The shear bond strength of the All‐Bond system to dentin and a nonpreeious alloy was evaluated. Eighty human molar teeth (10 per group) were used in the dentin bonding phase of the study. A bond site was prepared in dentin, and both the succinic anhydride modified HEMA and 10 percent phosphoric acid dentin conditioning techniques were evaluated under both wet and dry conditions. Eighty Rexillium III specimens were used in the metal bonding phase of the study. All‐BQnd primer and opaquer were applied to the metal surface, followed by a visible light‐cured composite restorative material. Dentin bond strengths were determined at 24 hours, while metal bond strengths were evaluated both at 24 hours and after thermocycling (2,500 cycles). Separate groups were established for adhesion to both dentin and metal with the composite placed in a plastic matrix or a gelatin capsule. The highest mean shear bond values to dentin were obtained in the groups with the gelatin capsule bonding procedure, where the dentin was treated with 10 percent phosphoric acid and then blotted dry (wet technique) before the bonding procedure (39.99 MPa). These values were higher than the succinic anhydride modified HEMA‐treated group with gentle air drying (wet technique‐29.56 MPa). There was essentially no difference In mean shear bond strengths to dentin when a succinic anhydride modified HEMA dentin conditioner was used with aggressive (dry technique) or gentle air drying (wet technique) [29.56 versus 29.08 MPa], High bond strengths to Rexillium III were obtained when the All‐Bond adhesive system was used in combination with a dual‐care opaquer and a composite restorative material. The adhesive bond values to metal in this study ranged from 23.63 to 25.38 MPa.
