The effects of different interventions on 12-year-old children’s permanent teeth caries and filling rate in Shanghai Jiading district

Abstract

Abstract: PURPOSE: To evaluate the effects of different interventions on 12-year-old children’s permanent teeth caries and filling rates in Shanghai Jiading District. METHODS: Six hundred and ninety-one 12-year-old children from 3 middle schools were randomly divided into 3 groups. The filling intervention group received filling of the permanent teeth free of charge for 3 years; The health education group received oral health education for 3 years; The control group only accepted oral examination for 3 years. The data was analyzed with SPSS 20.0 software package for χ²test. RESULTS: On the baseline, the permanent teeth caries rates of 3 groups were 32.10%, 35.56% and 36.84%, and the filling rates were 17.07%, 16.24% and 17.04%, respectively. After 1 year, permanent teeth caries rates of 3 groups were 35.92%, 42.26% and 44.50%, respectively. There was no significant difference among the 3 groups (P>0.05). The filling rates were 93.28%, 61.41%, and 16.67%, respectively. There was significant difference among the 3 groups (P<0.05). After 3 years, permanent teeth caries rates of 3 groups were 37.04%, 48.12% and 58.85%, and the filling rates were 93.66%, 61.51% and 17.28%, respectively. There were significant differences among the 3 groups (P<0.05). CONCLUSIONS: Filling intervention and health education can significantly reduce the permanent teeth caries prevalence rate and improve permanent teeth caries filling rate of 12-year-old children. Furthermore, the effects of filling intervention were more significant than the health education intervention.
