and choking after swallowing. Various studies to assess the amount of pharyngeal residue have been conducted; however, an easy and quantitative method is yet to be established. The aroma released from the pharyngeal residue is thought to be delivered from the pharynx to the nasal cavity via velopharynx by expiration, that is, retronasal pathway. OBJECTIVE: This study verified that the amount of pharyngeal residue could be estimated by aroma intensity. METHODS: Ten healthy adult subjects had tubes in from the oral cavity to the pharynx. Varying amounts of essence were dispensed into the pharynx through the tube either at rest or after swallowing the essence. Pharyngeal residue was simulated by retention essence in the pharynx without swallowing. An odour sensor was placed in the nostril, and the aroma intensity of the retained essence was measured over time. RESULTS: The aroma intensity level flattened after a certain period of time had elapsed, and a significant correlation was found between the amount of essence dispensed and the flattened aroma intensity, both at rest and after swallowing. Furthermore, to estimate in a short period of time, changes in aroma intensity over time were estimated by fitting to a decay curve. The estimated intensity at convergence, calculated from the fitted curve from 80 to 120 seconds after swallowing, was significantly correlated to the measured intensity. CONCLUSION: The amount of pharyngeal residue can be estimated in a short period of time by measuring the aroma intensity.

    PURPOSE: The association between periodontal disease and carotid atherosclerosis has been widely discussed, but to our knowledge, no population-based studies have been conducted on the association between masticatory ability and carotid atherosclerosis. We aimed to clarify the hypothesis that objectively accessed masticatory performance is related to increased intima-media thickness (IMT) in a general urban population. METHODS: We studied 1,484 Japanese (mean age: 66.9 y) from the Suita study. Masticatory performance was measured using test gummy jelly, and periodontal status was evaluated using the Community Periodontal Index (CPI). Carotid ultrasonography was performed to measure maximum IMT (max-IMT) in the entire area of the carotid arteries. Analysis of covariance was used to compare max-IMT according to quartiles of masticatory performance adjusted by cardiovascular risk factors and periodontal status. RESULTS: Multivariable-adjusted max-IMT (standard error) was significantly higher in the lowest masticatory performance quartile group (decreased group) (1.58 ± 0.03 and 1.44 ± 0.03 mm) than in the 2nd to 4th quartiles combined (non-decreased groups) in both sexes (1.48 ± 0.02 mm, trend P = 0.038) and in women (1.34 ± 0.02 mm, trend P = 0.013), respectively. In participants without cardiovascular risk factors (n = 250), multivariable-adjusted max-IMT was significantly higher in the decreased (1.54 ± 0.06, 2.08 ± 0.22, and 1.42 ± 0.06 mm) than in the non-decreased groups in both sexes (1.31 ± 0.04 mm, trend P = 0.006), in men (1.41 ± 0.12 mm, trend P = 0.028), and in women (1.28 ± 0.04 mm, trend P = 0.073). CONCLUSIONS: These findings suggest that decreased masticatory performance may be related to carotid IMT progression in the general urban Japanese population.

    外科的切除を受けた患者の咀嚼機能障害と発音機能障害に対する下顎顎義歯の有効性について検討した。日本医学図書館協会に系統的な文献検索を依頼するとともに、顎顔面補綴診療ガイドライン2009年版を参考に適宜文献を追加した。検索期間は1996年1月〜2018年12月とし、複数のKW検索を行った。その結果、PubMed合計304論文、医中誌Web合計312論文の総計616論文が検索され、そのうち選択基準を満たす16編(症例103例)を今回の対象論文とした。対象論文に含まれる症例は、多種多様な下顎顎欠損形態を有していた。下顎骨再建が確認できたのは44例、非再建は55例であった。顎義歯装着後に下顎顎骨の再建・非再建に関わらず下顎運動の円滑な運動路、タッピング時の咬頭嵌合位への収束、咀嚼時の筋活動リズムの安定性向上が得られたため咀嚼運動が改善され、咀嚼効率の向上、摂取可能食品の増加、咀嚼から嚥下までの時間短縮による咀嚼機能の向上・回復の確認が報告されていた。基本的に患側での咀嚼機能回復度は低いと認識する必要があり、下顎顎義歯の装着は一般的に機能回復の即効性が低いものの、装着後経時的に下顎運動が安定し、咀嚼運動リズムが整うことによって咀嚼機能が回復されると考えられた。発音機能については、下顎顎義歯装着患者に下顎の患側偏位を抑制し下顎運動を誘導するパラタルランプを応用した症例の場合、発音時の下顎位が安定することで発音明瞭度が向上し、患者の満足が得られたとの報告があった。また、顎義歯を装着することで人工歯や義歯床による欠損組織の形態が回復し、審美的回復に患者の満足度を得たと考えられた。

    OBJECTIVE: The aim of this study was to evaluate tongue movement and its biomechanical effects during squeezing, one of the oral strategies for processing soft foods, by tongue pressure sensors, videofluorography, and surface electromyography. DESIGN: Fifteen healthy men (mean age, 31.0 ± 4.1 years) without dysphagia were recruited. A 0.1-mm-thick pressure sensor sheet with five measuring points, videofluorography, and surface electromyography were used for synchronous measurements of tongue pressure, hyoid movement, and suprahyoid muscles activity, respectively, while squeezing 5 mL of gels. Amplitude, duration, area, and their sequential order during initial squeezing were analyzed. Differences in hyoid position at the onset, peak, and offset of hyoid movement were also analyzed. RESULTS: At the beginning of initial squeezing, tongue pressure at the middle area of the hard palate, hyoid movement, and suprahyoid muscle activity appeared simultaneously, followed by tongue pressure at the anterior area and then at the posterior area. When the hyoid was in an elevated position, the amplitude of suprahyoid muscle activity and tongue pressure peaked. At the end of initial squeezing, the hyoid position at the offset of hyoid excursion was superior to that at the onset. All evaluation items of tongue pressure, hyoid movement, and suprahyoid muscle activity were modulated according to the texture of gels. CONCLUSIONS: During initial squeezing, tongue pressure, hyoid movement, and suprahyoid muscle activity were coordinated while being modulated by the food texture. At the end of initial squeezing, the hyoid was maintained in an elevated position, which might be beneficial for subsequent squeezing.

    PURPOSE: Masticatory performance can be measured through elution of glucose or beta-carotene from comminuted gummy jelly. However, these methods require special devices. Additionally, occasional/unintentional swallowing or inadequate collection of comminuted particles of gummy jelly in the oral cavity may cause measurement errors. Therefore, we devised a new photographic method to estimate the increase in surface area and weight of comminuted gummy jelly. This study aimed to verify the accuracy of this method. METHODS: Initially, fifty images depicting the comminuted pieces in a special box were prepared. Then, the increase in surface area was measured using a fully-automated method, and the weight was measured. The size and angle of each image were adjusted based on markers located at the four corners of the box. From these photographic images, the area, perimeter, color average, color deviation, side area, and amount of surface roughness for each particle was calculated, and multiple regression analysis was performed to estimate the surface area and weight. The relationship between the estimated values and the values measured with the fully-automated device and by weight were analyzed. RESULTS: The intra-class correlation coefficient between the estimated value and the value from the fully-automated method was r = 0.956. This high correlation was also obtained under different photographic conditions. Furthermore, for determining whether 80% or less gummy jelly was collected, the sensitivity was 100% and the specificity was 91%. CONCLUSIONS: The newly developed photographic method is valuable because it is accessible and may assist in achieving reliable evaluation of masticatory performance.

    Older adults with disorders of mastication and swallowing are often fed soft foods such as jelly or puree. The texture of such semi-solid foods allows them to be squeezed between the tongue and palate rather than being chewed. However, it is difficult to visually identify such strategies for the oral processing of food. This study aimed to test the hypothesis that there is a difference in the sequential coordination between the masseter and supra-hyoid muscles, and to identify feeding behaviors such as chewing and squeezing using electromyography. Seventeen male subjects (mean age: 30.8 years) were recruited. Four kinds of gels were prepared (two kinds of fracture force and fracture strain) as test samples. Subjects were instructed to consume the gels in three ways: squeezing with the tongue, chewing with the teeth and eating freely until swallowing. The amount of squeezing/chewing and the consumption time was unlimited. The masseter and supra-hyoid muscle activity were recorded during the entire consumption time and videofluorography was simultaneously recorded during each ingestion. Lissajous figures were made from the electromyographic activity of the two groups of muscles during the first stroke, and a regression line was made to determine the gradient of each figure to compare squeezing and chewing using the Mann-Whitney U-test. The masseter and supra-hyoid muscles were active simultaneously during squeezing with the tongue. However, the masseter was active after the supra-hyoid during chewing. The gradient of the regression line from the Lissajous figures between the masseter and supra-hyoid muscle activity was positive during squeezing, but negative during chewing. Analysis of the ROC curve showed that the cutoff value of the gradient for differentiating feeding behaviors was 0.097, with a sensitivity of 95.3% and specificity of 98.4%. When we allocated 68 free intakes into squeezing and chewing according to this cutoff value, we could distinguish with good precision, and the accuracy, sensitivity, and specificity were 86.8, 91.1, and 66.7% respectively. These results suggest that certain aspects of muscle activity differed among oral processing methods. Lissajous analysis of muscle activity was useful for identifying ingestion behaviors.

    © 2020 by the American College of Prosthodontists Purpose: To measure masticatory performance (MP) in partially edentulous patients when wearing removable partial dentures (RPDs) versus when not wearing RPDs, and to identify factors that could enable clinical evaluations related to differences in MP. Materials and methods: This study consisted of 87 partially edentulous patients (57 females, 30 males; mean age, 69.41 ± 8.85 years) categorized as Eichner classification B who habitually wore RPDs. MP was evaluated while wearing versus while not wearing RPDs using test gummy jellies. The participants were categorized into four groups by the presence of occlusal contacts in one to three of the molar and premolar regions (occlusal support), or in the anterior region only, according to the Eichner index (B1-B4). The participants were also categorized according to the jaw on which the RPDs were worn and the Kennedy classification, and evaluated in regard to changes in MP resulting from wearing RPDs. Additionally, the rate of change in MP (MP-rv) was calculated for each participant using MP when not wearing RPDs as a reference, and factors affecting MP-rv were evaluated using single or multiple regression analysis and the Kruskal-Wallis test with multiple comparisons. Results: Significant increases in MP-rv were observed for all participants and for those with occlusal support in two (p = 0.006) and three regions (p = 0.019); however, no significant differences were observed when wearing and not wearing RPDs in participants with (p = 0.090) and those without occlusal support in one region (p = 0.474). With respect to the jaw on which the RPDs were worn, only maxillary or both maxillary/mandibular RPDs tended to have higher MP-rvs than did only mandibular jaws. The results of the multiple regression analysis showed that Kennedy Class I edentulous arches were a factor in increasing MP-rv (standard partial regression coefficient = 0.46, p < 0.05). Conclusion: According to the results of this study, among various factors on the degree of improvement in masticatory performance by wearing RPDs, bilateral missing posterior teeth might be a predictor for achieving clinical improvement.

    目的:舌接触補助床(PAP)装着前後の舌圧の変化を明らかにすること。方法:全国の17施設においてPAPによる治療を行った摂食嚥下障害患者を後方視的に調査した。PAP装着前後ならびに再評価時の3回最大舌圧が測定されていたのは51例であり、これらを口腔腫瘍などの器質的障害群23例と脳血管疾患などの機能的障害群28例に分類した。PAP装着前後ならびに再評価時の最大舌圧の比較、PAP装着直後の即時的舌圧変化量と再評価時までの長期的舌圧変化量の関係を検討した。また、29例で測定されていた嚥下時舌圧の装着前後の変化についても検討した。結果:器質的障害群の最大舌圧は、装着前9.6±8.8kPa、装着直後16.4±10.3kPa、再評価時20.7±11.2kPaと増加した(p<0.01)。また、即時的舌圧変化量と長期的舌圧変化量には強い正の相関を認めた(r=0.81、p<0.01)。機能的障害群の最大舌圧は、装着前12.1±7.0kPa、装着直後15.5±8.0kPa、再評価時18.7±7.7kPaと増加しており(p<0.01)、即時的舌圧変化量と長期的舌圧変化量には中等度の正の相関を認めた(r=0.51、p<0.01)。嚥下時舌圧もPAP装着前の3.0±3.5kPaから装着直後の11.8±9.2kPaに増加していた(p<0.01)。結論:最大舌圧は、PAP装着後に即時的および長期的に増加し、即時的効果が得られた者ほど長期的な効果も期待できる傾向を認めた。また、嚥下時舌圧もPAP装着により増加することが示された。(著者抄録)

    BACKGROUND: Several methods exist for objectively evaluating chewing efficiency by using gummy jelly. However, the validity of the subjective visual evaluation of chewing efficiency has not been assessed. OBJECTIVE: To verify with an epidemiological study, the validity of a visual scoring method using gummy jelly by testing the relationship between masticatory performance (MP) using a fully automatic measuring system and visual score (VS) using a visual scoring method. METHODS: Community-dwelling elderly individuals (n = 1234) ≥70 years old participated. One evaluator measured VS consecutively after participants chewed the gummy jelly (ie, actual-VS). The chewed jelly was photographed. Two evaluators used the photograph to measure the gummy jelly (ie, photo-VS). To test the validity of both methods, the correlation between actual-VS and MP and between photo-VS and MP were analysed. Inter-rater reliability between the evaluators of photo-VS was analysed. RESULTS: Significant correlations existed between actual-VS and MP and between photo-VS and MP (r = 0.86-0.87; P < 0.001). The intra-class correlation coefficient of the inter-rater reliability for photo-VS was very high (0.93; P < 0.001; 95% confidence interval: 0.877-0.953); however, the distribution of photo-VS deviated slightly from the actual-VS. A large coefficient of variation in the MP for low VSs suggested the influence of incomplete comminution, which was not reflected by the VS, and the accidental swallowing of small pieces during chewing. CONCLUSION: The VS deviated slightly from the MP calculated using a fully automated method; however, the VS can be utilised for epidemiological surveys with numerous participants.

    INTRODUCTION: Although previous studies have identified various factors related to masticatory performance, which factors affect longitudinal changes in masticatory performance have not been clarified. OBJECTIVES: We aimed to clarify factors involved in changes to masticatory performance and construct models from factors related to masticatory performance in a longitudinal study of a general urban population in Japan. METHODS: A total of 1,005 Japanese subjects (411 men, 594 women; mean age at baseline, 65.7 ± 7.7 years; mean follow-up period, 5.0 ± 0.9 years) were included in the Suita study. These subjects participated in dental checkups both at baseline (June 2008-December 2011) and at follow-up (June 2013-January 2017). The number of functional teeth and occlusal support areas was recorded and the latter assessed using the Eichner index. Subjects' periodontal status was evaluated based on the Community Periodontal Index. Masticatory performance was determined using test gummy jelly. Factors affecting masticatory performance at follow-up and the degree of their effect were investigated by multiple linear regression analysis. RESULTS: In multiple linear regression analysis with masticatory performance at follow-up as the dependent variable, baseline age, masticatory performance, number of functional teeth, and maximum bite force were significant independent variables. The results of multiple linear regression analyses by occlusal support at baseline identified only maximum bite force at baseline in subjects who were Eichner A and baseline age, masticatory performance, and number of functional teeth in subjects who were Eichner B as significant independent variables concerning masticatory performance at follow-up. CONCLUSION: Our study showed a relationship between longitudinal changes in masticatory performance and age, number of functional teeth, and maximum bite force and furthermore showed that the effects of these factors vary according to the residual number of occlusal support areas. KNOWLEDGE TRANSFER STATEMENT: Patients and clinicians should recognize the importance of objective and quantitative assessment for chewing efficiency and understand that various factors are related to longitudinal changes in masticatory performance. The results of this study can provide basic data for preventing or improving the decline in masticatory performance for elderly people with varying numbers of occlusal support areas.

