2. OBJECTS
 Investigate the relationships between caries experience
and dental fluorosis at different fluoride concentrations in
drinking water
For set the most appropriate concentrtations for water
fluoridations of public policy

3. METHODS

children
- 4~22 years, 40693 childrens
- dental caries and dental fluorosis investigation
- dental history, using fluoride products
 500ml water sample of surveyed school → fluoride level
