How to Improve Oral Fluoride Retention?

This paper reviews current ideas relating to oral fluoride retention after topical applications of various fluoride preparations. The oral fluoride reservoirs, which serve as a store for fluoride, gradually releasing its content into saliva, will be discussed. The present paper also deals with fluoride kinetics in the oral cavity. The answer to the title of the paper has, however, not yet been found but remains a goal for researchers studying caries prophylaxis worldwide in the search for possible ways of increasing and improving oral fluoride retention.
