Purpose: This study evaluated bond strengths of six one‐bottle bonding agents and a control (primer plus unfilled resin) to moist enamel. Materials and Methods: One‐hundred and five bovine teeth were randomly assigned to seven groups of 15. Enamel was etched for 15 seconds with 35% phosphoric acid. Etched enamel was rinsed, and excess water was blotted with tissue paper. Following application of the adhesive, composite resin was bonded using a gelatin capsule technique. Shear bond strengths to enamel were determined using a universal testing machine (Instron Corp., Canton, Massachusetts). Results: Mean bond strengths ranged from 21.9 MPa for OptiBond Solo (Kerr Corp., Orange, California) to 29.6 MPa for Prime & Bond 2.1 (Dentsply/Caulk, Milford, Delaware). Prime & Bond 2.1 had a significantly higher mean bond strength than the other adhesives. CLINICAL SIGNIFICANCE: The results of this study suggest that all of the one‐bottle systems tested should provide clinically acceptable bonding to moist enamel.
