Abstract |
The purpose of this study was to analyse the stability and validity of the related factors to the caries incidence according to the duration. The subjects were 249 elementary school students. Among them, the number of male students was 137 (55.0%). In the first year, all subjects gave the responses of the questionnaire composed of demographic variables and oral heath behaviors. They also received oral examination and tests of Dentocult SM and Dentocult LB. In the 2nd-4th year, they received second oral examination for the assessment of caries incidence on permanent teeth. The relation of oral health-related factors with caries incidence was analyzed by chi square method and adjusted Relative Risk (RR). In the caries incidence rate for 1 year, those who had 2 or higher score of dentocult LB was 2.3 times higher than those who had 1 or lower. The caries incidence rate for 2 years was highly associated with caries on deciduous molars and dentocult LB. The caries on deciduous molars showed strong association with the caries incidence for 3 years. It was suggested that the association between the caries incidence and the related factors was different according to the duration. Therefore, dentists could need to consider the visiting period in the education of the risk factors of dental caries. |
