Abstract

Objectives: The aim of this study was to investigate the effect of water fluoridation program(WFP) on dental caries prevention in Ulsan, Korea. Methods: The data of control group were extracted from 2012 Korean National Oral Health Survey(KNOHS). Since 1998, WFP was implemented in Ulsan. The subjects were 670 subjects including 10 to 12-years old children in 2009. The control subjects were 4,871 people in non-fluoridated metropolitan cities comparable to Ulsan. The control subjects were selected from 2012 KNOHS. A self-reported questionnaire was completed by the variables including oral health behaviors on daily frequency of toothbrushing, eating snacks and beverages. Oral health examination was carried out by two dentists who received a training in KNOHS with an inter-examiner-agreement. Caries preventive fraction was calculated by the difference of DMFT and DMFS index. The preventive effects of the WFP program were focused on gender, number of fissure sealed teeth, daily frequency of toothbrushing, eating snacks and beverages. Data were analyzed using SPSS $19.0^{(R)}$(SPSS Inc., Chicago, IL, USA) statistical package. Results: DMFT indices of 12-year-old subjects(n=670) in WFP and control population(n=4,871) were 2.11 and 1.23, respectively with an estimated prevention effect of 41.7%. Conclusions: WFP in Ulsan reduced the prevalence of dental caries. WFP should be recommended for the public oral health program in other metropolitan cities.
