Abstract
EXPERIENCE in the United States and elsewhere has shown that the main source for the fluoride intake in man for the partial prevention of dental caries is the water supply. Results from recent investigations in India and Greece strongly suggest that the daily consumption of sea salt by the people of these countries may have been another major source of dietary fluoride. Sea salt was reported to contain 40 p.p.m. of fluoride1. The fluoride content of teeth from India and Greece was found to be considerably high although the level in the water supplies was negligible1,2. In addition, the prevalence of caries in the two countries has been reported to be low1,3.
