Abstrakt: Background and Objective: Carbamide peroxide bleaching has been implicated in adversely affecting the bond strength of composite to enamel. The objective of this in vitro study was to evaluate the effect of ethanol-based (Clearfil S 3 bond, Kuraray, Adper Single bond 2, 3M ESPE dental products) and acetone-based (Prime and Bond NT, Dentsply, One Step, Bisco) bonding agents on the shear bond strength of composite to enamel treated with 10% carbamide peroxide bleaching agent.
Materials and Methods: A total of 120 extracted human noncarious permanent incisors were randomly divided into two groups (control and experimental). Experimental group specimens were subjected to a bleaching regimen with a 10% carbamide peroxide bleaching system (Opalescence; Ultradent Products Inc, South Jordan, USA). Composite resin cylinders were bonded to the specimens using four bonding agents and shear bond strength was determined with universal testing machine.
Results: There was no statistically significant difference in the shear bond strength between control and experimental groups with both ethanol-based (Clearfil S 3 Bond and Adper Single Bond 2) and acetone-based bonding agent (Prime and Bond NT and One Step).
Interpretation and Conclusion: The adverse effect of bleaching on bonding composite to enamel can be reduced or eliminated by using either ethanol- or acetone-based bonding agent. Clinical Significances: Immediate bonding following bleaching procedure can be done using ethanol- or acetone-based bonding agent without compromising bond strength.
