Abstract
This study evaluated the shear bond strength of a dental hard resin to bovine enamel and dentin with four dual-curing adhesive resin cements and the effect of thermal cycling (5,000 times) on the bond strength. The shear bond strength to bovine enamel was 13-26 MPa, and the strength of resin cement was suggested to affect the bond strength. The shear bond strength to bovine dentin showed 8-16 MPa, and it was also suggested that the bond strength depended on the dentin surface decalcification treatment. The thermal cycling did not markedly affect the shear bond strength in any dual-curing adhesive resin cements except for the dentin specimen with Bistite II.
