        Objectives: The water fluoridation program has been implemented since 2008, in a region of Geoje City. This study aimed to evaluate the effectiveness of the water fluoridation program on caries prevention in the permanent dentition. Methods: Evaluation surveys were conducted on 8-, 10- and 12-year-old children in the fluoridated and non-fluoridated regions of Geoje City, in 2015. The survey included 834 children from the fluoridated regions and 703 from the non-fluoridated regions. The data obtained from the survey were analyzed using the IBM SPSS statistical package version 23.0. The effectiveness of community water fluoridation in caries prevention was estimated by the differences in the decayed, missing, filled teeth (DMFT) and decayed, missing, filled surfaces (DMFS) scores, between the program and control groups. The mean numbers of fissure-sealed teeth and surfaces were adjusted to reduce their confounding effect. Results: The mean DMFT and DMFS scores (0.69 and 0.91, respectively) of 10-year-olds from the fluoridated regions, after adjusting for the numbers of fissure-sealed teeth and surfaces, were significantly lower than those of the 10 year olds (DMFT: 0.95, DMFS: 1.32) from the non-fluoridated regions. The effectiveness of water fluoridation on caries prevention in the permanent dentition, estimated based on the differences in the mean DMFT and DMFS scores, adjusted for the number of fissure-sealed teeth and surfaces, between the program and control groups of 10-year-old children, was 27.4% and 31.1%, respectively. Conclusions: These results suggest that the effectiveness of water fluoridation on caries prevention in the permanent dentition, in Geoje City was so high that this program should be implemented in other regions in Korea as well.

        The aim of this study was to detect the status of increasing dental caries of school children in Chinhae during the period of an interruption in water fluoridation between March 1992 and September 1997. The dental caries survey was carried out by a dentist from 1992 to 1997 among three primary school children in Chinhae and two primary school children in Mason, Korea. The survey started when subjects were 6 years old. We followed up examinations for six years. The total subjects of Chinhae were 805 at the beginning of this study in 1992 and decreased to 495 by the end of this study in 1997. The caries prevalence on permanent teeth of children in Chinhae were assessed and compared to the caries prevalence in Mason. The obtained results were follows: 1. The rates of children who experienced caries on permanent teeth increased from 16.19%(age 6) to 84.6%(age 11) in Chinhae. Females had much higher caries prevalence than males in permanent teeth at every age. 2. For six years, substantial increases were seen in dental caries among children in Chinhae. DMFT scores were 0.29 at aged 6, 1.52 at aged 8, 2.58 at aged 9, 3.16 at aged 10 and 4.40 at aged 11. Females' DMFT scores were higher than males' DMPT scores at all ages. DMFS scores were 0.41 at aged 6, 2.32 at aged 8, 3.96 at aged 9, 4.93 at aged 10 and 6.94 at aged. Females' DMFS scores were higher than males' DMFS scores at all ages. 3. The percentage of dental caries on pits and fissures among DIvIFS scores in Chinhae were over 90% at all ages. 4. The percents of Decayed Teeth among Decayed, Missing, and Filled Teeth in Chinhae were 87.5% at aged 6 and 77.8% at aged 11. The percents of Filled teeth among Decayed, Missing, and Filled teeth were 12.5% at aged 6 and 22.1% at aged 11. 5. The most caries susceptible teeth among children in Chinhae were first molars. The percentage of sound first molar rapidly decreased from aged 6 to aged 11. Sound upper first molar decreased from 93.0%(age 6) to 38.3%(age 11). Sound lower fast molar decreased from 87.5%(age 6) to 24.9%(age 11). 6. Overall, DMFS scores of only 8-year old children in Chinhae were significantly lower than DMFS scores of 8-year old children in Masan where water fluoridation had not been implemented. 7. The resumed water fluoridation programme should be implemented without an interruption to prevent dental caries of school children.

        도시 초등학교 아동의 영구치우식증실태

        The aim of this study is to assess the caries prevalence on permanent teeth and to collect the basic data for the development of dental health programmes for children in the primary school. The dental caries survey was carried out by a dentist from 1992 to 1997 for 3 primary school children in Masan and Changwon, Korea. The survey started when subjects were 6 years old. The total subjects were 463 at the beginning of this study in 1992 and decreased to 417 by the end of this study in 1997. The obtained results were as follows. 1, Children who experienced caries on permanent teeth increased from 20.3%(age 6) to 88.7%(age 11), Females had much higher caries prevalence than males in permanent teeth at every age. 2. For six years, substantial increases were seen in dental caries. DMFT scores increased from 0.38(age 6) to 4.57(age 11). DMFS scores increased from 0.51(age 6) to 7.12(age 11). Females' DMFT or DMFS scores were higher than males' at every age. 3. Dental caries on pits and fissures among DMFS scores were over 90% from 6-to 11-year olds. 4. The percents of Filled Teeth among Decayed, Missing, and Filled Teeth were 7.3% at 6-year olds and 27.0% at 11-year olds. 5. The most caries susceptible teeth were first molars. The percentage of sound first molars rapidly decreased from 6- to 11-year olds, Sound upper first molar decreased from 91.0%(age 6) to 33.9%(age 11). Sound lower first molar decreased from 84.0%(age 6) to 17.2%(age 11). 6. Community dental health programmes including use of fluoride and fissure sealants should be developed to prevent dental caries and school incremental dental care programme should be developed to treat children' s dental caries at the early stage.
