Abstract
The purpose of this research was the evaluation of the shear bond strength with applying self-adhesive resin cement that was applied like the resin cements that were used in the clinical testing and applied very thinly in between a tooth and adherend. On a tooth, the wet bonding was applied. Self-adhesive resin cements used in the study were Bifix SE(Bifix), Bis Cem(Bis), ICem(ICem), PermaCem 2.0(Perma), MonoCem(Mono), Rely X Unicem II(Uni), SmartCem2(Smart), Speed CEM(Speed) and U-Cem(UCem). Bovine teeth were used for shear bond strength test. The shear bond strength was measured by using a universal testing machine(Z020, Zwick, Ulm, Germany) with cross-head speed of 0.75 mm/min in semicircle blade. In the shear bond strength of self-adhesive resin cement, Uni and UCem were higher than other self-adhesive resin cement(p<0.05). ICem and Mono were no significantly differences(p＞0.05). On the other hand, Bifix, Bis and Perma exhibited lower shear bond strengths than the other self-adhesive resin cements(p<0.05) and Smart were no significantly differences(p＞0.05). Looking at failure patterns, resin cement was mainly attached to the composite resin block was fractured.
