Abstract
An adjusted water fluoridation program has been implemented since September 1998 at the Hoeya water treatment plant in Ulsan Metropolitan City. The aim of this study is to evaluate the prevention effect of dental caries on permanent teeth by the adjusted water fluoridation program for four years in Ulsan Metropolitan City.
The dental health survey was carried out by four dentists at primary schools in Ulsan Meopolitan City, Korea in May 2003. The total subjects were 1,894 of benefited and nonbenefited children at aged 641 years. The prevalence of dental caries and fissure sealants orn permanent teeth wereassessed. Chi-square test and independent-samples t-test were usedto analyze the significance of the differences between benefited and non-benefited children by the adjusted water fluoridation program.
The obtained results were as follows;
1. DMF rate on permanent teeth of aged 6-11 years was 44.0% in program group and 49.6% in control group. DMF rate in program group was lower than in control group at aged 6-11 years.
2. DMFT index of aged 641 years was 1.07 in program group and 1.37 in control group. DMFT index in program group was lower than in control group at aged 6-11 years.
3. DMFS index of aged 6-il years was 1.52 in program group and 2.06 in control group. DMFS index in program group was lower than in control group at aged 6-11 years.4. By the difference of D_MFI´ index and DMFS index between program group and control group, the caries
reduction rate on permanent teeth of the program was estimated at 21.9% and 26.2%, respectively.
5. FT rate that is FT index among DMFT index of aged 6-11 years was 53.75% in program group and
44.64% in control group. FT rate of aged 6-11 years in program group was higher than in control group.
6. We could concluded that these results substantiate that a significant reduction in dental caries can be
achieved by the adjusted water fluoridation program and the implementation of the program should be
required to the areas of Ulsan Metropolitan City where are not supplied with the adjusted fluoridated
water.
