Background : Limited evidence exists regarding the effect of carbamide peroxide and casein phospho‐peptide amorphous calcium phosphate (CPP‐ACP) on composite‐enamel bonding. Microshear bond strengths, using either a total‐etch or self‐etching adhesive, to enamel treated with carbamide peroxide and/or CPP‐ACP were investigated. Materials and methods : Twenty‐six extracted human third molars were sectioned into four parts, each being allocated into one of the four groups (n=26): bleach (Polanight, 16% carbamide peroxide), CPP‐ACP (GC Tooth Mousse), bleach and then CPP‐ACP, or untreated (control). The surfaces were bonded with a total‐etch bonding system (Single Bond) or a self‐etching primer system (Clearfil SE Bond) and tested using a microshear test. Results : A significant difference in bond strength was found between bonding systems. SE Bond showed the highest bond strength to untreated enamel (p < 0.05). The microshear bond strength of SE Bond decreased when the enamel was treated with carbamide peroxide, CPP‐ACP or both (p < 0.05). Only combined use of carbamide peroxide and CPP‐ACP significantly affected microshear bond strength with Single Bond.Conclusion: These findings suggest the shear bond strength of resin to enamel using a self‐etching priming adhesive may be affected if the enamel is treated with a bleaching agent or CPP‐ACP.
