Effects of Different Stain Removal Protocols on Bonding Orthodontic Brackets to Enamel

Abstract

The results of the current study indicate higher bracket bond strength to enamel surfaces treated with different stain removal protocols than the clinically acceptable values (5.9-7.8 MPa). However, the more aggressive enamel pretreatment methods should not be considered unless the clinical situation necessitates such action. Postponing the topical fluoride application is advisable to follow the bracket bonding procedure. This action would prevent the negative effect of topical fluorides on bracket-enamel bond strength.
