Fluoridation of public water supplies is a remarkably efficient method of controlling dental caries at the community level. Therefore, in recent years Korean government has a program to expand the area of water fluoridation.The purpose of this study was to prepare the basic data for expansion of water fluoridation. The Piped water fluoride ion concentrations of 1550 areas among the results of drinking water examination by environmental department in 1997, 1998 were examined. On the basis of the result, The fluoride ion concentrations of 20 piped waters of the area in which water fluoridations is to be put´in operation were measured. The piped water fluoride ion concentrations of 3 Naturally fluoridated areas and 11 artificially fluoridated areas and 104 nonfluoridated areas were examined. The fluoride ion concentrations of 24 bottled drinking water were examined. The period of these examinations is from April to June in 1998.
The obtained results were as follows:
1. All the fluoride ion concentrations of 20 piped waters of the area in which water fluoridations is to be put in operation were under 0.3ppm.
2. All the piped water fluoride ion concentrations of 104 nonfluoridated areas were under 0.5ppm.
3. All the piped water fluoride ion concentrations of 11 artificially fluoridated areas were from 0.6ppm to 0.9ppm.
4. The difference of the streams of the piped waters in the nonfluoridated areas were not founded.
5. The fluoride ion concentrations of Jeonlabokdo Jangsugun Janggaemyon and Chungcheong- bokdo
Goysangun Bulgeongmyun were 0.6 ppm. This level is enough to prevent dental caries, but, The fluoride ion concentration of Chungcheongbokdo Chungjusi Judeokeub was 4.5ppm, so this level was
lower. fluoride ion concentrations of 24 bottled drinking water were under 0.4ppm except ~z:.,-onsaemmui and Sparkle(Saemul) and Water King.
