Abstract
The purpose of this study is to estimate the preventive effect of water fluoridation on dental caries.
Dental Survey had been done for 537 6-year-old children in fluoridated area and 532 6-year-old children in non-fluoridated area in 1991. After 4 years of follow-up period, the survey was done again for 291 children of fluoridated area and 280 children in non-fluoridated area. DMFS increment of all surfaces, pits and fissures and smooth surfaces during 4 years was calculated and compared between fluoridated and non-fluoridated area.
The obtained results were as follows:
1. Mean DMFS of overall surfaces was reduced 41.5% by water fluoridation.
2. Mean DMFS of smooth surfaces was reduced 48.9% by water fluoridation.
3. Mean DMFS of pits and ° fissures was reduced 37.1% by water fluoridation.
