Abstract

Objectives: The aim of this study was to evaluate caries preventive effects of oral health programs composed of pit and fissure sealant and community water fluoridation in Habchon-Up, Habcheon-Gun, Korea. Methods: Dental surveys were conducted on 6 to 14 year old children at Habchon-Up, Habcheon-Gun in 2000 and 2006, respectively. The number of the subjects was 1,957 and 1,263 children in 2000 and 2006, respectively. The percentage of samples among total population aged 6 to 14 years in 2000 and 2006 was 90.6% and 69.2%, respectively. The obtained data from these surveys were analyzed with the SPSS statistical package version 12.0(SPSS Inc., Chicago, IL, USA). The 2006-year dental health data including the prevalence of dental caries and fissure sealants on children's permanent teeth was compared to the 2000-year dental health data and assessed using chi-square test and independent-sample t-test between 2000 year and 2006 year data. Results: DMF rate of 12-year olds was 76.9% in 2000 and it significantly decreased to 44.5% in 2006. DMFT index of 12-year olds was 3.03 in 2000 and it significantly decreased to 1.31 in 2006. The prevalence rate of sealed permanent teeth among 12-year olds was 14.2% in 2000 and it significantly increased to 79.4% in 2006. The caries reduction rate from pit and fissure sealant added by community water fluoridation program was calculated as 56.8% at 12-year olds by the difference of DMFT indexes between 2000 and 2006 year. Conclusions: These results suggests that oral health program composed of pit and fissure sealant and community water fluoridation in Habchon-Up, Habcheon-Gun was very effective in caries prevention and they should be expanded to other area to prevent dental caries among children.
