Sealing of Developmental Pits and Fissures : III. Effects of Fluoride on Adhesion of Rigid and Flexible Sealers

Abstract
Bovine teeth that were treated with acidulated fluoride before and after etching with phosphoric acid produced adhesive bonds with fissure sealers that were lower than those of untreated controls. Human teeth from an area of high natural fluoridation were shown to be extremely resistant to etching with citric and phosphoric acids.
