Outline of Final Research Achievements

The purpose of this study was to identify regional differences in a prevalence of dental caries among children.The subjects were 3,243 children of one and a half or three years old, who participated in health checkups at Kitakyushu city. We examined a prevalence of dental caries among children of one and a half or three years old by administrative districts. Furthermore, we evaluated the relationship between a prevalence of caries at age of three and a lifestyle at the age of one and a half by administrative districts, employing logistic regression analysis. Then, we evaluated a prevalence of multiple dental caries among those who had one or more caries at the age of three as well.There were significant differences in a prevalence of multiple dental caries among those who had one or more caries at the age of three by administrative districts in Kitakyushu city. The odds ratio (95%CI) of multiple dental caries among children in C-district to A-district was 3.47 (1.47-8.23).