    Our previous study regarding the tongue-hold swallow (THS) demonstrated that the tongue-to-palate contact during THS could be influenced by the maximum tongue protrusion length (MTPL) of individual subjects, resulting in two different patterns of pressure generation. The present study further analyzed the influence of MTPL on the tongue pressure production along with submental surface electromyography (sEMG) during THS, in order to establish an index to better control THS effects. Tongue pressure using a sensor sheet system and concurrent submental sEMG activities were measured during swallowing tasks in 18 healthy young adults. Task conditions comprised THS at two different degrees of tongue protrusion and dry swallow. Tongue pressures and sEMG activities were compared among three task conditions, and correlations of MTPL with tongue pressure were also investigated. Additionally, a ROC curve was used to find a cut-off value for MTPL to predict changes (increases and decreases) in tongue pressure during THS. The duration and the amount of submental muscle activity increased concurrently during THS. Two trends were shown on the change in tongue pressure at the posterior-circumferential part of the hard palate during THS compared to dry swallow; the maximal magnitude and the integrated value of tongue pressure increased in some subjects, while these values decreased in others. Thirty-two millimeters was found to be the cut-off value of MTPL, which distinguishes increase/decrease pattern of tongue pressure with sensitivities of 60.0-85.7%. The present finding suggests that more reliable THS effects should be attainable using MTPL to set the tongue-hold position.

    The physiological mechanisms underlying Stage II transport (STII), during which comminuted solid food is transported from the oral cavity into the meso-pharynx for aggregation into a pre-swallow bolus, have yet to be clarified. The purpose of the present study was to investigate relationships between tongue-palate contact during mastication and incidence of STII by synchronised analysis of tongue pressure production on a hard palate and video-endoscopic (VE) images during mastication. Tongue pressure at 5 measuring points with an ultra-thin sensor sheet attached to the hard palate and trans-nasal VE images while masticating corned beef was recorded for 12 healthy subjects. All recordings were divided into 2 groups: mastication with STII and without STII. Tongue pressure duration was longer at the anterior-median part in the group with STII than in the group without STII. Integrated values of tongue pressure were greater at the anterior-median parts and posterior circumferential part in the group with STII. Integrated values of tongue pressure per second were greater in late-stage mastication than in early-stage mastication in the group with STII. These results suggest that the tongue-palate contacting at the anterior-median and post-circumferential parts of the hard palate is related with the incidence of STII.

    The effects of bolus volume and flow time on the sequential coordination of tongue pressure (TP) and pharyngeal pressure (PP), which are important in the biomechanics of swallowing, are unclear. In this study, we measured TP and PP simultaneously in 10 healthy adults at multiple points during dry swallowing and the swallowing of 5 ml and 15 ml of liquids with different viscosities, and investigated changes in the timing of the onset, peak, and offset of these pressures. TP was measured using a sensor sheet system with five measuring points on the hard palate, and PP was measured using a manometry catheter with four measuring points. The order and correlations of sequential events, such as onset, peak, and offset times of pressure production, at each pressure measuring point were analyzed on the synchronized waveforms. We found that the differences between the TP and PP onset times decreased when the bolus volume was larger. The change in bolus volume had very little effect on peak time or offset time. The flow time of the bolus affected the appearance of onset and peak time for both TP and PP. A time difference between TP and PP emerged as the flow time increased, with TP starting to appear before PP. This may be the first detailed analysis of pressure-flow dynamics that treats the mouth and pharynx as a single functional unit. We believe that our analysis is an important step toward extending future research to include a wider range of age groups and dysphagia patients.

    The purpose of this study was to help provide data to help to implement effective rehabilitation following surgery for oral cancer by comparing tongue pressure production for water and thickened water from the anterior and posterior parts of the tongue during swallowing. Ten healthy volunteers (7 men, 3 women
    age 27.6 ± 1.5 years) participated in the experiments. Tongue pressure during 3 mL water and 3 mL thickened water at the anterior and posterior tongue during swallowing was measured using a sensor sheet system with five measuring points on the hard palate. The sequential order of the points, maximal magnitude and duration of tongue pressure at each point were compared based on water viscosity and tongue ingestion site. There was a common pattern in the sequential order of tongue pressure generation among the two swallowing conditions. The maximal magnitude of tongue pressure was significantly higher when swallowing thickened water than when swallowing water at all points except for the anterior-median and mid-median part. Moreover, the pressure at all sites during posterior ingestions was significantly lower than that during anterior ingestion. The present results provide mean values of tongue pressure during voluntarily triggered swallowing in anterior ingestion and posterior ingestion in young, healthy dentate individuals
    these values can be clinically referenced for tongue pressure measurement in the evaluation of patients with dysphagia. The use of reference values may help streamline the diagnosis, treatment and rehabilitation of dysphagia.

    This study aimed to ascertain the influence of various amounts (0-30%) of carrot puree (CP) in vegetable juice on linguapalatal swallowing pressure in healthy volunteers. Twenty healthy women (age range: 20-22 years) swallowed a 17-ml drink in a natural state, and linguapalatal swallowing pressure was measured using a special sensor sheet. Peak magnitude (maximum pressure of the tongue pushing on the hard palate), integrated values of linguapalatal swallowing pressure on the waveform, and duration of linguapalatal swallowing pressure were increased with increases in CP concentrations. The total integrated value for 30% CP vegetable juice was larger than that of vegetable juice with no CP. The apparent viscosity of the vegetable juice with a low CP concentration was smaller than that with a high CP concentration at the same shear rate. These results suggest that vegetable juice containing CP affects mechanoreceptor activity in the mouth and generates a neuromotor response. PRACTICAL APPLICATIONS: This study aimed to ascertain the influence of various amounts of carrot puree (CP) in vegetable juice on linguapalatal swallowing pressure measured by using a special sensor sheet in healthy volunteers. Obtained results of this study clearly showed that vegetable juice containing CP affects the movement of the tongue in maneuvering the bolus. Moreover, the results demonstrated that this effect depended on the concentration of CP in the vegetable juice. These findings are expected to provide clinically valuable data on the effect of mechanical stimulation during the oral stage of swallowing.

    To determine whether maximum bite force (MBF), an objective measure of oral function, is associated with development of frailty in community-dwelling older adults. This prospective cohort study included community-dwelling Japanese adults aged 75years at baseline (n=322). Baseline MBF was measured using an electronic recording device (Occlusal Force-Meter GM10). Follow-up examinations, including physical fitness and anthropometric evaluation and structured questionnaires, were administered annually over a 5-year period to determine the incidence of frailty, which was defined by the presence of 3 or more of the following 5 components derived from the Cardiovascular Health Study: low level of mobility, low physical activity level, weakness, shrinking and poor endurance and energy. Adjusted hazard ratios (HRs) of incidence of frailty according to sex-stratified tertiles of baseline MBF were calculated using Cox proportional hazards regression models. During the follow-up, 49 participants (15.2%) developed frailty. Participants in the lower tertile of MBF exhibited a significantly greater risk of frailty than those in the upper tertile. After adjustment for sex, depression, diabetes and Eichner index, the adjusted HRs for frailty in the upper through lower tertiles of MBF were 1.00 (reference), 1.27 (95% confidence interval [CI]: 0.50-3.20) and 2.78 (95% CI: 1.15-6.72), respectively (P for trend=.01). Poor oral function, as indicated by low MBF, increases the risk of development of frailty among elderly men and women.

    This research aimed to investigate the relationship between in vivo measurement of swallowing and sensory evaluation using thickened liquids as model foods. Healthy subjects (8 male and average 29.6-year old) participated in both tests, in which the subjects were asked to swallow the whole amount of sample (10 ml) at one time. In vivo measurement monitored thyroid cartilage movement during swallowing using a bendable pressure sensor synchronously with suprahyoid electromyography, whereas sensory evaluation measured perceived cohesiveness and adhesiveness on a visual analogue scale. Two variables from the pressure sensor analysis; activity of the thyroid cartilage and the maximum displacement of the thyroid cartilage were correlated negatively (p&lt;.01) to perceived cohesiveness with high correlation coefficient (vertical bar r vertical bar&gt; .9). Advantages of in vivo measurement over conventional shear rheology in assessing texture attributes perceived during swallowing were identified.
    Practical applications
    This research provides food manufactures with knowledge on a novel objective method for texture measurement of fluid foods and beverages based on human physiology during swallowing. Variable from this method can work as a measure for texture design of food products to meet consumers' preference, particularly foods for dysphagia patients whose demand is increasing in this aged society although subjects of study should be expanded to these people in the future.

    Swallowing is a very important and complex physiological behaviour. The dynamic of swallowing has created great interest as any procedural abnormality will result in dysphagia and even lower quality of life. However, a non-invasive evaluation of biomechanical coordination during oropharyngeal swallowing, which includes the activities of the tongue, the hyoid and swallowing-related muscles, has not yet been achieved. In the present study, we recruited fifteen subjects, and a non-invasive sensing system composed of a pressure sensor, a bend sensor, surface electrodes and a microphone was created to simultaneously monitor tongue pressure, hyoid motion, and surface EMG of swallowing-related muscles, as well as take sound recordings, when the subjects swallowed 5 ml of water. In addition to obtaining the durations of certain motor events, the considerable time (beginning, peak and ending time) of tongue pressure production, suprahyoid and infrahyoid muscle activity and hyoid motion were successfully measured. Moreover, the significant correlations between swallowing-related muscles, tongue pressure, and the hyoid were confirmed. These findings suggest that the non-invasive sensing system has potential as a good candidate for monitoring and evaluating the oropharyngeal process of swallowing, which may be useful in clinical work involving dysphagia evaluation and rehabilitation.

    There is some evidence to suggest that chewing gum reduces chronic stress. However, it remains controversial how the taste and odour properties of chewing gum influence stress. The present study was designed to investigate this issue in human subjects. Using an enzyme-linked immunosorbent assay, we tested salivary cortisol concentration, which is thought to be a stress marker, in 96 adults who chewed gum with different combinations of taste and odour. Subjects could discriminate between the types of gum without prior information. Salivary cortisol concentrations were highest and lowest for the subjects who chewed the most flavourful gum and the least flavourful gum, respectively. These findings suggest that the salivary cortisol level during gum chewing is not a marker of negative emotions (i.e., stressful conditions) as traditionally considered but, rather, an index of positive emotions that can facilitate biological responses to overcome stressful conditions.

    Stroke is considered one of the leading causes of death and acquired disability with a peak prevalence over the age of 80 years. Stroke may cause debilitating neurological deficiencies that frequently result in sensory deficits, motor impairment, muscular atrophy, cognitive deficits and psychosocial impairment. Oro-facial impairment may occur due to the frequent involvement of the cranial nerves' cortical representation areas, central nervous system pathways or motoneuron pools. The aim of this narrative, non-systematic review was to discuss the implications of stroke on oro-facial functions and oral health-related quality of life (OHRQoL). Stroke patients demonstrate an impaired masticatory performance, possibly due to reduced tongue forces and disturbed oral sensitivity. Furthermore, facial asymmetry is common, but mostly discrete and lip restraining forces are reduced. Bite force is not different between the ipsi- and contra-lesional side. In contrast, the contra-lesional handgrip strength and tongue-palate contact during swallowing are significantly impaired. OHRQoL is significantly reduced mainly because of the functional impairment. It can be concluded that impaired chewing efficiency, dysphagia, facial asymmetry, reduced lip force and OHRQoL are quantifiable symptoms of oro-facial impairment following a stroke. In the absence of functional rehabilitation, these symptoms seem not to improve. Furthermore, stroke affects the upper limb and the masseter muscle differently, both, at a functional and a morphological level. The rehabilitation of stroke survivors should, therefore, also seek to improve the strength and co-ordination of the oro-facial musculature. This would in turn help improve OHRQoL and the masticatory function, subsequently preventing weight loss and malnutrition.

    Objectives: An association between metabolic syndrome (MetS) and periodontal status has recently been focused on. However, no study has investigated the relationship between the prevalence of MetS and the decline of masticatory performance. We aimed to clarify the relationship between MetS and objective masticatory performance using the standardized test food in a general urban Japanese population.
    Methods: We studied 1780 Japanese men and women (mean age, 66.5 years) using the Suita study. MetS was defined using the uniform definition proposed in the 2009 Joint Interim Statement. Masticatory performance was evaluated by a chewing test using gummy jelly. Prevalence of MetS among quartiles of masticatory performance was compared using multiple logistic regression analysis adjusting for sex, age, drinking and smoking status, and periodontal status evaluated by the Community Periodontal Index.
    Results: Compared to the highest quartile of masticatory performance, the 2nd quartile showed a 1.46- fold increase in the prevalence of MetS (trend P = 0.159). In addition, Analysis by age showed 1.67-, 1.90- and 1.74-fold increases in the prevalence of MetS in the 3rd, 2nd and 1st quartiles among individuals in their 70s, respectively (trend P = 0.094). However, individuals in their 50s and 605 showed no significant relationship between masticatory performance and MetS.
    Conclusions: These findings suggested that masticatory performance are inversely associated with the prevalence of MetS independent of periodontal disease, especially in the elderly.
    Clinical significance: Declines in objective masticatory performance might be associated with the prevalence of MetS, independent of periodontitis. Given our results, treatments aimed at maintaining and recovering masticatory performance may represent important dental care to mitigate the risk of MetS. (C) 2016 Elsevier Ltd.

    Purpose: The Japan Prosthodontic Society (JPS) has proposed a new diagnostic nomenclature system (DNS), based on pathogenesis and etiology, to facilitate and improve prosthodontic treatment. This systemspecifies patient disability and the causative factor (i.e. "B (disability) caused by A (causative factor)''). The purpose of this study was to examine the reliability and validity of this DNS.
    Study selection: The JPS Clinical Guideline Committee assessed mock patient charts and formulated disease names using the new DNS. Fifty validators, comprising prosthodontic specialists and dental residents, made diagnoses using the same patient charts. Reliability was evaluated as the consistency of the disease names among the validators, and validity was evaluated using the concordance rate of the disease names with the reference disease names.
    Results: Krippendorff's a was 0.378 among all validators, 0.370 among prosthodontic specialists, and 0.401 among dental hospital residents. Krippendorff's alpha for 10 validators (3 specialists and 7 residents) with higher concordance rates was 0.524. Two validators (1 specialist and 1 resident) with the highest concordance rates had a Krippendorff's alpha of 0.648. Common disease names had higher concordance rates, while uncommon disease names showed lower concordance rates. These rates did not show correlation with clinical experience of the validator or time taken to devise the disease name.
    Conclusions: High reliability was not found among all validators; however, validators with higher concordance rates showed better reliability. Furthermore, common disease names had higher concordance rates. These findings indicate that the new DNS for prosthodontic dentistry exhibits clinically acceptable reliability and validity.

    Aim: A positive association between metabolic syndrome (MetS) and periodontal status has recently been noted. However, no study has evaluated the relationship by sex and in a general urban population using the uniform definition proposed in the 2009 Joint Interim Statement. The aim of this study was to clarify the relationship between MetS and periodontal status using the uniform definition in a general urban Japanese population.
    Methods: A total of 1,856 Japanese men and women (mean age: 66.4 years) were studied using data from the Suita study. Periodontal status was evaluated by the Community Periodontal Index (CPI). MetS was defined using the 2009 Joint Interim Statement. The associations of the MetS and its components with periodontal disease were investigated using multiple logistic regression analysis adjusting for age, drinking, and smoking.
    Results: Among the components of the MetS, low HDL cholesterol level was significantly associated with periodontal disease in men and women [odds ratios (OR) 2.39 and 1.53; 95% confidence intervals 1.36-4.19 and 1.06-2.19]. Furthermore, the risk of periodontal disease showed 1.43-, 1.42-, and 1.89-fold increases in those with 2, 3, and &gt;= 4 components, respectively, compared with those having no components (P-trend &lt; 0.001). For the analysis by sex, the risk of periodontal disease was increased 2.27- and 1.76-fold in those with &gt;= 4 components in men and women, respectively (both P-trend= 0.001).
    Conclusion: These findings suggest that MetS and lower HDL cholesterol are associated with periodontal disease. Subjects with two or more MetS components had a significantly higher prevalence of periodontal disease.

