Abstract

The purpose of this study was to evaluate the cariogenic potential of the permanent teeth by analyzing the caries occurrence at 3 years of age and in the 6th grade of elementary school of the same subject, in a retrospective cohort study. One hundred and sixteen elementary school children in the 6th grade were chosen, whose caries data at 3 years could be obtained from the data file at the regional health center. Eight factors considered to have influence on the caries incidence of the permanent teeth were selected as explanatory variables from a questionnaire concerning life style and analyzed using Quantification Type I analysis. The multiple correlation coefficient was 0.287. When the other factor, caries attack pattern of the deciduous teeth, was added to the explanatory variables, the multiple correlation coefficient increased to 0.355. The caries attack pattern of deciduous teeth showed the strongest influence on the caries of permanent teeth (the partial correlation coefficient =0.181). No interrelation was found in other explanatory variables. These results suggest that the caries prevalence in childhood could be implicated in the caries incidence of permanent teeth.
