An oral health survey of mothers who were present at dental examinations for their infants was conducted in four selected prefectures in Japan. The aim of this article was to assess the representativeness of the sample of this survey at different regional levels. The study areas were 33 municipalities selected using a stratified random sampling technique from each prefecture. From November 2005 to March 2006, we conducted oral examinations and questionnaire surveys at 138 sites. The oral examination methodology was the same as that for the national survey of dental diseases in 2005. The questionnaire survey consisted of subjective oral symptoms, knowledge and behavior regarding oral health, lifestyle habits, etc., and most questions were derived from existing national surveys. The number of subjects was 2,786 in oral examinations (response rate: 65%) and 3,301 for the questionnaire survey (response rate: 77%). The average age of the subjects was 31.4 years old. No significant difference was noted regarding the prevalence of dental caries and periodontal disease. The percentages of persons with untreated carious and missing teeth were lower in this survey. Regarding the questionnaire survey, most items did not show a significant difference from existing national surveys. However, the subjects in this survey followed a healthier lifestyle and undertook earlier dental visits. A few survey items were correlated with the response rate in each municipality. Although the survey items which showed significant differences from existing national surveys seemed to be affected by the characteristics of the selected prefectures and the subjects who were mothers of infants, the representativeness of the sample of this survey was considerably high. Therefore, this survey was considered to be an useful nationwide data source in Japan.

Recently, the need for preventive care for frail elderly subjects has been recognized. This study aimed to obtain information about the relationship between the oral status and general health in subjects older than 65 years according to selected items related to the frail elderly. We selected 852 subjects older than 65 years who participated in general health examinations. We conducted personal interviews to obtain information regarding habitual function, physical function, nutritional status, social withdrawal, dementia, and depression in addition to the oral status such as chewing function, feelings of suffocation while eating, and dry mouth. We counted the pertinent number of items for habitual function, physical function, nutrition status, social withdrawl, dementia, and depression. We compared the average number of items with oral function, including chewing ability, feelings of suffocation while eating, and dry mouth. The mean number of items for the disorders was higher in the elderly with the oral disorders assessed. In particular, there was a significant difference in the mean number of pertinent items related to dementia and depression between subjects with compared to those without oral disorders. These findings indicate the presence of a significant relationship between the oral status and general health conditions in frail elderly subjects. Preventive activities to maintain a good general status in frail elderly subjects should focus on improving oral function.

OBJECTIVE: The relationship of the levels of cariogenic bacterial species with periodontal status and decayed root surfaces was investigated in elderly Japanese subjects. METHODS: Three hundred and sixty-eight individuals (each 75 years old) were examined for periodontal status (pocket depth, attachment loss), root surface caries and salivary levels of mutans streptococci (MS) and lactobacilli (LB). RESULTS: Values >4 mm of attachment loss (rAL4) and for average attachment loss (aAL) of sites measured were significantly higher in subjects with LB than those without. Multiple regression analysis also showed a correlation between aAL and rAL4 values with the presence of LB (aAL p = 0.003; rAL4 p = 0.002). Further, multiple regression analysis of interacting factors regarding decayed root surfaces showed that LB carriers had a greater incidence of decayed root surface caries (p = 0.003), while MS and LB levels were correlated to the number of decayed root surfaces (LB p = 0.010; MS p = 0.026). CONCLUSION: Our results indicate that considerable attachment loss elevates the possibility of having LB, thus increasing the risk of root surface caries. It was also found that LB and MS measurements may be useful indicators of decayed root surfaces in elderly individuals with attachment loss.
