Abstract

Fluoridation of public water supplies is a remarkably efficient method of controlling dental caries at the community level. But 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 estimated the prevalence of dental fluorosis and level of water fluoride between fluoridation group and control group for total 3,022 students of 6-15years old in Yeosu city which have been fluoridated for 5 years. The obtained results were as follows: 1.DMF rate of fluoridated area was lower than controlled area for mean 10.7%. 2.The prevalence of questionable dental fluorosis was 3.7% in fluoridated area, 3.5% in controlled area. and very mild dental fluorisis was 0.3% in fluoridated group, 0.4% in controlled area. 3.The prevalence of dental fluorosis in fluoridated area was 4.3% in girls,and 3.1% in boys. 4.The level of water fluoride was 0.53ppm in fluoridated area and 0.17ppm in controlled area.
