Opportunistic infections in the oral cavity of the elderly may increase the incidence of systemic disease. The objective of this study was to investigate the differences in the oral bacterial flora between dependent elderly (inpatients) and independent elderly (community-dwelling residents). After multiple variables were taken into account, inpatients had significantly lower detection rates than community-dwelling residents for alpha-streptococci (p < 0.001) and Neisseria (p 0.004), and higher detection rates for Pseudomonas aeruginosa (p 0.024), methicillin-resistant Staphylococcus aureus (MRSA) (p 0.011) and Actinomyces spp. (p 0.005). Among inpatients, the requirement for a high degree of care was related negatively to detection of alpha-streptococci, but was related significantly to detection of P. aeruginosa (p 0.018) or MRSA (p 0.004). Tube-fed inpatients had a significantly lower detection rate for alpha-streptococci (p 0.041) and a higher detection rate for P. aeruginosa (p 0.004) than those who did not require tube feeding. Inpatients with a history of antibiotic use had a significantly lower detection rate for alpha-streptococci (p 0.049) and a higher detection rate for MRSA (p 0.007) than those without a history of antibiotic use. The detection rates for P. aeruginosa or MRSA in inpatients without alpha-streptococci were higher than in inpatients with alpha-streptococci after controlling for age and gender (P. aeruginosa, p 0.006; MRSA, p 0.001). Overall, detection of alpha-streptococci had an inverse correlation with the detection of P. aeruginosa and MRSA in the oral cavity and is likely to be an indicator of pathogenic bacterial infection.

Aim: The purpose of this study was to evaluate the relationship between periodontal disease and general health status in community-dwelling elderly using serum albumin concentration as a criterion index of the severity of an underlying disease and nutrition status.
Methods: Serum albumin level was detected by the bromcresol green albumin (BCG) method and the data for serum albumin were available in 368 subjects aged 75 years. Pressure-sensitive probes were used to measure loss of attachment (LA) on six sites of all teeth present. Information relevant to gender and smoking habit was obtained by means of a personal interview, while body mass index (BMI) and biochemical serum markers were investigated.
Results: Serum albumin concentration ranged from 3.2 to 4.8 g/dl with a mean of 4.1 +/- 0.2. More than 70% of subjects had at least one site with LA 6+ mm, while 91 exhibited 10% or more sites with LA 6+ mm. Using a multiple regression analysis, we found that sites of LA 6+ mm had a significant effect on serum albumin level (correlation coefficient=-0.14; p < 0.05), which was independent of the other covariates.
Conclusions: The findings of the present study indicated that there might be an inverse relationship between periodontal disease and serum albumin concentration in these elderly subjects.

This study aimed to determine whether the long-term use of a fluoride mouthrinse affects the salivary levels of mutans streptococci. Two hundred and fifteen schoolchildren (aged 9-10 years) participated. One hundred and forty-nine of these children had used a fluoride mouthrinse since 5 years of age at nursery school, and the remaining 66 children had not. DFT (decayed and filled teeth) was recorded, and the salivary levels of Streptococcus mutans and Streptococcus sobrinus were measured using mitis salivarius bacitracin agar. The group that had used a fluoride mouthrinse had a significantly lower prevalence of both S. mutans and S. sobrinus (p = 0.038) and a significantly lower DFT score (p = 0.001) than the other group. Using logistic regression analysis including caries experience at baseline as a dependent variable, the odds ratio of carrying S. mutans alone was 8.0 (p = 0.066) and that of carrying both S. mutans and S. sobrinus was 16.5 (p = 0.022) in the group that had not used the fluoride mouthrinse. Children carrying both S. mutans and S. sobrinus had a higher caries incidence in 1 year than the others, with odds ratios of 5.73 ( p = 0.067) in the group with a fluoride mouthrinse and 3.47 (p = 0.035) in the group without it. These results show that the long-term use of a fluoride mouthrinse is associated with reduced salivary levels of mutans streptococci and this bacterial reduction may partly contribute to the suppression of dental caries in children using a long-term fluoride mouthrinse.

Objective: The main objective of this study was to determine the relationship between bleeding on probing (BOP) and periodontal disease progression in community-dwelling older adults. Methods: A 3-year longitudinal study was carried out in 229 non-smoking healthy older adults aged 70 years. Using pressure-controlled periodontal probes, BOP, pocket depth and attachment level at 13,289 sites were measured annually. Periodontal disease progression was defined as an increase in attachment loss of ≥ 3 mm from the baseline to the final examination. The backward stepwise logistic regression analysis was performed to assess the relationship between the total number of sites with BOP in the four examinations and periodontal progression. Results: Logistic regression analysis showed that the odds ratios of BOP frequency for periodontal disease progression ranged from 1.4 to 6.2 after controlling for pocket depth ≥ 4 mm at baseline, number of missing teeth, jaw type and tooth site. Conclusion: Increasing frequencies of bleeding might increase the probability of periodontal disease progression in community-dwelling older adults. © Blackwell Munksgaard 2005.

Tooth loss and osteoporosis may share common aetiologic agents which influence the process of both diseases. The purpose of this study was to evaluate the relationship between bone mineral density (BMD) of the os calcis and the number of remaining teeth, controlling the known confounding factors. Among all 70-year-old inhabitants in Niigata City, Japan, 600 people were selected randomly in order to have approximately the same number of each gender. We analysed 460 subjects. We evaluated the BMD of the os calcis using an ultrasound bone densitometer, then we counted the number of remaining teeth excluding the third molars. Stiffness is a clinical index which is calculated by the spread speed of supersonic waves. To monitor the general health condition of the subjects, serum levels of disease markers and smoking habits were also investigated. The mean number of remaining teeth for the osteopenia group (OG) and the no-osteopenia group (NOG) was 15.97 ± 9.98 and 18.31 ± 8.06, respectively in females, and 16.32 ± 9.93 and 18.12 ± 9.33, respectively in males (OG versus NOG, P = 0.047 by two-way ANOVA). In addition, stiffness was significantly associated with the number of remaining teeth (CV = -0.157, P = 0.005) using linear multiple regression analysis adjusted by four other variables. In this study, there was a significant relationship between the number of remaining teeth and BMD of the os calcis. © 2005 Blackwell Publishing Ltd.

Background: A Japanese population residing in the same area may be suitable for evaluation of the association among IgG subclass levels, smoking status, and periodontal disease due to similar racial and environmental factors, as these factors can interact to influence serum IgG subclass levels. The present cross-sectional investigation attempted to examine the influence of serum IgG subclass levels and smoking status on periodontal condition in a population of elderly Japanese subjects. Methods: Elderly individuals (N = 451, age, 71 years) residing in Niigata City, Japan participated in the present study. Clinical evaluations, which consisted of probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), and calculus, and serological determinations including serum IgG subclass levels and anti-Porphyromonas gingivalis fimbriae IgG subclass titers were conducted. All participants were asked to complete questionnaires regarding smoking status and were then divided into one of three groups: never smoker, former smoker, or current smoker. Results: Distributions of the number of teeth did not differ significantly across the groups. The proportion of sites with CAL ≥4 mm (%CAL4) in current smokers was significantly higher in comparison with never smokers. Multiple linear regression analysis revealed that %CAL4 was influenced by number of teeth, serum IgG2 levels, gender, and smoking status (R2 = 0.253, P &lt
0.001). The effect of IgG2 was greater than that of smoking status. Distribution of IgG2 was not significantly different across the three groups. Conclusion: These data indicate that serum IgG2 levels influences periodontal conditions in an elderly Japanese population independent of smoking status.
