Objective: One of the main causes of subjective oral dryness in the elderly is the side effects of medication. In addition, the elderly's tolerance to stress is low, and stress may induce many symptoms including mouth dryness. Thus, it is necessary to examine their psychological well-being. However, few reports have considered the relationship between subjective oral dryness and psychological well-being. Furthermore, few reports have examined subjective oral dryness, medication use, and psychological well-being simultaneously. The purpose of this study was to investigate the rate of subjective oral dryness and effects of psychological well-being and medication in the elderly. Methods: A questionnaire survey and interview concerning subjective oral dryness, medication use, and psychological symptoms were conducted involving 398 elderly aged 77-78 years old in Japan. The rates of the side effect of subjective oral dryness caused by medication and drug efficacy were investigated using the book 'Drugs in Japan'. The Japanese version of a general health questionnaire (GHQ 30), a self-entry type questionnaire, was used to evaluate psychological well-being. The elderly with scores greater

A brief-type self-administered diet history questionnaire (BDHQ) is a validated method of dietary assessment. This study investigated the relationship between the speed of eating, which is considered an eating behavior, and the estimated nutrient intake using the BDHQ in community-dwelling Japanese aged 80 years old. Three hundred and fifty-four participants (174 males and 180 females) aged 80 years old who participated in both dental examinations and BDHQ assessment conducted in 2008 were included in the analysis. The speed of eating was self-reported by giving a response chosen from five qualitative categories: 'very fast', 'relatively fast', 'medium', 'relatively slowly', and 'very slowly'. The five categories were classified into two categories for statistical analysis, that is, participants who answered 'very fast' and 'relatively fast' were defined as 'eating fast', while those who answered 'medium', 'relatively slowly', and 'very slowly' were defined as 'eating slowly'. The nutrient intake was calculated from the BDHQ using the ad-hoc program developed for nutrient calculation based on BDHQ responses. The estimated nutrient intake was compared between the two groups defined as eating 'fast' or 'slowly'. Furthermore, multivariable linear regression analysis was conducted using the speed of eating, gender, BMI, number of teeth, and masticatory function as independent variables to assess the influence on the estimated nutrient intake. The participants defined as eating 'fast' consumed significantly more zinc, copper, cryptoxanthin, and vitamin C than participants defined as eating 'slowly' (p=0.012, p=0.022, p=0.007, and p=0.049, respectively; Student's t-test). Moreover, the zinc, copper, cryptoxanthin, and vitamin C intakes of participants defined as eating 'fast' remained significantly higher than those of participants defined as eating 'slowly' after simultaneously adjusting for possible confounders (p=0.027, p=0.039, p=0.004, and p=0.043, respectively). The findings of this study suggest that Japanese people aged 80 years old who define themselves as eating fast consume higher levels of nutrients that are included in meat, fish, shellfish, vegetables, and fruits.

Dental examinations are often conducted in cities, towns, and villages as part of an oral health program for adults. However, in many places, a low percentage of subjects participate in these programs. This study evaluated the effects of a prevention program on periodontal disease focusing on personal education for adults, assessing whether or not the percentage of subjects who use interdental brushes or dental floss daily increase. Seventy-three mothers were surveyed in S city in Niigata Prefecture. Clinical examinations were performed for mothers who visited their local health centers while taking their children for their 1- or 2.5- year medical and dental check-ups. Subjects were divided into 2 groups: test group (n=29, mean age=32.7±5.1) and control group (n=44, mean age=30.2±5.2). For the test group, a chewing function test using chewing gum and a saliva bleeding test employing stimulated saliva as a screening examination, as well as personal education regarding dental care, were conducted by dental hygienists. The instruction was provided to improve the following two items: (1) the use of dental floss or interdental brushes, and (2) regular professional dental check-ups. We used a jaw model, booklets, and dental floss to support the personal instruction. For the control group, a dental examination using a probe and mirror was conducted, and tooth-brushing instructions were provided. Changes in oral health conditions and oral health behavior were evaluated over a 3-month period. The results showed that the rate of subjects who used dental floss or interdental brushes increased from 41.4% (baseline) to 62.1% (3 months) in the test group (20.7% change, P<0.001) compared with 34.1% (baseline) to 47.7% (3 months) in the control group (13.6% change, P<0.001). These results demonstrate that personal instruction with, a screening examination for mothers who bring their children for medical and dental check-ups may improve oral hygiene.
