DOMESTIC WATER AND DENTAL CARIES

VI. THE RELATION OF FLUORIDE DOMESTIC WATERS TO PERMANENT TOOTH ERUPTION

¹ U. S. Public Health Service, National Institute of Health, Bethesda, Md.

1. Public water supplies containing fluorides in concentrations of 2.6 parts per million appear to be associated with delayed permanent tooth eruption in children 12 years of age who have been continuously exposed to the water supply. Significant differences were not observed in those populations using waters containing less than 2.0 parts per million of fluoride (F).

2. The marked difference in dental caries prevalence between populations using fluoride-free domestic waters and those using as much as 1.2-1.3 parts per million of fluorides (F) cannot be explained on the basis of differences in time of permanent tooth eruption.
