Effect of Low Levels of Fluorine Intake on Bones and Teeth

Abstract

Summary

The data here reported show clearly that fluorine additions of 8 to 14 ppm. to a basal diet containing 3 ppm. results in growing rats in increases in the fluorine content of the bones and teeth, which are marked and roughly proportional to the level fed. They show sodium fluoride and bone meal to be equally effective in causing these changes. They suggest that analysis for fluorine is a more sensitive measure than the enamel pigment changes which are also noted at these low levels. The data indicate that the fluorine content of the bones and teeth increases with age during growth.
