Abstract
Introduction: This study measured the contact angles of mineral trioxide aggregate (MTA) and the shear bond strengths of composite resin to MTA with and without acid-etch procedures. Methods: twenty-seven MTA specimens were prepared. The contact angles were measured using 7 specimens before and after acid-etch procedure. The remaining 20 specimens were divided into 2 groups, each with 10 specimens. Acid-etch procedure was done on etched group and not on non-etched group. Then, Scotchbond Multipurpose (3M ESPE, St Paul, MN, USA) was applied and composite resin was built. Shear bond strengths were measured using universal testing machine, and the data were subjected to Mann-Whitney U test. Results: After acid-etching procedure, the average contact angle was significantly lower than that of unetched MTA surface (p<0.05). MTA Specimens with acid-etch procedure showed a significantly higher bond strength than that without acid-etch procedure (p<0.05). Conclusions: Acid-etch procedure improved the wettability of MTA surface and the bond strength between MTA and composite resin.
