Artificial fluoridation of communal water supplies has resulted in 50% to 60% reductions in dental caries experience accompanied by very little fluorosis. Although vitamin-mineral fluoride supplements also have resulted in significant caries reductions, data are not readily available in the literature in regard to enamel fluorosis in the permanent dentition of children who have received supplements in early infancy. In comparison to estimates of fluoride intake from communal water supplies, the recommended dosage from fluoride supplements results in daily doses that may be two to six times greater, on the average, for the infant less than age 6 months and three times greater for the average 3-year-old. Estimates from both sources bear careful consideration in light of available knowledge and are not necessarily indications for a revision in presently acceptable practice.
