[Salt fluoridation].

Abstract

The author reports on more than 17 years of trials involving determination of optimum daily requirement of F-, water and salt as well as the F- content of various foods and of urine. On the basis of these physiological data, support is found for salt fluoridation to prevent tooth decay. The results demonstrate that salt fluoridation is not only suitable for community use in automated systems, but is also a universally applicable substance.