    There is limited information on the impact of oral function on mortality among older adults. The aim of this prospective cohort study was to examine whether an objective measure of oral function, maximum bite force (MBF), is associated with mortality in older adults during a 13-year follow-up period. Five hundred and fifty-nine community-dwelling Japanese (282 men and 277 women) aged 70 years at baseline were included in the study. Medical and dental examinations and a questionnaire survey were conducted at baseline. Maximum bite force was measured using an electronic recording device (Occlusal Force-Meter GM10). Follow-up investigation to ascertain vital status was conducted 13 years after baseline examinations. Survival rates among MBF tertiles were compared using Cox proportional hazards regression models stratified by sex. There were a total of 111 deaths (82 events for men and 29 for women). Univariable analysis revealed that male participants in the lower MBF tertile had increased risk of all-cause mortality [hazard ratio (HR) = 1.94, 95% confidence interval (CI) = 1.13-3.34] compared with those in the upper MBF tertile. This association remained significant after adjustment for confounders (adjusted HR = 1.84, 95% CI = 1.07-3.19). Conversely, no association between MBF and all-cause mortality was observed in female participants. Maximum bite force was independently associated with all-cause mortality in older Japanese male adults. These data provide additional evidence for the association between oral function and geriatric health.

    Purpose:' The aim of this study was to reveal whether the differences in further loss of teeth and occlusal supports, and change in masticatory ability depend on the status of dentition at the age of 70 in community-dwelling elderly people.
    Methods: A 10-year longitudinal survey was carried out on 349 (176 females and 173 males) elderly subjects. The subjects to be analyzed were classified into four groups in accordance with the classifications of Miyachi's Triangular Classification. Zone A: subjects with ten or more occlusal supports. Zone B: those with nine to five occlusal supports. Zone D: those with four or fewer occlusal supports and 11 or more remaining teeth. Zone C: those with ten or fewer remaining teeth. The numbers of remaining teeth and occlusal supports were recorded in both examinations. Questionnaires regarding their food intake status were given to subjects.
    Results: Subjects in Zone B had greater numbers of teeth loss than those in Zones A and C. Subjects in Zone B and D lost greater numbers of occlusal supports than subjects in Zones A and C. The number of food items that could be chewed had significantly decreased in subjects who remained in Zone A and those who changed from Zone B to Zones D and C.
    Conclusions: It was shown that various states of dentition classified by Miyachi's Triangular Classification at the age of 70 resulted in different numbers of remaining teeth and occlusal supports and changes in masticatory ability 10 years later in community-dwelling elderly people.

    Although diver's mouth syndrome (DMS) has long been recognized by scuba divers, little attention has been paid to the influence of wearing a scuba diving mouthpiece on the stomatognathic system. In this review, DMS-related stomatognathic events (DMS-SE) while wearing a mouthpiece, the relationship between components of the mouthpiece and those events, and design considerations to reduce the risk of those events are discussed based on evidence from 32 articles concerning scuba diving mouthpieces. Forward movement of the mandible, loss of molar occlusal support, and continuous jaw clenching while wearing a mouthpiece are considered to be pathogenic for DMS-SE. Several experimental studies have suggested a relationship between incidence of those events and the design of mouthpiece components such as the connector, labial flange, platform, and occlusal rug, and the possibility of reducing risk of those events through design customization of these components. Improvement of the shape of commercially available mouthpieces and creation of custommade mouthpieces may thus contribute to the prevention and treatment of DMS-SE and the provision of a comfortable diving environment.

    The supratrigeminal nucleus (Vsup), originally proposed as a premotoneuron pool in the trigeminal reflex arc, is a key structure of jaw movement control. Surprisingly, however, the location of the rat Vsup has not precisely been defined. In light of our previous cat studies, we made two hypotheses regarding the rat Vsup: (1) the Vsup is cytoarchitectonically distinguishable from its surrounding structures; (2) the Vsup receives central axon terminals of the trigeminal mesencephalic nucleus (Vmes) neurons which are primary afferents innervating muscle spindles of jaw-closing muscles and periodontal ligaments around the teeth. To test the first hypothesis, we examined the cytoarchitecture of the rat Vsup. The Vsup was identified as an area medially adjacent to the dorsomedial part of trigeminal principal sensory nucleus (Vp), and extended from the level just rostral to the caudal two-thirds of the trigeminal motor nucleus (Vmo) to the level approximately 150 mu m caudal to the Vmo. Our rat Vsup was much smaller and its location was considerably different in comparison to the Vsup reported previously. To evaluate the second hypothesis, we tested the distribution patterns of Vmes primary afferent terminals in the cytoarchitectonically identified Vsup. After transganglionic tracer applications to the masseter, deep temporal, and medial pterygoid nerves, a large number of axon terminals were observed in all parts of Vsup (especially in its medial part). After applications to the inferior alveolar, infraorbital, and lingual nerves, a small number of axon terminals were labeled in the caudolateral Vsup. The Vsup could also be identified electrophysiologically. After electrical stimulation of the masseter nerve, evoked potentials with slow negative component were isolated only in the Vsup. The present findings suggest that the rat Vsup can be cytoarchitectonically and electrophysiologically identified, receives somatotopic termination of the trigeminal primary afferents, and principally receives strong termination of the spindle Vmes primary afferents.

    著者らは、これまでグミゼリーを用いた咀嚼能率の客観的な評価システムを開発し、臨床研究や疫学研究における有用性を確認してきた。しかし、咀嚼能力が低下した者においては、30回の咀嚼でグミゼリーを咬断できない場合があり、個人内や個人間の咀嚼能率の差を判定することが困難になることがあった。そこで、著者らは半量グミゼリーを用いて咀嚼能率を評価する新しい視覚的判定法(咀嚼能率スコア法)を開発した。まず、あらかじめ4種類に分割した半量グミゼリーの表面積増加量を、著者らの開発した全自動咀嚼能力解析装置の発光ダイオードで測定した受光部電圧値から計算するための理論式を確立した。次に、全量グミゼリーの咀嚼能率スコアが0か1である31名の高齢者において、半量グミゼリーを30回咀嚼後の咬断片表面積増加量が0〜1200mm2に分布することを確認した。これらの結果をもとに、最終的に各スコアに対応した咬断片の写真を撮影し、8段階の咀嚼能率スコア法を作成し、半量グミゼリーの咬断片表面積増加量0〜1750mm2の範囲を評価することとした。本法は、咀嚼障害をもつ要介護高齢者や義歯装着者の咀嚼能率を評価する上で、有用であると期待される。(著者抄録)

    Previous studies have identified various factors related to masticatory performance. This study was aimed to investigate variations and impacts of factors related to masticatory performance among different occlusal support areas in general urban population in Japan. A total of 1875 Japanese subjects (mean age: 667 years) were included in the Suita study. Periodontal status was evaluated using the Community Periodontal Index (CPI). The number of functional teeth and occlusal support areas (OSA) were recorded, and the latter divided into three categories of perfect, decreased and lost OSA based on the Eichner Index. Masticatory performance was determined by means of test gummy jelly. For denture wearers, masticatory performance was measured with the dentures in place. The multiple linear regression analysis showed that, when controlling for other variables, masticatory performance was significantly associated with sex, number of functional teeth, maximum bite force and periodontal status in perfect OSA. Masticatory performance was significantly associated with number of functional teeth, maximum bite force and periodontal status in decreased OSA. In lost OSA, masticatory performance was significantly associated with maximum bite force. Maximum bite force was a factor significantly influencing masticatory performance that was common to all OSA groups. After controlling for possible confounding factors, the number of functional teeth and periodontal status were common factors in the perfect and decreased OSA groups, and only sex was significant in the perfect OSA group. These findings may help in providing dietary guidance to elderly people with tooth loss or periodontal disease.

    Abnormalities of swallowing in patients with mandibular prognathism have not been evaluated quantitatively. The aim of this study was to compare tongue pressure production for bolus transfer between volunteers with normal occlusion and patients with mandibular prognathism. The control group had 10 female volunteers with normal occlusion, and the patient group had 10 women with mandibular prognathism. Tongue pressure was measured by a palatal sensor sheet at five sites on swallowing 4 mL of a tasteless and odourless jelly. Results: The tongue pressure waveform differed between the control and patient groups. The incidence of a double-peak tongue pressure waveform was more frequent in the patient group. In both groups, the exertion of tongue pressure began at the anterior point of the sensor sheet, followed by the peripheral parts. Although the order of expression of tongue pressure was the same for the two groups, maximum tongue pressure at all parts of the sensor sheet was lower in the patient group than in the control group. Furthermore, swallowing time was longer in the patient group than in the control group at the peripheral parts of the palate. These results clearly show the difference in tongue pressure production during swallowing between patients with mandibular prognathism and volunteers with normal occlusion. The current findings suggest that maxillofacial morphology may affect tongue movement during swallowing.

    高齢者の咀嚼能力を客観的に評価することは、健康状態や提供する食事の内容を検討するうえで重要である。本研究は、通所介護施設を利用する高齢者34名(男性13名、女性21名、平均年齢85.4歳、介護認定の中央値:要介護2)を対象に、検査用グミゼリーを用いた咀嚼能率測定(スコア法、グルコース濃度測定法)を行い、既存の評価法である簡易咬合力測定や摂取可能食品アンケート調査と比較し、その有用性を検討した。咀嚼能率測定は、すべての被験者において遂行可能であり、スコア法において咬断片のばらつきを補正することにより、咀嚼能率スコア値が手動法におけるグルコース溶出量と高い相関を示した。咬合力や介護度との間にも有意相関が示された(p<0.05)。グミゼリーをほとんど咬断できずスコア法ではスコア0と判定された被験者においても、手動法におけるグルコース溶出量によってより詳細な評価が可能であった。摂取可能食品アンケートによる評価は、ほとんどの対象者に対して質問者が付き添う必要があり、理解力の低下のため時間を要し、多くの被験者において咀嚼能率測定の結果と乖離がみられた。以上より、検査用グミゼリーによる咀嚼能率測定法は、簡便かつ測定者ならびに被験者の負担も少ないことから、要介護高齢者においても有用であることが示唆された。(著者抄録)

    【目的】咀嚼・嚥下機能の低下した高齢者にとって、食塊の嚥下は生死を分ける大きな問題となる場合があり、これは社会的課題である。食塊を安全に嚥下するためには、食品の物理的性質が大きく影響する。本報告では、嚥下特性およびテクスチャー特性、咽頭部での食塊の移動特性を測定して検討した。 【方法】試料には0.1~0.9%破砕寒天ゾルを用い、被験者は20~22歳の女子学生とした。嚥下時の舌圧と咽頭部における食塊の移動速度を測定し、機器と官能評価によるテクスチャー特性値を測定した。 【結果】テクスチャーの客観測定と主観測定から、寒天濃度は高くなるほど付着性は高くなった。客観測定において、0.3%試料の付着性が0.5~0.9%試料よりも低く、主観評価では03%試料の付着性は0.7および0.9%試料よりも低いと評価された。嚥下時の舌と硬口蓋との接触時間およびピーク値は、0.7および0.9%試料は0および0.1%試料よりも長く、大きかった。硬口蓋正中後部において、嚥下時の舌と硬口蓋の初期接触時間は寒天濃度が高いほど遅かった。咽頭部における食塊の最大移動速度は、寒天濃度が高くなると低下した。これらの結果は、寒天の濃度が高くなると、嚥下時に食塊を口腔から咽頭部へ移送するための舌と硬口蓋の接触エネルギーは高くなるが、咽頭部における食塊の移動速度は反対に低下する関係であった。0.5%は0.7および0.9%試料に比較して、舌と硬口蓋の接触時のピーク値が小さく、嚥下しやすいと評価され、咽頭部における食塊の移動速度は中程度であった。これらの結果から、安全な飲み込みの寒天濃度は、本実験で使用した試料中では0.5%前後ではないかと考えられた。<b></b>

    The aim of this study was to record oral vestibule pressure (OVP) by the lip and cheek contraction during gum chewing, to examine the characteristics of these pressures and coordination between the OVP and jaw movement. The subjects were eight healthy adult men (mean age of 29.3 +/- 3.3 years). An experimental plate that incorporated four pressure sensors on the midline of the upper jaw (Ch. 1), upper right canine (Ch. 2), upper right first molar (Ch. 3) and upper left first molar (Ch. 4) was used for measuring OVP. The right masseter electromyogram (EMG) was recorded simultaneously. Subjects chewed gum on the right side 20 times, and eight consecutive strokes were used for the analysis of the sequential order, maximal magnitude and duration of each OVP. Onset of OVP was observed at the molar on the non-chewing side (Ch. 4) before chewing side (Ch. 3), and offset was largely simultaneous at each site. On the chewing side (Chs. 1-3), OVP onset during the interval of EMG activity reached to the peak around the end of interval and offset in the duration of EMG activity. The maximal pressure was significantly larger at Chs. 1-3 than at Ch. 4, but no significant differences were observed in duration of pressure among each site. These results suggest that OVP is coordinated with jaw movement during gum chewing, and larger pressure is produced on the chewing side than on the non-chewing side. Our findings are quantitative indices for the evaluation of lip and cheek function during mastication.

    Background and objectiveMany stroke patients may have oral problems and systemic diseases, but clinical information on treatment provided to stroke patients for dental problems during inpatient rehabilitation is rare. The objective of this study was to research stroke inpatients' requirements for dental treatment and the accompanying risks.
    MethodsWe included 165 stroke patients undergoing inpatient rehabilitation at Morinomiya Hospital during the year 2010 and researched the causes of stroke and the patients' orodental status, underlying diseases, antithrombotic drugs prescribed and special considerations or difficulties in the treatment.
    ResultsCerebral infarction was the most common causes of stroke. Many patients had hypertension, heart disease or diabetes mellitus, and 54.5% had been prescribed antithrombotic drugs. Dentists diagnosed 57.0% patients with untreated dental cavities. Approximately 30% did not use dentures despite having a requirement. In total, 142 patients underwent dental treatment including periodontal treatment, prosthetic treatment and tooth extraction under management of circulation and haemostasis such as monitoring vital signs and surgical splints in cases of the difficult extraction.
    ConclusionThe current study revealed a high requirement for dental treatment among stroke patients and demonstrated the effectiveness of performing dental treatment during inpatient rehabilitation of these patients.

    In swallowing, the tongue contacts against the hard palate to generate pressure for propelling a bolus from the oral cavity into the pharynx. Meanwhile, the hyoid and larynx move upward and forward to facilitate the bolus from the pharynx into the esophagus. It has been well known that sequential coordination between those actions is critical for safety accomplishment of swallowing. However, the absence of noninvasive assessment for it limits the detection to the physiological symptom of dysphagia. We applied a sensor sheet on the hard palate to measure tongue contact pressure and a bend sensor on the frontal neck to monitor the laryngeal movement, which was synchronized with hyoid motion for assessing the coordination between both actions in 14 healthy male subjects when swallowing 5 ml of water. The sequential order of tongue pressure and hyoid movement was successfully displayed. Tongue pressure was produced after slight movement of the hyoid and closely to the hyoid elevation, then reached a maximum when the hyoid stabilized in the most anterior superior position, and ceased concurrently with the onset of hyoid descent. Additionally, the synchronized data from both sensors showed positive correlations between identified time points on the laryngeal signal waveform and onset, peak and offset of tongue pressure. Our sensing system successfully showed the coordination between tongue pressure production and hyoid motion, and could be a simple and noninvasive method for clinicians to evaluate the oral and pharyngeal stages of swallowing.

