N2 - Purpose: To evaluate the extrusion shear strength of bonding between porcelain and dentin. Methods: The adhesives tested were Prime&Bond NT in both dual-cure and light-cure versions, Scotchbond Multi-Purpose Plus, One-Step and Single Bond. The cements evaluated were RelyX ARC and Enforce. Discs of bovine root dentin 2.5 mm thick had the canal prepared with a standardized taper. Porcelain truncated cones were bonded into the perforations. Cements were tested in dual-cure and self-cure mode. Extrusion shear strength test was performed after 48 hours storage in 37°C distilled water. Data were analyzed by three-way ANOVA/Tukey's test. Results: Bond strength values ranged from 5.5 MPa to 8.9 MPa when cements were tested in dual-cure mode, and from 1.4 MPa to 6.9 MPa when tested in self-cure mode. Scotchbond Multi-Purpose Plus was the only adhesive to present similar results when associated with cements in dual-cure and self-cure modes. For the other adhesives, differences in bond strength from 33 to 76% were observed between dual-cure and self-cure modes.
