An in vitro investigation of microtensile bond strengths of two dentine adhesives to caries-affected dentine

From the data generated by this study it could be concluded that microtensile bond strengths of PBNT/composite restorations to caries-affected dentine in clinical cavities were statistically comparable to those to sound dentine. In the ABF/composite restored group (self-etched), the use of conventional hand excavation appeared to weaken the bond strength to the remaining caries-affected dentine. However, the use of Carisolv™ gel excavation did not compromise bond strengths to caries-affected dentine in either group tested.