    Relationship between throat sensations of beverages and some parameters from two types of in vivo measurements of swallowing was investigated. It was indicated using carbonated water that sparkling sensation can be assessed by the acoustic analysis of the swallowing sound, where both the intensity and the occurrence of the sound detected at a particular frequency of 4.0kHz during the bolus flow through the pharynx were increased by sparkling sensation. It was also indicated using beer that bodying sensation can be assessed by the kinetic analysis of the laryngeal movement, where both the duration and the activity of the larynx required for one swallowing cycle and detected on a bend sensor were increased by bodying sensation. Furthermore, it was demonstrated by these in vivo measurements that human swallowing behavior can be modified by the addition of flavor compounds, which was sometimes accompanied with enhanced perception in each sensation.
    Practical ApplicationsConsumers' palatability is becoming more diverse not only in solid or semi-solid foods but also liquid foods such as beverages. In the development of beverage products, including soft drinks and beers, throat sensations perceived during drinking should be designed proficiently because they can greatly impact the consumers' preference. Although the design of throat sensation of beverage products can be the key for the commercial success, the industry is still looking for any suitable measurement to quantify these human perceptions in an objective, reproducible and easy manner. Evaluation protocol established in the present study meets these requirements and should contribute to the development of high-value added products. In this aged society, usage of the protocol can be expanded to the development of beverage products for dysphagia patients in terms of prevented misleading, for example.

    Aim: Contact of the tongue against the hard palate plays an important role in swallowing. Therefore, age-related decline in tongue function has received much attention. The purpose of the present study was to investigate the effect of complete denture wearing on tongue motor biomechanics during swallowing in healthy edentulous older adults.
    Methods: A total of 19 edentulous patients (6 males and 13 females, mean age 76.2 +/- 7.2 years) without any history of neuromuscular disease or dysphagia were selected. All patients were wearing complete dentures in both the upper and lower jaws. Tongue pressure against the hard palate during swallowing saliva was recorded using an original T-shaped sensor sheet with five measuring points. Measurements were carried out both with and without the prostheses. For evaluating swallowing ability, the frequency of swallowing saliva in 30 s was recorded (Repetitive Saliva Swallowing Test).
    Results: With the prostheses, the maximal magnitude and duration of tongue pressure was larger at Ch. 1 (anterior-median part of the hard palate) and Ch. 2 (mid-median part) right and left circumferential parts than without the prostheses. As for the integral of tongue pressure, that with prostheses was larger at all 5 channels than that without prostheses. There was significant improvement in the Repetitive Saliva Swallowing Test value while wearing prostheses.
    Conclusions: These results suggested that swallowing function deteriorated as a result of the decline in tongue-palate contact on removing complete dentures in edentulous older adults.
    Clinical relevance: The present study showed the effect of wearing prostheses on swallowing in edentulous older adults.

    Dysphagic patients are fed soft meals made of gels and process them by squeezing the food with the tongue, which reduces food size. Although the gels are designed based on rheological analyses, the impact of the initial gel texture on tongue kinetics is not known. This study investigated the effect of gel consistency on tongue pressure during squeezing and swallowing and compared results of the mechanical analyses. Fifteen healthy young subjects participated in this study. Tongue pressure during squeezing and swallowing was measured by a sensor sheet with five measuring points. Five ml of water and six gel samples prepared using two gelling agents at three concentrations each were used as test materials. Subjects were instructed not to chew the food but to squeeze it using their tongue. The shape of the tongue pressure waveform during the initial squeeze was similar to the stresse-time curve using a texture analyzer. However, the sequential order of tongue pressure during squeezing and swallowing was different. Tongue pressure during the initial squeeze was affected by gel consistency. The amplitude of tongue pressure during swallowing increased as gel consistency increased, but the duration of pressure was not affected. The slopes of tongue pressure generation were not affected by gel consistency, although the mechanical measurements showed increases in these slopes with increasing gel consistency. These results suggest that findings regarding characteristics of tongue movement during squeezing and textural properties of gels might be useful for food design and clarification of oral physiology.

    There are numerous reports on the relationship between regular utilization of dental care services and oral health, but most are based on questionnaires and subjective evaluation. Few have objectively evaluated masticatory performance and its relationship to utilization of dental care services. The purpose of this study was to identify the effect of regular utilization of dental services on masticatory performance. The subjects consisted of 1804 general residents of Suita City, Osaka Prefecture (760 men and 1044 women, mean age 66.5 ± 7.9 years). Regular utilization of dental services and oral hygiene habits (frequency of toothbrushing and use of interdental aids) was surveyed, and periodontal status, occlusal support, and masticatory performance were measured. Masticatory performance was evaluated by a chewing test using gummy jelly. The correlation between age, sex, regular dental utilization, oral hygiene habits, periodontal status or occlusal support, and masticatory performance was analyzed using Spearman's correlation test and t-test. In addition, multiple linear regression analysis was carried out to investigate the relationship of regular dental utilization with masticatory performance after controlling for other factors. Masticatory performance was significantly correlated to age when using Spearman's correlation test, and to regular dental utilization, periodontal status, or occlusal support with t-test. Multiple linear regression analysis showed that regular utilization of dental services was significantly related to masticatory performance even after adjusting for age, sex, oral hygiene habits, periodontal status, and occlusal support (standardized partial regression coefficient β = 0.055). These findings suggested that the regular utilization of dental care services is an important factor influencing masticatory performance in a Japanese urban population.

    The objectives of this study were to evaluate the state of tongue pressure production during supraglottic swallow (SS) and super-supraglottic swallow (SSS) performed by healthy adults, and to investigate the effects of these swallowing maneuvers on the oral stage of swallowing. The participants were 19 healthy individuals. Tongue pressure against the hard palate during swallowing was measured using a tongue pressure sensor sheet system with five pressure-sensitive points. The tasks comprised swallowing 5 mL of water by normal wet swallow, SS, and SSS, and the parameters for analysis were the duration, the maximal magnitude, and the integrated value of tongue pressure during swallowing. The duration of tongue pressure was significantly longer at the anterior-median part of the hard palate during both SS and SSS than with normal wet swallow. The maximal magnitude increased significantly only at the posterior part of the hard palate during SS, but at all points during SSS. The integrated value increased significantly only at the posterior-median part of the hard palate during SS, but at all points except the mid-median part of the hard palate during SSS. The maximal magnitude and integrated value were also significantly higher at the anterior-median and posterior circumferential parts during SSS than during SS. These results show that these two swallowing maneuvers, which are known primarily as techniques to protect the airway, also function to strengthen the tongue pressure produced by the contact between the tongue and the hard palate during swallowing and this effect is more pronounced during SSS.

    Instrumental compression test using artificial tongue was carried out to compare the fracture profile of gels with the first oral strategy for size reduction by humans (termed as the first size reduction). Gellan gel samples, whose size and shape were the same as those of artificial tongue, were prepared in a wide mechanical range and were compressed uniaxially on artificial tongue at crosshead speed of 10 mm/s. When apparent Young's modulus of artificial tongue was approximately 55 kPa, fracture probability of gels corresponded to the ratio of subjects who decided to use tongue-palate compression instead of mastication. This was applicable to the gels whose fracture strain was below 65% but not to the gels whose fracture strain was above 70% within the range of fracture stress tested; approximately 30-100 kPa. Fracture strain should be a critical initial mechanical parameter that relates to the decision of oral strategy.

    In individuals with Down syndrome, hypotonicity of the tongue and an underdeveloped maxilla may lead to poor oral motor coordination, which adversely affects the oral phase of swallowing. This study aimed to evaluate the characteristics of pressure produced by the tongue against the hard palate during swallowing in individuals with Down syndrome. In addition, the relationship between tongue pressure and palatal morphology was examined. We studied nine adults with Down syndrome and ten healthy adults as controls. Tongue pressure while swallowing 5 mL water was recorded by a sensor sheet system with five measuring points attached to the hard palate. Palatal length, depth, width, curvature, and slope were measured by three-dimensional digital maxillary imaging. The order of onset of tongue pressure on the median line of the hard palate was the same in all participants, except for three with Down syndrome. The duration and maximal magnitude of tongue pressure on the median line in nine participants with Down syndrome were significantly shorter and lower than those of controls. In participants with Down syndrome, significant positive correlations were observed between the duration of tongue pressure at the mid-median part of the hard palate and palatal depth and width, and between the duration and maximal magnitude of tongue pressure at the posterior-median part and palatal length. These findings suggest that impaired tongue activity, poor tongue control, and constrained tongue motion due to a short and narrow palate contribute to swallowing difficulty in individuals with Down syndrome.

    Although dysphagia is a life-threatening problem in patients with Duchenne muscular dystrophy (DMD), the pathophysiology of oral stage dysphagia is yet to be understood. The present study investigated the tongue motor deficit during swallowing in patients with DMD and its relationship with disease-specific palatal morphology. Tongue pressure during swallowing water was recorded in 11 male patients with DMD and 11 age- and sex-matched healthy subjects using an intra-oral sensor with five measuring points, and the state of tongue pressure production was compared between the groups. Palatal morphology was assessed by a non-contact three-dimensional scanner on maxillary plaster models. In patients with DMD, the normal sequential order of tongue-palate contact was lost and the maximal magnitude and integrated value of tongue pressure on the mid-anterior part of palate were smaller than those in healthy subjects. The width of the palate in patients was greater than that in healthy subjects and the depth of the palate in patients had a negative correlation with tongue pressure magnitude on the median palate. Our results suggested that the deteriorated tongue motor kinetics prevented tongue movement during swallowing that was appropriate for the depth of the palate and affects the state of tongue pressure production during swallowing.

    This study assessed the relationship between different oral health markersuperiodontitis, gingival bleeding, tooth number, and occlusal statusuand hypertension in a Japanese urban population.
    A total of 1,643 participants with no prior cardiovascular disease (mean age 66.6 years; 43.4% women) underwent comprehensive health checkups, including a lifestyle questionnaire and dental examination in the Suita Study.
    In the multivariable-adjusted logistic model, none of the individual oral health markers, namely severe periodontitis, gingival bleeding, lowest quartile of tooth number, and malocclusion, were significantly associated with increased odds of hypertension. The additive effects of oral health markers on hypertension were examined and showed that, compared with subjects with no component of the oral health markers, the multivariale-adjusted odds ratio of hypertension in those with 3 components was 1.82 (95% confidence interval (CI) 1.232.72; P 0.003). In the subpopulation without antihypertensive medication (n 1,148; 59.8% women), a significant graded relationship between multivariable-adjusted systolic blood pressure and the number of components was found (P-trend 0.03), and, compared with subjects with no component of the oral health markers, having 3 components was related to a higher systolic blood pressure ( 5.41; 95% CI 1.169.66; P 0.01).
    There is an additive relationship between oral health disorders and risk of hypertension. Our results suggest that the existence of moderate or severe oral health disordersuthat is, several concomitant oral health disordersuis associated with risk of hypertension.

    Aim
    In this study, we investigated the effect of differences in periodontal status in the masticatory performance of dentate subjects with the same occlusal supporting area.
    Materials and Methods
    The subjects of the analysis were classified into those of Eichner A1-3 (n=1094) and Eichner B1-4 (n=529). Subjects' periodontal status was evaluated on the basis of the Community Periodontal Index (CPI). The number of functional teeth and occlusal support were investigated, the latter on the basis of the Eichner Index. Furthermore, masticatory performance was investigated by means of test gummy jelly. For each group, periodontal status was classified in two different ways, either with/without moderate periodontitis (CPI Code &lt;= 2/&gt;= 3) or with/without severe periodontitis (CPI Code &lt;= 3/4), and masticatory performance was compared between the various groups.
    Results
    In subjects who were Eichner A1 and B3, masticatory performance was significantly lower in subjects with moderate periodontitis compared with those without, and in subjects with severe periodontitis compared with those without.
    Conclusion
    Periodontal disease affects masticatory performance not only if occlusion is established by natural dentition with no tooth loss but also if occlusal support has decreased.

    This position paper reviews physical and mechanical properties of thermoplastic resin used for non-metal clasp dentures, and describes feature of each thermoplastic resin in clinical application of non-metal clasp dentures and complications based on clinical experience of expert panels. Since products of thermoplastic resin have great variability in physical and mechanical properties, clinicians should utilize them with careful consideration of the specific properties of each product. In general, thermoplastic resin has lower color-stability and higher risk for fracture than polymethyl methacrylate. Additionally, the surface of thermoplastic resin becomes roughened more easily than polymethyl methacrylate. Studies related to material properties of thermoplastic resin, treatment efficacy and follow-up are insufficient to provide definitive conclusions at this time. Therefore, this position paper should be revised based on future studies and a clinical guideline should be provided.

    OBJECTIVE: To evaluate the effects of the application of tongue pressure sensor sheet on the signal waveform of laryngeal movement produced by the bend sensor during deglutition. METHODS: Twelve adult male subjects were recruited to perform a single swallow of 5 ml water when sitting on the dental chair with upright position. The data recorded by bend sensor was obtained with attaching tongue pressure sensor sheet simultaneously or not. Then the measured parameters by bend sensor with or without concurrent application of tongue pressure sensor sheet were compared. RESULTS: There were no significant differences between the same time point on the signal waveform produced by bend sensor whether concurrently attaching tongue pressure sensor sheet or not (P &gt; 0.05). Additionally, we found no statistical significances between matched phases on the signal waveform recorded by bend sensor with or without application of tongue pressure sensor sheet (P &gt; 0.05). CONCLUSION: The findings in this study suggest us that the usage of tongue pressure sensor sheet exerted no influences on the waveform of the laryngeal movement produced by bend sensor during deglutition, facilitating us to further a

    Background: In the recent hyper-aged societies of developed countries, the market for soft diets for patients with dysphagia has been growing and numerous jelly-type foods have become available. However, interrelationships between the biomechanics of oral strategies and jelly texture remain unclear. The present study investigated the influence of the initial consistency of jelly on tongue motor kinetics in different oral strategies by measuring tongue pressure against the hard palate.
    Methods: Jellies created as a mixture of deacylated gellan gum and psyllium seed gum with different initial consistencies (hard, medium or soft) were prepared as test foods. Tongue pressure production while ingesting 5 ml of jelly using different oral strategies (Squeezing or Mastication) was recorded in eight healthy volunteers using an ultra-thin sensor sheet system. Maximal magnitude, duration and total integrated values (tongue work) of tongue pressure for size reduction and swallowing in each strategy were compared among initial consistencies of jelly, and between Squeezing and Mastication.
    Results: In Squeezing, the tongue performed more work for size reduction with increasing initial consistency of jelly by modulating both the magnitude and duration of tongue pressure over a wide area of hard palate, but tongue work for swallowing increased at the posterior-median and circumferential parts by modulating only the magnitude of tongue pressure. Conversely, in Mastication, the tongue performed more work for size reduction with increasing initial consistency of jelly by modulating both magnitude and duration of tongue pressure mainly at the posterior part of the hard palate, but tongue work as well as other tongue pressure parameters for swallowing showed no differences by type of jelly.
    Conclusions: These results reveal fine modulations in tongue-palate contact according to the initial consistency of jelly and oral strategies.

    This study aimed to investigate the influence of carbonated drinks with gas volumes (GV) of 0, 1.5, and 2.7 on linguapalatal swallowing pressure, intraoral carbonation perception, and maximum velocity of a bolus through the pharynx in healthy volunteers (N 20, all female, age range; 2021 years). The volunteers swallowed a 12-mL drink in the natural state. Linguapalatal swallowing pressure was measured using a special sensor sheet, and maximum velocity of the bolus through the pharynx was measured using ultrasonic diagnostic imaging equipment. Peak magnitude, integrated value, and duration of linguapalatal swallowing pressure and maximum velocity of a liquid bolus through the pharynx increased with an increase in carbon dioxide content in the carbonated drink. The total integrated values of carbonated drinks with GV of 1.5 and 2.7 were larger than that of the drink without carbon dioxide. These results suggest that the carbon dioxide dissolved in carbonated drinks influences the activity of taste receptors in the mouth and results in neuromotor responses.

