Fluoride concentration in dental plaque of naval recruits with and without caries

Abstract

Plaque samples were evaluated for fluoride concentration, the degree of the fluoride binding and uptake of fluoride from 1 and 225 parts/10 6 F solutions. The plaque of the caries-free individuals contained significantly higher fluoride concentrations, but no difference was found in binding strength between the caries-free and caries-active groups. Uptake of fluoride from a 1 part/10 6 solution was slightly less for plaque of caries-free recruits, but there was no difference between the groups in uptake from the more concentrated solution.
