Summary
Community water fluoridation significantly reduces tooth decay (DFS) by 0.29 surfaces per year of exposure in adults. This dental caries prevention strategy offers benefits both before and after tooth eruption.
Area of Science:
- Dental Public Health
- Epidemiology
Background:
- Dental caries (tooth decay) remains a significant public health concern.
- Fluoridated water is a widely implemented strategy for caries prevention.
Purpose of the Study:
- To quantify the association between exposure to fluoridated water and caries experience in adults.
- To assess the impact of water fluoridation on decayed, missing, or filled surfaces (DFS).
Main Methods:
- Analysis of oral assessment data from adult populations.
- Statistical evaluation of the relationship between years of fluoridated water exposure and DFS scores.
Main Results:
- Each year of exposure to fluoridated water was associated with a reduction of 0.29 DFS.
- The findings suggest a dose-response relationship between fluoridation exposure and caries reduction.
Conclusions:
- Community water fluoridation is an effective public health intervention for reducing dental caries in adults.
- Fluoridation provides both pre-eruptive and post-eruptive protective benefits against tooth decay.