    Tongue-hold swallow (THS) has the potential to be a resistance exercise not only for the pharyngeal constrictor but for the tongue muscles. To elucidate the physiological mechanisms of THS, this study investigated intraoral pressure generation during THS in relation to different extents of tongue protrusion. Tongue pressure was measured by a 5-point pressure sensor sheet placed onto the hard palate of 18 healthy young subjects who performed three swallow tasks: normal dry swallow, THS with slight tongue protrusion, and THS with greater tongue protrusion. Subjects randomly repeated each task five times. Maximum range of tongue protrusion was also measured in each subject to estimate lingual flexibility. With an increase in the extent of tongue protrusion, pressure generation patterns became irregular and variable. Duration of pressure generation increased with statistical significance in the posterior circumferential parts of the hard palate (p &lt; 0.05). Maximal magnitude and integrated value of the pressure recorded at these locations increased in eight subjects as the extent of tongue protrusion increased, but it decreased in nine. The former group showed greater lingual flexibility, while the latter group exhibited less flexibility. THS may place different amounts of load on the tongue muscles by adjusting the degree of tongue protrusion.

    This position paper proposes a definition and naming standard for removable partial dentures (RPDs) using thermoplastic resin, and presents a guideline for clinical application. A panel of 14 experts having broad experience with clinical application of RPDs using thermoplastic resin was selected from members of the Japan Prosthodontic Society. At a meeting of the panel, "non-metal clasp denture" was referred as the generic name of RPDs with retentive elements (resin clasps) made of thermoplastic resin. The panel classified nonmetal clasp dentures into two types: one with a flexible structure that lacks a metal framework and the other having a rigid structure that includes a metal framework. According to current prosthetic principles, flexible non-metal clasp dentures are not recommended as definitive dentures, except for limited cases such as patients with a metal allergy. Rigid non-metal clasp dentures are recommended in cases where patients will not accept metal clasps for esthetic reasons. Non-metal clasp dentures should follow the same design principles as conventional RPDs using metal clasps. (C) 2013 Japan Prosthodontic Society. Published by Elsevier Ireland. All rights reserved.

    The aim of this study was to investigate oropharyngeal pressure flow dynamics during dry swallowing in ten healthy subjects. Tongue pressure (TP) was measured using a sensor sheet system with five measuring points on the hard palate, and pharyngeal pressure (PP) was measured using a manometric catheter with four measuring points. The order and correlations of sequential events, such as onset, peak, and offset times of pressure production, at each pressure measuring point were analyzed on the synchronized waveforms. Onset of TP was earlier than that of PP. The peak of TP did not show significant differences with the onset of PP, and it was earlier than that of PP. There was no significant difference between the offset of TP and PP. The onset of PP was temporally time-locked to the peak of TP, and there was an especially strong correlation between the onset of PP and TP at the posterior-median part on the hard palate. The offset of PP was temporally time-locked to that of TP. These results could be interpreted as providing an explanation for the generation of oropharyngeal pressure flow to ensure efficient bolus transport and safe swallowing.

The integrated value of tongue pressure at the posterior-circumferential parts in the Mendelsohn maneuver and at the median parts in the effortful swallow showed a tendency to increase. These results suggest that tongue pressure increases along a wide part of the hard palate in effortful swallow because the anchor of tongue movement is emphasized at the anterior part of the hard palate. The Mendelsohn maneuver provides prolonged and accentuated tongue-palate contact at the posterior-circumferential parts, which might be important for hyoid-laryngeal elevation during swallowing.

    The tongue is important for orofacial movements, including swallowing. Although numerous studies have focused on tongue pressure against the palate, its physiological role has not been fully evaluated. The tongue pressure generation may have the temporal coordination with the swallowing relational organs. The aim of this study was to clarify the physiological mechanisms of tongue pressure and to investigate the temporal relationship among tongue pressure, supra-hyoid muscle activity, and videofluorographic (VF) images during swallowing. Fifteen healthy young subjects participated. Tongue pressure measured using a sensor sheet with five channels, electromyographic EMG, and VF was recorded synchronously during 4-ml barium swallowing. Swallowing behavior in VF images with and without the sensor sheet was compared. Furthermore, the temporal relationship between events measured from tongue pressure, EMG, and VF was evaluated. Swallowing behavior on VF images was not affected by placement of the sensor sheet. Tongue pressure at the posterio-lateral point of the hard palate tended to have biphasic peaks. Tongue pressure production with a monophasic pattern appeared during the same period as the second peak in the biphasic pattern. The onset of tongue pressure was later than the start of hyoid movement and onset of EMG, and offset was observed between the hyoid at the up-forward position and reposition. Onset of tongue pressure at the anterior area was correlated with the start of slight hyoid elevation. Offset of tongue pressure at the posterio-lateral points was strongly time locked with the hyoid at the up-forward position. The present results suggested the temporal coordination of tongue pressure generation with the swallowing-related organs. That is, the tongue pressure was produced for bolus propulsion, and was closely related to hyoid movement temporally during swallowing. These results may contribute to clarify the clinical state with the disorder of tongue kinetics.

    Purpose: Although a closed hollow obturator is often applied to post maxillectomy patients, it has a few problems such as complexity of fabrication and water leakage to inside. A one step curing technique to fabricate a closed hollow obturator by constructing a small hollow bulb made by two thermoplastic resin sheets is described in the present report.
    Methods: In the one step curing technique, after dewaxing the wax denture fabricated conventionally, one size smaller hollow body was fabricated with two thermoplastic resin sheets and set into the investment mold as a core. Then the circumferential part of obturator was cured by the pour type resin.
    This technique was used to fabricate an obturator prosthesis in a 60-year-old post-maxillectomy patient. The weight of this obturator was well controlled and the definitive prosthesis weighed 22 g. At a one year follow-up, the obturator fared well without any water leakage or breakage.
    Conclusions: This technique allows the fabricator to control the thickness and weight of the obturator by the amount of relief provided by the hollow bulb. It also rectifies the disadvantages of the closed hollow obturator such as water leakage and complexity of fabrication.

    Background: Swallowing dysfunction (also known as dysphagia), which results in a deterioration of nutritional intake, slows rehabilitation and causes aspiration pneumonia, is very common following neurological impairments. Although videofluorographic (VF) examination is widely used for detecting aspiration, an objective and non-invasive method for assessing swallowing function has yet to be established because of a lack of adequate devices and protocols. In this paper, a bend sensor whose resistance is altered by bending was introduced to monitor swallowing-related laryngeal movement.
    Methods: Six healthy male volunteers were recruited in the present study. Specific time points on the signal waveform produced by the bend sensor were defined to describe laryngeal movement by differential analysis. Additionally, the physiological significance of the obtained waveform was confirmed by analyzing the sequential correlations between the signal waveform from the bend sensor and hyoid bone kinetics simultaneously recorded by VF.
    Results: Seven time points were successfully defined on the signal waveform to reference laryngeal movement. Each time point was well correlated with certain VF events, with evidence of no significant time lags, and there were positive correlations between waveform time points and matched VF events. Furthermore, obvious similarities were noticed between the duration of each phase on the signal waveform and the duration of the matched hyoid bone activity.
    Conclusions: The present monitoring system using a bend sensor might be useful for observing the temporal aspects of laryngeal movement during swallowing, and it was well coordinated with hyoid bone movement.

    Background:Flavor perception, the integration of taste and odor, is a critical factor in eating behavior. It remains unclear how such sensory signals influence the human brain systems that execute the eating behavior.Methods:We tested cerebral blood flow (CBF) in the frontal lobes bilaterally while subjects chewed three types of gum with different combinations of taste and odor: no taste/no odor gum (C-gum), sweet taste/no odor gum (T-gum), and sweet taste/lemon odor gum (TO-gum). Simultaneous recordings of transcranial Doppler ultrasound (TCD) and near infrared spectrometer (NIRS) were used to measure CBF during gum chewing in 25 healthy volunteers. Bilateral masseter muscle activity was also monitored.Results:We found that subjects could discriminate the type of gum without prior information. Subjects rated the TO-gum as the most flavorful gum and the C-gum as the least flavorful. Analysis of masseter muscle activity indicated that masticatory motor output during gum chewing was not affected by taste and odor. The TCD/NIRS measurements revealed significantly higher hemodynamic signals when subjects chewed the TO-gum compared to when they chewed the C-gum and T-gum.Conclusions:These data suggest that taste and odor can influence brain activation during chewing in sensory, cognitive, and motivational processes rather than in motor control. © 2013 Hasegawa et al.

    An in vitro evaluation system of food texture was developed using artificial tongue and a conventional uniaxial compression apparatus to mimic the tongue-palate compression. Deformation behavior of agar gels on artificial tongues from silicone rubber with three levels of elastic modulus was observed during compression by a nondeformable plate. The results were compared with the oral strategy for size reduction from sensory evaluation by human subjects. Agar gels fractured upon compression when the strain of the gels was larger than that of artificial tongue, whereas they did not when the strain of the gels was equivalent to or smaller than that of the artificial tongue. When apparent elastic modulus of artificial tongue was approximately 5.5x104Pa, fracture profile of the gels corresponded well to human tests. Results suggest that the oral strategy for size reduction might be determined by sensing the relative strain of the gels to the tongue during compression to a somewhat small strain. Practical Applications In an aged society, there is an increasing demand for properly texturized foods for safe consumption by those who have mastication or chewing difficulty. Food of soft texture is often preferred by these people because of easy tongue-palate compression and no need of the teeth mastication. An in vitro evaluation system of food texture developed in the present study provides a simple method for food manufactures in assessing textural acceptability of products without using human subjects. This evaluation system can lead to the innovation of food product design for textural diversity and thus improved quality of life for these disadvantaged populations.

    Background: For quantitative evaluation of masticatory ability of the elderly patients, there should be a simple and reliable method without special techniques and instruments. Objective: The purpose of this study was to examine the validity and reliability of a visual scoring method for assessing masticatory performance. Materials and Methods: A 10-stage scale for visually scoring was rated based on the range of the glucose concentration dissolved from comminuted jelly. Photographic images of comminuted jellies were produced as a standard material for each score. Fifty subjects were recruited as raters who graded the visual score for 50 photographic images of comminuted jellies on the screen of a lap-top three times in random order. Results: There were strong correlations (rs=0.9110.981, Spearman's rank coefficient) between the actual scores determined from the glucose concentration and the visual scores graded by subjects in all three measurements. The intraclass correlation coefficients (ICCs) of the inter-rater reliability and the ICCs of the intra-rater reliability of the visual scoring ranged from 0.946 to 0.947 and from 0.860 to 0.987 in three measurements, respectively. Conclusions: These results indicated that the visual scoring method was valid and reliable for evaluation of masticatory performance.

    Background: Although palatal augmentation prostheses (PAPs) can improve dysphagia, their application is compromised in the absence of maxillary abutment teeth. Experimental lingual plates (ELPs) used for raising the tongue may be employed as alternative to PAPs. Methods. Influence of different ELP designs, plateau (P-type) and drop-shaped (D-type), on the intra-oral pressure during swallowing were tested. Eleven healthy dentate volunteers, with a mean age of 35.5±10.5 years, participated in this study. Tongue pressure on the hard palate was measured using an ultra-thin sensor sheet with five measuring points, whilst performing dry, 5-ml and 15-ml water swallows, with and without the ELPs in situ. Additional pressure sensors were installed in the lingual aspects of the ELPs, and on the vestibular aspect of the lower molars for measuring sublingual and oral vestibule pressures, respectively. Each measurement was recorded thrice. A repeated measures ANOVA was employed to verify differences in duration, maximal magnitude and integrated value for the different experimental situations. Tukey's post hoc test was performed for comparison testing. Statistical significance was set at p&lt
    0.05. Results: The sequence of tongue-palate contact on the median line of the hard palate without ELPs was maintained, except for the 15 ml P-type swallow. Tongue pressure started earlier with the D-type but reached its peak nearly at the same time as without ELPs. The peak magnitude and cumulative tongue pressure against the hard palate decreased by wearing ELPs (p&lt
    0.05), but was inconsistent between the two types of ELPs and for the different swallowing volumes. Both, maximum and cumulative vestibular pressures were mostly similar or larger with P-type than that with D-type. Conclusion: D-type and P-type ELPs seem to have the inverse effect of PAPs on the palatal tongue pressure during swallowing. These first counterintuitive findings do not yet justify rejecting the basic rationale of using ELPs for the treatment of dysphagia
    hence a rather biologically designed piezographic lingual plate may be more appropriate. © 2013 Hori et al.

    Palatal augmentation prostheses are commonly used in the treatment for dysphagia. By lowering the palatal contours, the tongue contact is increased and thus the bolus propulsion facilitated. However, the unfavourable weight of such appliances may be avoided when using lingual plates. Hence, the aim of this study is to investigate the effect of two different types of lingual plates on the vertical dimension in rest position. Eleven healthy dentate subjects with an average age of 35.5 years (2660 years) volunteered in this pilot study. The vertical overbites were measured on plaster models. Two different designs of the experimental lingual plates were tested in this pilot study (P-type & D-type). The inter-occlusal freeway space was measured using the electromagnetic K7 jaw-tracking system (Myotronics, USA), while the subjects were seated in an upright position. They were asked to close from rest position into maximum intercuspation for about 2 s. Recordings were performed without the plates and subsequently with each of the two plate designs in situ. All recordings were performed three times and the second closing movement of each recording was used for the analysis. After averaging the repetitions without experimental lingual plates, with P-type and D-type plates, the differences were analysed using a KruskallWallis test. The results showed no significantly increased freeway space while using both types of lingual plates. Hence, it can be concluded that any altered tongue pressure during swallowing with lingual plates is not related to an increase in vertical dimension.

    The tongue assumes an important role in bolus formation and transportation to the oropharynx and in retaining pharyngeal pressure during mastication and swallowing. Although the state of tonguepalate contact during swallowing is thought to change with bolus type, the details of these changes have yet to be clarified under normal physiological conditions. The purpose of this study was to examine the effect of bolus type on tongue pressure production against the hard palate during swallowing. Tongue pressures during swallowing 10 mL of water and 10 g of pudding and during dry swallow were measured with a sensor sheet system with five measurement points to evaluate normal physiological swallowing in 10 healthy dentate individuals. There was a common pattern in the sequential order of tongue pressure generation among the three swallowing conditions: tongue pressure was generated significantly earlier at the anterior-median part, followed by the posterior parts. During swallowing pudding and dry swallow, the duration of tongue pressure tended to increase at all channels except for the posterior-median part. The maximal magnitude of tongue pressure was significantly higher when swallowing pudding than when swallowing water at all channels except for the posterior-median part. The integrated value of tongue pressure was significantly higher when swallowing pudding than when swallowing water at all channels except for the posterior-median part. From these results, it was considered the tongue changed the sequential order, the duration and the magnitude of tongue pressure production according to the swallowing conditions (liquid swallowing, semisolid swallowing, dry swallow).

    The purpose of this study was to compare the tongue pressure against the hard palate during the articulation of a monosyllable with that during swallowing. The participants were 20 healthy adults without swallowing or articulation disorder (10 men and 10 women, mean age +/- standard deviation: 22.5 +/- 0.9 years). Tongue pressure during articulation of [ki] (articulatory pressure) and during dry swallowing (swallowing pressure) was recorded by a 0.1-mm-thick sensor sheet with five measuring points attached to the hard palate. Biomechanical parameters such as maximal magnitude, duration, integrated value and slope gradient were compared between articulatory pressure and swallowing pressure at each measuring point. Although swallowing pressure was produced at each measuring point, articulatory pressure was found only in the posterior circumferential parts of the hard palate and was smaller in magnitude (14.916.7% of swallowing pressure) and integrated value, which meant the amount of work by tongue pressing (7.07.9%), shorter in duration (26.631.8%) and shallower in slope gradient, which meant the speed of tongue pressing (26.927.4%). Maximal magnitude was closely correlated with duration (R2 = 0.386) and slope gradient (R2 = 0.843) for articulatory pressure. These results first show the biomechanical differences between articulation and swallowing in terms of tongue contact with the hard palate. The findings suggest that tongue pressure measurement might be a useful investigation for patients with tongue motor disorder.

