Dental caries prevalence in Texas schoolchildren using water supplies with high and low lithium and fluoride.
The effect of lithium (Li) in drinking water on caries prevalence in seven Texas towns was investigated. Children (life-long residents) aged 12-14 years were examined for caries prevalence, as DMFS, in towns with drinking water Li concentrations ranging from 0.0 to 165 micrograms/L and fluoride (F) concentrations ranging from 0.20 to 1.94 mg/L. A significant negative relationship was found between F in drinking water and DMFS. When corrected for the F contribution, Li in water supplies showed a positive correlation with DMFS.
