Abstract
Objectives: The aim of this study is to evaluate the caries preventive effect on primary teeth by the 6- year community water fluoridation program in Ulsan metropolitan city, Korea.
Methods: Dental surveys were carried out in 2005 on 3 to 5 year old children of the fluoridated Namgu in Ulsan and non-fluoridated Haeundae-gu in Busan metropolitan cities. Control group were chosen considering with demographic and socio-economic status. The number of the subjects were 914 children in fluoridated area and 980 children in non-fluoridated area. The obtained data from the survey were analyzed with the SPSS statistical package. The caries preventive effect was estimated by the difference of dft indices and dfs indices between the program and control group.
Results: The df rate of 5-year old children was 61.5% in program group and it was lower compared to 75.3% in control group. The dft index of 5-year old children was 2.72 in prograin group and it was lower compared to 4.12 in control group. The dfs index of 5-year old children was 3.62 in prograin group and it was lower compared to 7.06 in control group. The caries reduction rate of 5-year old children by the community water fluoridation program was estimated as 34.0% by the difference of dft index between program and control group.
Conclusion: These results suggests that the community water fluoridation program in Ulsan Metropolitan City is effective in caries prevention on primary teeth.