    The primary somatosensory cortex (Si) projects to the thalami's and brainstem somatosensory nuclei and modulates somatosensory information ascending to the Si itself. However, the projections from the Si to the brainstem second-order somatosensory neuron pools have not been fully studied. To address this in rats, we first revealed the somatotopic representation of orofacial areas in the S1 by recording cortical surface potentials evoked by stimulation of the lingual, mental, infraorbital, and frontal nerves. We then examined the morphology of descending projections from the electrophysiologically defined orofacial S1 areas to the pons and medulla after injections of an anterograde tracer, biotinylated dextranamine (BDA), into the orofacial S1 areas. BOA-labeled axon terminals were seen mostly in the trigeminal sensory nuclear complex (TSNC) and had a strong contralateral predominance. They also showed a somatotopic arrangement in dorsoventral and superficial-deep directions within almost all rostrocaudal TSNC levels, and in a rostrocaudal direction within the trigeminal caudal subnucleus. In the principal nucleus (Vp) or oral subnucleus (Vo) of TSNC, the BOA-labeled axon terminals showed a somatotopic arrangement closely matched to that of the electrophysiologically defined projection sites of orofacial primary afferents; these projection sites were marked by injections of a retrograde tracer, Fluorogold (FG), into the Vp or Vo. The FG injections labeled a large number of Si neurons, with a strong contralateral predominance, in a somatotopic manner, which corresponded to that presented in the electrophysiologically defined orofacial S1 areas. The present results suggest that the orofacial Si projections to somatotopically matched regions of trigeminal second-order somatosensory neuron pools may allow the orofacial Si to accurately modulate orofacial somatosensory transmission to higher brain centers including the orofacial S1 itself.

    Jaw clenching (clenching) is the result of an isometric contraction of jaw closing muscles. Because of the location of working muscles and afferent information during tooth contact, the effect of clenching on the cerebral and systemic circulation might differ from that of isometric limb exercise. This study aimed to investigate the characteristic changes in cerebral and systemic circulation during jaw clenching by comparing those during handgrip exercise. Subjects were 17 right-handed men. Bilateral middle cerebral arterial blood flow velocity (MCAV), electromyography (EMG) of contracting muscles, heart rate (HR) and blood pressure (BP) were measured during unilateral handgrip exercise and clenching tasks. Autonomic nerve activity was evaluated by analyzing fluctuations in HR and BP. MCAV was significantly increased during the task with significantly higher values on the non-working than working side irrespective of unilateral handgrip or unilateral jaw clenching. Changes in HR during jaw clenching were lower than those during handgrip exercise, and changes in vaso-motor sympathetic nerve activity during left jaw clenching were lower than those during left handgrip exercise. The present results indicate that, compared with handgrip exercise, unilateral jaw clenching promotes bilateral activation of MCAV with smaller effects on cardiac output and sympathetic nervous system activity.

    咀嚼能力はその評価すべき特性の多面性からこれまでに直接的及び間接的な評価法が多数検討されており、グミゼリーを被験食品とした研究では、成分の溶出計測や粉砕状況に応じたスコア化など種々の評価法を用いた報告がなされている。しかし、グミゼリー食塊粒子の詳細な粒度解析と成分溶出との関係についてはいまだ明らかになっていない。そこで本研究は、検査用グミゼリーを被験食品として含有β-カロチンの溶出量と、視覚判定による咀嚼能率スコアならびに画像解析による粒度解析との比較を行うことを目的とした。被験者は、成人健常有歯顎者17名(男性9名、女性8名、25〜53歳、平均30.8±6.9歳)とした。粒度計測はデジタル画像解析にて行い、β-カロチンは35℃の水に対する規定条件下での溶出量を評価した。咀嚼能率スコアは標準画像との比較により視覚的に決定した。咀嚼能率スコアと被験食塊中の最大粒子面積との間には有意の負の相関関係(p<0.001)が認められた。また1mm2〜50mm2の面積をもつ粒子の合計面積が咀嚼塊総面積に占める比率と溶出評価用センサ出力電圧との間に有意の負の相関関係(p<0.001)が認められた。以上の結果より、検査用グミゼリーからのβ-カロチン溶出量、目視による咀嚼能率スコアならびに粒度解析の結果は互いに相関関係が認められることが示された。(著者抄録)

    Objective. The aim of this study was to evaluate, with the use of magnetic resonance images, mandibular condyle and articular disc movement on occlusal splint application.
    Study design. Thirty-five subjects were classified into "Pain" and "No-pain" groups based on visual analog scale scoring of temporomandibular joint (TMJ) pain and were categorized as bilateral normal disc (ND), unilateral anterior disc displacement (ADD), or bilateral ADD position. t test and analysis of variance with multiple comparisons were used for statistical analyses.
    Results. Pain and No-pain groups showed significant anteroinferior and rotated movement of the condyle on splint application, but the disc did not significantly move in the Pain group. Of all groups, anteroposterior movement of the condyle and disc with the splint was significantly less in the unilateral ADD group.
    Conclusions. TMJ pain was associated with decreased movement of the articular disc. Disc and condyle movement was different in the unilateral ADD group in the presence of a splint compared with the ND and bilateral ADD groups.

    The purpose of this study was to investigate the influence of chin-down posture and bolus size on tongue pressure during swallowing. Eleven healthy volunteers (7 men, 4 women; age range = 26-59 years) participated in the experiments. Tongue pressure during dry and 5- and 15-ml water swallows in neutral and chin-down postures was measured using a sensor sheet system with five measuring points on the hard palate. Sequential order, maximal magnitude, duration, and integrated value of tongue pressure at each measuring point were compared between postures and bolus sizes. Onset of tongue pressure at posterior-circumferential parts occurred earlier in dry swallow than in 5- and 15-ml water swallows in each posture. Chin-down posture was most effective for increasing tongue pressure in the 5-ml water swallow compared with dry swallow and the 15-ml water swallow, but it had almost no influence on tongue pressure with the 15-ml water swallow. These results suggest that chin-down posture increases the tongue driving force for small boluses in healthy subjects, which can be interpreted to mean that oropharyngeal swallowing in a chin-down posture requires more effort.

    The aim of this study was to investigate the influence on cerebral hemodynamics of voluntary control of masticatory side and rhythm during gum chewing. Blood flow velocity in the middle cerebral artery was measured using transcranial Doppler ultrasonography to evaluate cerebral circulation in healthy volunteers. Heart rate and masseter muscle activity were recorded simultaneously. Volunteers performed three tasks: (1) free gum chewing, (2) gum chewing in which mastication was limited to the right side, and (3) gum chewing in which mastication was limited to the right side and rhythm was set at 1.0 Hz. Changes in cerebral circulation during pre-task, on-task, and post-task periods were analyzed using random effects model, and differences in cerebral circulation and muscle activity between tasks were analyzed using the Friedman test. In all tasks, on-task cerebral circulation was greater than pre-task. Muscle activity and masticatory rhythm varied between tasks, whereas the rate of increase in cerebral circulation did not differ significantly among tasks. These results suggest that cerebral circulation is activated during gum chewing, irrespective of voluntary control of masticatory side and rhythm.

    Mastication as a mild but life-long exercise has been examined as a possibility for maintaining brain function in the elderly. Little is known, however, about the cerebral circulatory response during masticatory movement. The aim of this study was to develop a monitoring system for circulation dynamics during masticatory movement and to apply this system to the study of cerebral autoregulation. Cerebral blood flow, heart rate, and arterial blood pressure were simultaneously recorded, and changes in these circulatory systems were quantitatively evaluated in 38 young healthy volunteers. Transfer function analysis was also performed on blood pressure and cerebral blood flow for investigation of cerebral autoregulation during gum chewing. Although increases in cerebral blood flow, mean blood pressure, and heart rate suggested the activation of cerebral and systemic circulation during gum chewing, increased cerebral circulation was independent of systemic circulation. Our results suggest that cerebral autoregulation is well maintained during jaw movements.

    Background and Purpose-Dysphagia is important for prognosis in patients with stroke because this condition can cause aspiration pneumonia or nutritional deficits. The present study investigated the relationship between tongue motor deficits and dysphagia in patients with acute stroke.
    Methods-Maximal tongue pressure on the hard palate when swallowing 5 mL of water was measured using a T-shaped sensor sheet with 5 measuring points in 33 dysphagic and 31 nondysphagic patients with acute stroke. Maximum tongue pressures at each measuring point were compared between dysphagic and nondysphagic groups and between paralyzed and nonparalyzed sides.
    Results-Tongue pressure at each measuring point was significantly smaller in dysphagic patients than in nondysphagic patients with the largest significant difference on the paralyzed side. The magnitude of tongue pressure to predict dysphagia was calculated as 4.6 kPa on the paralyzed side, offering 71.4% sensitivity and 72.3% specificity.
    Conclusions-Reduced tongue pressure on the paralyzed side may predict dysphagia in patients with acute stroke. (Stroke. 2010;41:2982-2984.)

    Although swallowing movement is known to change with aging, age-related differences in the tongue pressure for propelling a bolus from the oral cavity into the pharynx have yet to be investigated in a physiological condition. We hypothesized that tongue pressure during swallowing changed with aging and, using a 0.1-mm-thick sensor sheet with 5 measuring points, measured it while a 15-mL quantity of water was swallowed by young and elderly dentate individuals. Both groups showed a similar order of tongue pressure production at each point. However, the elderly group showed longer duration at each point, lower maximal magnitude in the anterio-median part of the hard palate, and higher magnitude in the circumferential parts of the hard palate than the young group. These results provide the first quantitative evidence of the age-related changes in tongue movement during natural swallowing, which could be attributed to muscle weakening and morphological changes in the oropharynx.

    The roles of supramedullary brain mechanisms involved in the control of jaw movements are not fully understood To address this issue, a series of retrograde (Fluorogold, FG) and anterograde (biotinylated dextran amine, BDA) tract-tracing studies were done in rats. At first, we identified projection patterns from defined sensorimotor cortical areas to subgroups of trigeminal premotoneurons that are located in defined brainstem areas Focal injections of FG into these brainstem areas revealed that the rostralmost part of lateral agranular cortex (rmost-Agl), the rostralmost part of medial agranular cortex (rmost-Agm), and the rostralmost part of primary somatosensory cortex (rmost-S1) preferentially project to brainstem areas containing jaw-closing premotoneurons, jaw-opening premotoneurons and a mixture of both types of premotoneurons, respectively The thalamic reciprocal connectivities to rmost-Agl, rmost-Agm, and rmost-S1 were then investigated following cortical injections of FG or BDA. We found many retrogradely FG-labeled neurons and large numbers of axons and terminals labeled anterogradely with BDA in the dorsal thalamus mainly on the side ipsilateral to the injection sites The rmost-Agl had strong connections with the ventral lateral nucleus (VL), ventromedial nucleus (VM), parafascicular nucleus, and posterior nucleus (Po), the rmost-Agm with the ventral anterior nucleus, VL, VM, central lateral nucleus, paracentral nucleus, central medial nucleus, mediodorsal nucleus and Po, and the rmost-S1 with the ventral posteromedial nucleus and Po The present results suggest that the descending multiple pathways from the cerebral cortex to jaw-closing and jaw-opening premotoneurons have unique functional roles in jaw movement motor control (C) 2010 Elsevier B V All rights reserved

    Dysphagia (difficulty in swallowing) is an important issue in the elderly because it causes aspiration pneumonia, which is the second largest cause of death in this group. It also causes decline in activities of daily living and quality of life. The oral phase of swallowing has been neglected, despite its importance in the evaluation of dysphagia, because adequate protocols and measuring devices are unavailable. However, recent advances in sensor technology have enabled straightforward, non-invasive measurement of the movement of important swallowing-related organs such as the lips and tongue, as well as the larynx. In this article, we report the present state and possibility of clinical application of such systems developed in Japan.

    Background: Although poststroke dysphagia is an important issue for determining prognosis, the pathophysiology of oral-phase dysphagia has yet to be clarified due to a lack of adequate devices and protocols. The present study investigated the relationships between swallowing pressure production by the tongue and dysphagia in stroke patients using a newly developed method of tongue pressure measurement with a sensor sheet system. Methods: Subjects were 64 stroke patients, including 30 patients with dysphagia. A T-shaped sensor sheet with 5 measuring points was attached to the hard palate to record tongue pressure while swallowing 5 ml of water. The average maximal magnitude and incidence of abnormalities such as asynchronous and/or polyphasic patterns in tongue pressure waves in 5 locations were compared between patients with and without dysphagia. Results: The average maximal tongue pressure was significantly smaller in patients with dysphagia than in those without dysphagia. Asynchronous and polyphasic patterns showed a sensitivity of 63 and 87%, and a specificity of 91 and 71%, respectively, for identifying patients with dysphagia. Conclusion: Tongue pressure production during swallowing appears closely related to poststroke dysphagia. Tongue pressure measurement appears useful for evaluating the pathophysiology of oral-phase dysphagia in stroke patients. Copyright (C) 2010 S. Karger AG, Basel

    In today's aging society, dentists are more likely to treat patients with dysphagia and are required to select an optimal treatment option based on a complete understanding of the swallowing function. Although the tongue plays an important role in mastication and swallowing as described in human oral feeding models developed in 1990s, physiological significances of tongue function has been poorly understood due to the difficulty in monitoring and analyzing it. This review summarizes recent approaches used to evaluate tongue function during swallowing quantitatively mainly focusing on modern sensing methods such as manofluorography, sensing probes, pressure sensors installed in the palatal plates and ultrasound imaging of tongue movement. Basic understanding on the kinematics and biomechanics of tongue movement during swallowing in normal subjects was provided by the series of studies. There have been few studies, however, on the pathological change of tongue function in dysphagic patients. Therefore further improvement in measurement devices and technologies and additional multidisciplinary studies are needed to establish therapeutic evidence regarding tongue movement, as well as the best prosthodontic approach for dysphagia rehabilitation. © 2009 Japanese Association for Dental Science.

    PURPOSE: The prosthodontic treatment of dysphagic patients may preclude favorable treatment outcomes due to uncoordinated or discordant oral and pharyngeal functions. Since optimal treatment requires a full understanding of the mechanism of oropharyngeal swallowing, this study seeks to describe the normal temporal pattern of tongue-, jaw-, and swallowing-related muscle coordination during voluntarily triggered swallows in healthy patients. MATERIALS AND METHODS: Tongue pressure against the hard palate at seven measuring points, swallowing sounds, and surface electromyography (EMG) activity of the masseter, anterior digastric, and infrahyoid muscles during voluntarily triggered swallowing were recorded in seven healthy male volunteers. The order of onset and offset of these parameters was analyzed by repeated-measures two-way analysis of variance. RESULTS: The onset of anterior digastric muscle activity occurred first and was significantly earlier than the onset of the masseter or infrahyoid muscles and tongue pressure. The onset of masseter muscle activity was also significantly earlier than that of the infrahyoid muscle and tongue pressure. Offset of masseter activity was almos

    Mastication has been proven to enhance the systemic circulation, with circulatory responses seeming to be largely regulated by autonomic nervous activity via a more complex regulatory system than those of other activities. However, few studies have examined the relationships between changes in autonomic nervous activity and the systemic circulation that are induced by masticatory movement. We investigated changes in the systemic circulation and autonomic nervous activity during gum chewing to clarify the influence of mastication. Electrocardiograms, arterial blood pressure, and masseter electromyograms were taken while chewing gum continuously as indicators of systemic circulation in 10 healthy subjects with normal dentition. Cardiac sympathetic activity and vagus nervous activity, as well as vasomotor sympathetic nervous activity, were evaluated by fluctuation analysis of heart rate and blood pressure. Repeated analysis of variance and multiple comparisons were performed to determine chronological changes in each indicator during gum chewing. Gum chewing increased the heart rate and the mean arterial pressure. Although cardiac sympathetic activity and vagus nervous activity showed significant changes, vasomotor sympathetic nervous activity did not. These results suggest that changes in the autonomic nervous activity of the heart are mainly involved in the enhancement of systemic circulation with gum chewing. This explains some characteristics of autonomic nervous regulation in masticatory movement.

