Effect of Tooth Whitening and Two Adhesives

The aim of this study was to compare the effects of two adhesives on the shear strength and Adhesive Remaining Index (ARI) of orthodontic brackets bonded to bovine teeth bleached with 10% carbamide peroxide. The adhesives were Prime&Bond 2.1 (acetone-based) and Optibond S (ethanol-based). The 24-hour interval between the end of home bleaching with 10% carbamide peroxide and the bonding of the brackets proved to be sufficient. The groups using Optibond S adhesive showed higher shear strength compared to the Prime&Bond 2.1 adhesive groups.
