Abstract

Objectives: The water fluoridation program has been implemented since 2008 at the Daesan water treatment plant, Changwon City. The aim of this study is to evaluate caries preventive effect of permanent teeth from community water fluoridation program

Methods: Evaluation surveys were conducted on 8-, 10- and 12-year olds in the fluoridated and non-fluoridated area of Uichang-gu and Seongsan-gu, Changwon City in 2015. The number of the subjects in 2015 was 722 in fluoridated area and 707 in non-fluoridated area. The caries preventive effect of permanent teeth by community water fluoridation was estimated by the differences in adjusted DMFT and DMFS scores between the program and control groups. Cofounders of mean number of fissure-sealed teeth or surfaces, and number of subjects by gender were adjusted to estimate the caries preventive effect of permanent teeth.

Results: The mean DMFT score or DMFS score of children aged 8-, 10- and 12-years adjusted for the number of fissure-sealed teeth or surfaces in fluoridated area were significantly lower than those in non-fluoridated area in 2015. The caries preventive effect of permanent teeth estimated based on the difference of mean DMFT scores adjusted for fissure-sealed teeth, age and number of subjects by gender between control and program group among children was 37.3%.

Conclusions: These results suggest that the caries preventive effect of permanent teeth from water fluoridation program at
Daesan water treatment plant, Changwon City was so high that the water fluoridation program should be developed in other regions in Korea.