    The structural design of removable partial dentures (RPDs) is critical for preventing distortion of the prosthesis, protecting abutment teeth and residual ridges as well as for high masticatory performance. The aim of this study was to clarify the feasibility and utility of a computer-aided designing (CAD) system with finite element analysis (FEA) for molar teeth arrangement in unilateral distal extension base RPDs. The shapes of artificial teeth and residual ridge were measured and converted into point group data. Solid models were created from surface-modelled point group data in a 3D surface CAD format. An occlusal rim was created on the residual ridge mucosa and the occlusal rim - residual ridge mucosa model with FEA function was created. Stress distribution on the residual ridge mucosa was compared by changing the loading point. The artificial teeth were then arranged in locations with the lowest amount of stress. After building an artificial teeth - saddle - residual ridge mucosa model, stress distribution in the residual ridge mucosa was re-evaluated by simulating occlusal force. On the occlusal rim - residual ridge mucosa model, stress was reduced when the loading point was located around the buccal shelf where functional cusps of artificial teeth were charted. It was confirmed that stress distribution in the residual ridge mucosa was equalized on the artificial teeth - saddle - residual ridge mucosa model. This system might be clinically useful tool for designing RPDs if FEA-guided designing of retainers and connectors can be added.

    To clarify features of direct projections from the primary somatosensory cortex (S1) to premotoneurons for the jaw-closing (JC) and jaw-opening (JO) components of the trigeminal motor nucleus, biotinylated dextranamine (BDA) and Fluorogold (FG) were used as the anterograde and retrograde tracers. The BDA and FG injections were made in the S1 and the JC or JO component, respectively, in rats. The distribution of FG-labeled JC and JO premotoneurons receiving contact(s) from BDA-labeled axon terminals of S1 neurons was quantitatively examined; the contacts were identified microscopically by using a X100 oil immersion objective. The largest and second largest numbers of JC and JO premotoneurons with contact(s) were found in the lateral reticular formation at the levels of the caudal pons and the medulla oblongata (cpmLRt) and trigeminal oral nucleus (Vo) bilaterally, and they comprised about 80% of the total premotoneurons with contact(s). The percentage of premotoneurons with contact(s) was higher in the Vo than in the cpmLRt for both JC and JO premotoneurons. Most of the JC or JO premotoneurons found in the nucleus of the solitary tract, inter- and supratrigeminal regions, mesencephalic trigeminal nucleus, parabrachial nucleus and reticular formation medial to the JO component of the trigeminal motor nucleus hardly received contact(s) from S1 neurons. This suggests that the contribution of S1 to the control of jaw movements is mediated via JC and JO premotoneurons located primarily in the cpmLRt and Vo areas of the brainstem.

    Purpose: The aim of this study was to develop a sensor sheet for measuring tongue pressure during swallowing and to clarify its usefulness by comparing it with a conventional pressure sensor installed in the palatal plate.
    Methods: A tactile sensor system was used for the construction of the measuring system. Based on our preceding study, a T-shaped sensor sheet with 0.1 mm thickness, five measuring points (three points on the median line, two points on the posterior-lateral part) and three sizes based on the morphological analysis of 60 maxillary casts was designed for application on the hard palate. To elucidate the sensing characteristics of the sensor sheet, the output level of the sensor sheet was compared with that of a conventional pressure sensor under the same load. The maximal magnitude of tongue pressure (MP) during the swallowing of 15 ml water was recorded by a sensor sheet attached to the palatal mucosa and was compared with that recorded by pressure sensors installed in the palatal plate.
    Results: The output level of the sensor sheet was smaller than that of the pressure sensor. There was a high correlation between the output levels of the two sensors (R = 0.952, P &lt; 0.001). Although MP at each sensing point of the sensor sheet was also smaller than that recorded by the pressure sensors, MP collected by the regression equation obtained in our experiment was quite similar to that for the pressure sensors.
    Conclusions: This system could be useful for evaluating tongue activity during oropharyngeal swallowing. (C) 2009 Japan Prosthodontic Society. Published by Elsevier Ireland. All rights reserved.

    Mandibular condyle plays an important role in the growth and reconstruction of the temporomandibular joint (TMJ). We aimed to obtain orthotropic elastic parameters of the condyle using a continuous-wave ultrasonic technique and to observe the effects of condylar elastic parameters on stress distribution of the TMJ using finite element analysis (FEA). Using the ultrasonic technique, all nine elastic parameters were obtained, which showed that the mandibular condyle was orthotropic. With the condyle defined as orthotropic, the occlusal stress was transferred fluently and uniformly from the mandible to the TMJ. The stress distribution in the isotropic model showed stepped variation among different anatomical structures with higher stress values in the cartilage and condyle than in the orthotropic model. We conclude that anisotropy has subtle yet significant effects on stress distribution of the TMJ and could improve the reality of simulations.

    Vertical alveolar augmentation by distraction osteogenesis has become a standard pretreatment of dental implants due to the main benefit of lack of donor site complications, and many reports have shown its benefit with various types of alveolar distractors. However, autogenous bone transplantation and/or guided bone regeneration techniques are still the standard treatment for correcting a narrow alveolar ridge because of few commercially available distractors for alveolar widening. In this article, we treated a case by a mesh-plate type of alveolar widening distractor for a narrow posterior mandibular alveolar ridge after extirpation of a large jaw cyst.

    Tongue plays an important role by making contact with palate in swallowing. This study was aimed for investigating the utility of originally developed measuring system of tongue pressure in the rehabilitation of dysphagic patients with prosthesis. Subject was a 68 years old male post-surgical laryngeal cancer patient who underwent percutaneus endoscopic gastrostomy because of dysphagia. Tongue pressure during dry swallow was recorded by using our original sensor sheet system (Nitta, Japan) with five measuring points (Chs.1-5) attached on the palatal surface of maxillary denture (RPD). Tongue impression was taken by his maxillary denture and the palatal contour was changed into palatal augmentation prosthesis (PAP), then tongue pressure with PAP was recorded and compared with that with RPD. Magnitude of tongue pressure on median line (CHs.1-3) of palatal surface of RPD was nearly 0 and that on the circumferential part (Chs.4 and 5) had laterality. In PAP, however, magnitude of tongue pressure on the median line increased and showed normal pattern (Ch.1>Ch.2>Ch.3) and that on the circumferential part showed no laterality. Improvement of the tongue pressure production described by our system might contribute to the bolus transport in oral phase of swallowing.

    To investigate the role of integrin and G protein pathways in the mechanotransduction process within MCCs and explore the possible crosstalk between the two traditional signal pathways, in vitro-cultured rabbit MCCs were treated with pressure. The mRNA level of alpha 5 beta 1 integrin was determined by in situ hybridization and the distributions of vinculin, G alpha q/11 protein, F-actin and intracellular calcium were studied with a laser scanning confocal microscope. Increased integrin alpha 5 beta 1 expression, enhanced stress fiber assembly, elevated G protein and vinculin level and up-regulated IP3 channel sensitivity were found in the mechanotransduction Process of MCCs under pressure. Furthermore, the vinculin and the G alpha q/11 were observed co-localized with each other, and the F-actin reassembly and stress fibers formation could be inhibited by intracellular calcium, channel blocking, which gave direct evidence that the traditional integrin-mediated or G protein-mediated signaling pathways coordinately regulate the function of MCCs under mechanical stimulation.

    In elderly persons, it is thought that maintenance of masticatory function may have a beneficial effect on maintenance of cerebral function. However, few studies on cerebral circulation during mastication exist. This study aimed to verify a possible increase in cerebral circulation and the presence of cerebral hemispheric dominance during gum chewing. Twelve healthy, young right-handed subjects with normal dentition were enrolled. Bilateral middle cerebral arterial blood flow velocities (MCAV), heart rate, and arterial carbon dioxide levels were measured during a handgrip exercise and gum chewing. During gum chewing, electromyography of the bilateral masseter muscle was recorded.MCAV and heart rate significantly increased during exercise compared to values at rest.During gum chewing, there were no differences in the rate of increase in MCAV between the working and non-working sides, but during the handgrip exercise, the rate of increase in MCAV was significantly greater for the non-working side than for the working side.During gum chewing,muscle activity on the working side was significantly greater than that on the non-working side. These results suggest that during gum chewing, cerebral circulation increases bilaterally and does not show contralateral dominance, as it does during the handgrip exercise.

    Objective: To investigate the influence of maximal bite force, maximal tongue pressure, number of mastications and swallowing on the oro-pharyngeal residue in the elderly.
    Background: Oro-pharyngeal residue in the elderly is an indication of clysphagia. Pharyngeal residue is especially critical as it may cause aspiration pneumonia, which is one of the major causes of death in elderly.
    Materials and methods: Videofluorographic recordings were performed on 14 elderly volunteers (six males, eight females, age range 65-93 years) without any history or symptoms of dysphagia. The subjects were instructed to consume 9 g of barium containing bread in two manners; free mastication and swallow (FMS: masticate and swallow freely), and limited mastication and swallow (LMS: swallow once after 30 chewing actions). The amount of oral and pharyngeal residue was evaluated using a 4-point rating scale. Maximal occlusal force was measured by a pressure sensitive sheet, and maximal tongue pressure using a handy probe. Multiple regression analysis was performed to examine the influence of these items on the amount of oral and pharyngeal residue in FMS and LMS.
    Results: In FMS, age was found to be a factor which increased oral residue (p = 0.053), and the number of swallowing (p = 0.017) and the state of the prosthesis (p = 0.030) reduced the pharyngeal residue. In LMS, tongue pressure was a factor which reduced oral residue (p = 0.015) and increased pharyngeal residue (p = 0.008).
    Conclusion: It is suggested that in the elderly tongue pressure contributed to propulsion of the food bolus from oral cavity into the pharynx, and multiple swallowing contributed to the reduction in the amount of pharyngeal residue.

    This study was performed to complement the results of prior intracellular recording and labeling studies by investigating the general distribution pattern of trigeminal premotoneurons in the cat brainstem using the retrograde tracing methods. The results of the present study reconfirmed the presence of premotoneurons in the trigeminal principal and oral nuclei following horseradish peroxidase injections into the jaw-opening (JO) or jaw closing (JC) nucleus. Furthermore, we found that labeled cells from the JO nucleus and JC nucleus located in the reticular regions surrounding the trigeminal motor nucleus (Vmo; Vmo shell region) were arranged in a topographic fashion, while those in the parabrachial nucleus, supratrigeminal nucleus, lateral reticular formation caudal to the shell region and raphe nuclei were intermingled with each other. The labeling in the individual nuclei was bilateral with an ipsilateral predominance to each injection site, with the exception of the mesencephalic trigeminal nucleus, where the labeling was ipsilateral to the injection site in the JC nucleus. These results, combined with the data of the previous intracellular tracing studies, indicate that based on the presence of somatotopic organization, premotoneurons can be largely divided into two groups; those projecting to either the JO or the JC nucleus and those projecting to the two nuclei, and we offer the suggestion that roles of premotoneurons for jaw movements differ among the individual nuclei.

    Purpose: Oral cancer develops frequently in older populations. In Japan, the incidence of oral and pharyngeal cancer is 9,201 per year, with such tumors accounting for 1.74% of all cancers. Although obturator prostheses play an important role in the rehabilitation of postmaxillectomy patients, clinicians sometimes experience difficulty in placing obturator prostheses in edentulous maxillae, and criteria for the objective evaluation of treatment outcome have yet to be established. The present study aimed to investigate postsurgical factors influencing the masticatory performance of postmaxillectomy patients with edentulous maxillae fitted with obturator prostheses. Materials and Methods: The extent of the hard palate defect, status of the mandibular dentition, mouth-opening distance, and maximum occlusal force were investigated, and masticatory performance was measured using a testing gummy jelly in 27 postmaxillectomy patients with edentulous maxillae fitted with obturator prostheses. The influence of these items was evaluated quantitatively, and theoretical masticatory performance for each subject was calculated using multiple-regression analysis (quantification method type 1). Results: Although average masticatory performance was almost equivalent to that of healthy, independent older patients with occlusal support classified as Eichner C, considerable individual variation was noted among subjects. The order of strength of influence on masticatory performance was identified by category weight: extent of hard palate defect &gt; status of posterior mandibular teeth &gt; maximum occlusal force &gt; mouth-opening distance. A relatively high correlation (R-2 = 0.78, P &lt;.01, Pearson correlation coefficient) was evident between theoretical and actual values. Conclusion: Masticatory performance could be predicted by evaluating postsurgical factors in patients with edentulous maxillae fitted with obturator prostheses.

    Temporal changes in cerebral blood flow induced by jaw movement have yet to be investigated. To assess the influence of pattern and intensity of muscle contraction during jaw movement on task-induced change in cerebral blood flow, we performed bilateral transcranial Doppler ultrasound examination during clenching, gum chewing, and tooth tapping in healthy volunteers. A random-effects model analysis revealed a significant increase in middle cerebral artery blood flow velocity during clenching (high muscle activity) and gum chewing (moderate muscle activity), compared with the preceding rest period; however, such an increase was not detected during tooth tapping (low muscle activity). Cerebral blood flow was greater on the working side during the intensive isometric contraction of the masseter muscle in clenching. These results suggest that task-induced change in cerebral blood flow during jaw movement is influenced by the change in peripheral circulation evoked by muscle contraction.

    The tongue plays an important role in mastication and swallowing by its contact with the hard palate. Using an experimental palatal plate with 7 pressure sensors, and recording jaw movement using mandibular kinesiography, we assessed, in healthy subjects, the coordination of tongue and jaw movements during the entire masticatory sequence of solids, by measuring tongue pressure against the hard palate. Tongue pressure appeared during the occlusal phase, reached a peak near the start of opening, and disappeared during opening. Specific patterns in order, duration, and magnitude of tongue pressure were seen at the 7 pressure sensors in each chewing stroke. Magnitude and duration were significantly larger in the late stage of chewing (8 strokes before initial swallowing) than in the early stage (until 8 strokes after starting mastication). The normal pattern of tongue contact against the hard palate, control of tongue activity, and coordination with jaw movement during mastication is described.

    In a previous report, we investigated the influence of the shooting angle of polishing particle on the Surface roughness of a cobalt-chromium (Co-Cr) alloy using a centrifugal shooting type polishing machine. In the present work, we examined the effects of the texture of polishing particle and polishing time on the surface roughness of Co-Cr alloy cast specimens. Nine different textures of polishing particle were investigated with respect to core material and particle abrasiveness: three different elastic body cores (core A, hard chloroprene rubber; core B, soft chloroprene rubber; core C, natural rubber) and three different green carborundum powders as abrasives (# 800, # 3000, and # 6000). Polishing was performed under a fixed shooting angle of 30 degrees for six different polishing times (1, 2, 3, 5, 7, and 10 minutes). Surface roughness (Ra, Sm) and cutting depth on the polished surface were measured after each polishing stage. Surface roughness was significantly improved within three minutes, particularly using a polishing particle with rough carborunclum powder (# 800 or # 3000) and a heavy Core (core A or core B). Cutting depth increased in proportion to polishing time and roughness of carborundum powder, and was least with core C. These results suggested that. a polishing particle composed of core B and # 3000 carborundum paste was Superior for the intermediate polishing of a Co-Cr alloy, and that polishing time Should he limited to within three minutes.

