Abstract

Abstract: PURPOSE: To evaluate the effect of fluoride varnish Duraphat on preventing caries of primary teeth caries, and provide scientific basis for the establishment of oral health care. METHODS: 1140 preschool children aged 3~4 years old were chosen from 25 public kindergartens in Xuhui district of Shanghai by cluster sampling method, they were divided into 2 groups on a voluntary basis with the informed consent of the child's parents. 762 preschool children in Fluoride Varnish group were taken oral examination and used fluoride varnishes every 6 months, 378 preschool children in the control group were without treatment. Oral health instruction was given to all the children. The data of caries prevalence, mean dmft, caries incidence and mean increments of dmft (decayed, missing and filled teeth) of 2 groups were compared. The results were analyzed using SAS 9.4 software package. RESULTS: After 2 years, caries prevalence, mean dmft, caries incidence and mean increments of dmft of fluoride varnish groups were lower than those of control group and the difference was statistically significant (P<; 0.05). CONCLUSIONS: Fluoride varnish Duraphat is effective in decreasing caries incidence and mean dmft increments of primary teeth in preschool children and is worthy to be used widely in Xuhui district.
