Abstract


Objectives
Community Water Fluoridation (CWF) was suspended in Ansan city in 2018. The purpose of this study was to inspect the status of caries in the permanent teeth of adolescents and suggest the index as the baseline for cohort study in the CWF suspended area.
Methods
Oral examinations and questionnaire surveys were conducted on adolescents aged 12 years. Of 1,479 individuals, 890 (60.2%) consented to the examinations. Frequency and logistic regression analyses were used to investigate the status of permanent dental caries by demographic, sociological, and health behavioral characteristics. The study was conducted with approval from IRB Kyung Hee University.
Results
The findings reveal gaps in the prevalence of caries among the study sample according to demographic, sociological and health behavioral factors. Rates of untreated caries were higher among adolescents who stayed in the area for a lesser duration, had foreign parents, or had cariogenic drinks more often (p<0.05).
Conclusions
A gap in untreated caries was observed based on demographic, sociological, and health behavioral factors. The findings of the study suggest the need to monitor oral health following cessation of CWF, along with developing alternative programs in the near future.
