Fluoridation of public water supplies is a remarkably efficient method of controlling dental caries at the community level.. Community water fluoridation results in reduced caries experience accompanied by some degree of dental fluorosis which was now considered as a side effect of it.
The purpose of this study was to estimate the prevalence of dental fluorosis in fluoridated community. 1,496 12-15 year-old students in Kwacheon city which have been fluoridated for 18 months and 1,487 12-15 year-old students in Cheongju city which have been fluoridated for 14 years were examined using the Dean´s criteria for dental fluorosis index. Also, the residents duration of subjects in Cheongju city was collected from their parents.
The obtained results were as follows
1. The prevalence of dental fluorosis was 2.2% in Kwacheon city and 13.7% in Cheongju city.
2. Community Fluorosis Index was 0.03 in Kwacheon city and 0.15 in Cheongju city.
3. The prevalence of dental fluorosis was 18.9% in students exposed before 2
years of age and 9.0% in students exposed after 2 years of age.
