[An oral health scoring system for promoting 8020 achievement in residents].

The present study was undertaken to develop a self-scoring system which can be used by a resident to check lifestyle. The oral health scoring system which we used in Tobishima village, Aichi-ken, was named SAWAYAKA score. A total of 777 subjects were examined. The subjects responded to a questionnaire regarding their past individual lifestyles and dietary habits. Oral health conditions were also examined by dentists. The odds ratio and 95% confidence interval were calculated both from retained tooth numbers and the questionnaire. Questions with significant odds ratio were selected and the partial regression coefficients of quantification II method by Hayashi were calculated. The results are as follows; 1) Eleven questions showed a significant odds ratio between retained tooth numbers and past lifestyle and dietary habits. The questions involved the frequency of snack intake, tooth brushing frequency, having own tooth brush, smoking, drinking, having a hobby, having a family dentist, consulting a dentist before a problem got serious, gum bleeding, swollen gums and toothache caused by sensitivity to cold water. 2) The eleven items were analysed by using Hayashi's quantification II method. 3) The results showed that unswollen gums affected the retention of teeth by the range of 1.240. Toothache caused by sensitivity to cold water affected the retention of teeth by the range of 0.765. Having a hobby affected the retention of teeth by the range of 0.691. 4) The "SAWAYAKA" score was used to select important items, excluding drinking. 5) When results were analysed with the SAWAYAKA score, an average of 9.6 was obtained. It was concluded that the scoring list could be used for checking resident's lifestyles, and for promoting the preservation of more than 20 teeth at the age of 80.
