Abstract
Objectives. We compared the dental caries status of milk and permanent teeth in Ansan, which has an 8-year water fluoridation program, and non-fluoridated Geoje, Korea.
Methods. In 2007, dental surveys were carried out on 5, 6, 8, and 12-year-old children in Ansan (n=974) and Geoje (n=914), Korea. Two cities belong to small and middle sized-cities in Korea by the population size. Survey data were analyzed using SPSS v 12.0 (SPSS Inc., Chicago, IL, USA). Caries prevention was estimated by differences in dmft, dmfs, DMFT, and DMFS indices between the program and control groups.
Results. The dmf rate of 5-year-olds was 57.1% in the program group and 69.8% in controls. The dmft and dmfs index of 5-year-olds in program group was 2.64 and 5.56, respectively. 37.0% for dmft index and 39.6% for dmfs index were lower than controls. The DMF rate of 12-year-olds was 52.1% in the program group and 64.6 in controls. The DMFT and DMFS index of 12-year-olds in the program group was 1.44 and 2.77, respectively, 42.6% for DMFT index and 40.4% for DMFS index were lower than controls. The caries reduction rate of 5-year-olds was 37.0% by based on the dmft index difference. The caries reduction rate of 12-year-olds was 42.6% based on the DMFT index difference.
Conclusions. The community water fluoridation program in Ansan has reduced caries incidence in milk and permanent teeth sufficiently to merit extension to other communities.