    The centrifugal shooting type polishing machine is a recently developed apparatus that seeks to improve the efficiency and environment of polishing removable prostheses. In an attempt to optimize the effectiveness of this apparatus, this study examined the influence of the shooting angle of polishing particle on the surface roughness of cobalt-chromium alloy casting specimens. Polishing was performed for three minutes under five shooting angle conditions: 90 degrees, 60 degrees, 45 degrees, 30 degrees, and 15 degrees. Surface roughness (Ra, Sm) was measured after each polishing stage. There were significant differences (p &lt; 0.01) in Ra between shooting angle of 90 degrees (0.95 mu m) and shooting angles of 45 degrees (0.62 mu m) or less, and in Sm between 90 degrees (207 mu m), 60 degrees (350 mu m), and shooting angles of 45 degrees (868 mu m) or less. These findings indicated that excellent surface texture was produced when shooting angle was 45 degrees or less.

    Contact of the tongue against the hard palate plays an important role in swallowing. This study aimed to clarify the pattern of contact between the tongue and hard palate by analyzing tongue pressure produced in swallowing 15 ml of water by healthy subjects wearing an experimental palatal plate with seven pressure sensors. Tongue pressure was generated initially by close contact with the anteriomedian part of the hard palate, then with the circumferential part, and finally softly with the posteriomedian part. Tongue pressure reached a peak quickly, then decreased gradually before disappearing almost simultaneously at each measured part of the hard palate. Magnitude and duration were significantly larger in the anteriomedian part compared to the other six parts measured, and was significantly smaller in the posteriomedian part. No laterality was found in tongue pressure produced at the circumferential parts of the hard palate. Our findings indicate that the order of tongue contact against each part of the hard palate as well as duration and magnitude of tongue pressure are coordinated precisely during swallowing. These findings could aid assessment of the tongue movement of dysphagic patients during rehabilitation.

    Recently, a newly developed magnetic attachment with stress breaker was used in retentive components in overdentures. Excessive lateral stress has a more harmful effect on natural teeth than axial stress, and the magnetic attachment with stress breaker is expected to reduce lateral forces on abutment teeth and protect it teeth from excessive stress. However, the properties of this retainer have not yet been determined experimentally. This study compares the lateral forces on abutment teeth for three retainers under loading on the denture base in a model study. A mandibular simulation model is constructed to measure lateral stress. Three types of retentive devices are attached to the canine root. These devices include the conventional root coping, the conventional magnetic attachment and the new magnetic attachment with stress breaker. For each retentive device, load is generated on the occlusal table of the model overdenture, and the lateral stress on the canine root and the displacement of the overdenture measured. The magnetic attachment with stress breaker does not displace the denture and exhibits lower lateral stress in the canine root than conventional root coping and magnetic attachments.

    The purpose of this study was to confirm the dimensional accuracy of a newly developed injection pressing method for resin polymerization by making use of the internal electric resistance of resin to determine the optimal timing for resin injection. A new injection pressing polymerization pot with a built-in system to measure the internal electric resistance of resin was used for resin polymerization. Fluid-type resin was injected into the mold of a maxillary complete denture base under nine different conditions: three different timings for resin injection according to the electric resistance of resin dough (early stage: 11 MOmega; intermediate stage: 16 MOmega; final stage: 21 MOmega) and three different motor powers for resin injection (2000 N, 4000 N, and 6000 N). In the best polymerization condition (injected during the early stage of resin dough under a motor power of 6000 N), the adaptation of the denture base showed a statistically significant improvement compared with the conventional pouring method.

    The purpose of this study was to determine the influence of dental status on oral function and satisfaction among a group of independently living elderly persons in an urban area of Japan. The study sample consisted of participants of the Senior Citizens' College from 1995 to 1999. Their dental status and oral satisfaction were measured by a questionnaire. The number of usable questionnaires was 3967, or 80.8% of the total sample. The mean age of the subjects was 66.5+/-4.3 years, and 52.2% were male. Twenty-nine percent of them had a natural dentition, and 7.0% were edentulous in both jaws. The prevalence of edentulism in the study sample was significantly lower (p &lt
    0.01) than that for the national survey. Overall, 66.4% of the subjects were satisfied with their ability to chew, 56.2% with the appearance of their teeth, 63.1% with their ability to speak clearly, and 76.5% with their ability to taste food. For complete-denture wearers, the greatest dissatisfaction was with speech (28.5%)
    however, for the RPD wearers, it was with chewing ability (21.7%). Sixty-one percent of complete-denture wearers reported that they were satisfied with their chewing ability, but only 11% of them could eat all three of the evaluated foods without difficulty. The multiple stepwise logistic regression analyses showed that both dental status and self-assessed general health had a significant association with dissatisfaction with all four oral functions and self-assessed impairment of chewing ability. There were significant associations between the elderly subjects' dental status and oral function.

    The purpose of this study was to examine the prevalence of perceived dry mouth among a group of independently-living elderly persons in Japan, and to determine its association with general disease, medication, and dental status, as well as its effect on oral function. The study population consisted of participants of the Senior Citizens' College. The subjective sensations of oral dryness on waking and while eating a meal were measured by a questionnaire. The number of usable questionnaires was 1003 or 77.9%. The mean age of the subjects was 66.3 ± 4.2 years, and 53.0% were male. More than one-third (37.8%) of the subjects reported oral dryness on waking. Only 9.1% of them noticed a subjective feeling of dry mouth during eating. Persons who had at least one of these symptoms made up 41.0%. A multiple stepwise logistic regression analysis indicated the following results: Perception of dry mouth on waking was more frequent among males (p &lt
    0.001), persons who had a low BMI (p &lt
    0.05), and those taking two or more prescribed drugs (p &lt
    0.01). Sensation of dry mouth when eating was more frequent among subjects with a low BMI (p &lt
    0.001) and those who wore a denture in the maxillary arch (p &lt
    0.05). Perception of dry mouth when eating was associated with self-assessed chewing ability (p &lt
    0.01) and dissatisfaction with speaking clearly (p &lt
    0.05), as well as dental status. However, dissatisfaction with tasting a meal had a significant relationship with the reports of mouth dryness on waking (p &lt
    0.01). Our findings suggest that a substantially higher percentage of persons have the perception of dry mouth on waking than when eating, which was associated with medications, being male, and having a low BMI. This perception may influence oral function, especially the reported dissatisfaction with tasting foods.

    The purpose of this study was to analyze the relationship between quality of removable dentures and nutrient intake in the elderly. Subjects were 323 community dwelling, independently living elderlypeople (174 males and 149 females) aged 60-79, of which the mean age was 66.3±4.3 years.<BR>Diet was assessed by licensed dietitians via interview for 3 days. The data on food consumption were converted to the nutrient content such as energy (kcal), protein, and calcium. The ratio of actual nutrient intake per recommended nutrient intake was evaluated as a measure of dietary adequacy. Student's t-test, Mann-Whitney U-test, and one-way ANOVA were used for statistical analysis.<BR>The nutrient intake, except iron, was sufficient in both dentate and denture wearer groups. Among removable denture wearers, nutrient intake tended to be lower in the low occlusal force group than in the high group. There were significant differences in protein and iron intake in males between the two groups (p<0.05), and the nutrient intake also tended to be lower in the group dissatisfied with removable denture than in the group satisfied therewith.<BR>The results indicated that both occlusal force and satisfaction with removable dentures were associated with nutrient intake of elderly people.

    It has been proved in previous studies that the surface treatment of cobalt-chromium alloy with gold dust was effective not only to increase the bonding strength between metal and porcelain, but also to cover metal color and prevent the border coloring.<BR>In this study, two kinds of gold alloys for porcelain fusing indifferent compositions (Select 50 and Select 77 H, Ohura Precious Metal Co.) were selected to examine the effect of metal surface treatment with gold dust on the bonding strength. The size of gold dust (Super-Binder OG, Ohura Precious Metal Co.) used in this study was 1.0 μm in a uniform diameter.<BR>The results showed that both alloys exhibited stronger bonding strength after treated with gold dust, particularly in the case of Select 50. Most of the gold dust remained on the fractured surface of Select 50 specimens after the shear test, observed by scanning electron microscope. It was also found that gold dust existed on both metal and porcelain surfaces in the case of Select 77 H.<BR>The above results suggested that the treatment of a metal surface with gold dust could reinforce the bonding strength between gold alloy and porcelain. Furthermore, the bonding strength would increase greatly if the gold dust was bonded firmly to the metal surface.

    The purpose of this study is to investigate the influence of setting expansion and thermal expansion of the phosphate-bonded investment on the fitness of cast clasps fabricated by a superelastic Ni-Ti alloy. Investment models were made from the columnar stainless-steel model supposed the abutment tooth the various dilusion colloidal silica solutions. Cast clasps were fabricated using by using a superelastic Ni-Ti alloy, then dimensional changes at the tip and mid-point of clasp arm between before and after fitness of cast clasps to the stainless-steel model were measured by the using of a profile projector. In addition, setting expansion and thermal expansion of investments were measured. Results were as follows : (1) Setting expansion increased with the increse of the concentration of colloidal silca solution, however thermal expansion kept constant. (2) Cast clasps fabrcated by using the investment model with 1.6% of setting expansion and 1.0% of thermal expansion showed the best fitness.

    The purpose of this study is to develop a rational fabricating system for determining retentive force of cast clasps. The radius of curvature of a circumferential clasp arm is considered to be one of the important factors affecting dynamical properties of cast clasps. In this study, a device for determining the radius of curvature and a computer system for Akers claspsand I-bar clasps were developed. It was suggested to be very significant in partial denture designing, that the retentive force and the bending rigidity required according to various conditions around abutment teeth can beeasily obtained by using a personal computer, and that the proper part of a commercially available clasp pattern required to fabricate cast clasps providing rational retentive forces can be determined in this system.

    Ni:56.5wt%,Ti:43.5wt%を含むNi-Ti合金は良好な超弾性効果を有している。この超弾性効果は,比例限を越える大きな変形をあたえても,荷重を取り除けば永久変形を残さずに原形に復するというものであり,キャストクラスプの材質として非常に有望である。本研究は,既製ワックスパターンを用いて各種寸法の鋳造体試料を作製し,片持ち曲げ試験を行ってその曲げ特性について分析し,同合金の臨床的有用性について検討したものである。

    下顎欠損患者にインプラント顎義歯を製作後、機能評価を行った論文を抽出し、その効果と影響因子について検討した。PubMedと医中誌を検索し、28編が今回の検討対象論文として抽出された。咬合力、咀嚼能率、食物摂取調査の咀嚼スコアを用いた評価において、インプラント顎義歯装着後にスコアが有意に向上したとする報告、同一患者において従来の顎義歯よりもインプラント顎義歯のほうが欠損側における咀嚼能率が高いといった報告、摂取可能な食品が増加したといった報告などがあげられていた。隣接軟組織の切除症例の報告から、インプラントにより補綴装置の維持・安定性が確保されても、本来軟組織が担っている機能が代償されるわけではないと考えられた。腓骨や腸骨により下顎骨再建を行った症例に関して、従来の顎義歯では安定が得られにくい症例においては有効な治療法となりうると考えられた。

    上顎欠損の治療法としての顎義歯と外科的再建について文献的比較検討を行った。PubMedと医中誌を検索し、37編(和文10編、英文27編)が今回の検討対象論文として抽出された。上顎亜全摘術(眼窩底保存)以下の上顎部分切除術に相当する硬口蓋・歯槽部片側欠損以下で、残存歯があれば顎義歯が有効であることが示された。また、腫瘍制御に不安ないし困難な症例では顎義歯が適用され、経過良好であれば必要に応じ二次再建について検討するとする治療選択も報告されていた。生命予後は大欠損をきたすような進展例では不良であり、顎義歯を選択するか再建手術を選択するかは個々の患者のQOLを優先して、適切な治療法を選択すべきと考えられた。修復方法として顎義歯か外科的再建のいずれを選択するが、後者を選択するとしても適切な再建手術手技の検討に欠損分類は不可欠であると考えられた。

    近年、高齢者のフレイル予防と健康長寿における咀嚼の重要性が注目されている。咀嚼は運動としては軽微であるが、豊富な感覚情報や情動変化を伴うため、脳循環や体循環を賦活化する効果を有している。また、客観的な咀嚼能力検査によって、咀嚼能力の低下がメタボリックシンドローム罹患のリスクとなることが示唆された。さらに、肥満予防を目的とした咀嚼行動変容を促すための、ウエアラブルデバイスの開発が行われている。このように、運動、能力、行動の様々な面からアプローチすることによって、咀嚼を利用した高齢者のヘルスプロモーションの可能性が広がるものと期待される。(著者抄録)

    <文献概要>簡易な機器で舌挙上に負荷を加えることを目的とし,ばねばかりを用いた簡易な舌-口蓋接触トレーニングを考案した.本研究では,ばねばかりにより調節した牽引負荷が舌圧に与える影響を検討した.対象は最大押し付け舌圧が各年代の平均値未満であった嚥下障害を呈する患者20名とした.方法は,はかりに固定したガーゼを舌-口蓋接触の力のみで10秒間保持するように指示し,評価者がはかりを牽引した.負荷量は50g,100g,200g,300gの4条件を設定した.牽引時の舌圧最大値,舌圧積分値を舌圧センサシートで記録,解析し,負荷量の増加に伴う舌圧の増加傾向の有無の検定,各条件間での比較を行った.口蓋の正中前方部,左右後方周縁部では,牽引力の増加に伴い,舌圧最大値,舌圧積分値は有意な増加傾向を認めた.また正中前方部の舌圧最大値,舌圧積分値は各条件間で有意差を認め,牽引力の増加に伴って舌圧が増加した.ばねばかりを用いた簡易な舌-口蓋接触トレーニングは舌前方部へ負荷を加えるトレーニングとして利用できる可能性が示唆された.

    摂食嚥下リハビリテーションにおける歯科医師に期待される役割の一つに、補綴的なアプローチが挙げられる。このアプローチの中では、有床義歯の製作・調整だけではなく舌接触補助床(PAP)をはじめとするさまざまな装置が用いられる。舌接触補助床とは、舌機能の低下した患者に対して舌機能の代償を図るために装着される、上顎の床タイプの補綴装置のことである。こういった装置の製作・調整においては、時として専門的な補綴に関する知識や経験・技術を必要とする。また、その適応を適切に判断することも重要となる。補綴装置はうまく使用していただかないと効果を発揮しないだけでなく、不適合な装置はかえって機能を阻害する可能性がある。一方、摂食嚥下リハビリテーションはチーム医療が基本であり、多職種によるさまざまなアプローチを組み合わせて行われることが多い。PAPを用いた補綴的なアプローチだけではなく、各職種と連携して筋可動域訓練や筋負荷訓練といった間接訓練や、嚥下姿勢や食事の調整といった直接訓練なども検討してリハビリテーションプログラムに組み入れられる必要がある。保険医療におけるPAPの適用が摂食機能療法との併用を前提としているのも、こうした機能訓練や栄養管理、リスク管理がなければPAPの効果を十分に上げられないからである。本稿では、PAPを用いた摂食嚥下リハビリテーションの実際について、装置の製作方法やその際の注意点について解説するとともに、あわせて行われるリハビリテーションなどについても言及し、より効果的な嚥下機能回復を図るための方策を考えたい。また、その効果や新たな取り組みについて、検討する。(著者抄録)

    極薄型の舌圧センサシートを口腔内に貼付することにより、自然な嚥下時の舌圧を多点で測定することができる。舌圧の持続時間、最大値、順序性、左右バランスなどのパラメータの変化は、脳卒中、神経筋疾患、口腔中咽頭がんなど各疾患特有の舌のmotor controlの異常と関連しており、不顕性の嚥下機能低下を捉えるうえで有用である。また、嚥下時舌圧データは、嚥下手技の舌に対する効果検証や、患者個々の舌機能に応じた食品性状の設定に応用することによって、摂食嚥下リハビリテーションにおけるさまざまなアプローチの合理化や効率化に貢献する可能性をもつと考えられる。(著者抄録)
