dc.descriptionPurpose: To evaluate the influence of four surface treatments on the bond strength of a self-adhesive resin cement to an yttria-stabilized zirconia (Y-TZP) ceramic material (Lava Frame zirconia). Materials and Methods: Forty plates (8 x 6 x 1 mm) of a Y-TZP ceramic restorative material were randomly assigned to four groups (n = 10) according to the surface treatments: control, no treatment; airborne-particle abrasion with 50-pm Al(2)O(3); coating with an MDP-based primer; conditioning with Rocatec System. The ceramic plates treated with each of the four methods were further divided into 2 subgroups according to the resin cement tested: RelyXTM ARC (ARC, conventional) and RelyXTM Unicem (Ucem, self-adhesive). The resin cements were put into PVC tubes (diameter 0.75 mm, 0.5 mm height) placed on the ceramic plate surfaces. After water storage at 37 degrees C for 24 h, the specimens were submitted to a microshear bond strength (mu SBS) test at a cross-head speed of 1.0 mm/min. Results: The surface treatments significantly influenced the mu SBS (p < 0.05). For the four surface treatments, UCem presented significantly higher mu SBS than ARC (p < 0.05). For both resin cements, the best result was produced by the MDP-based primer: ARC 15.9 +/- 5.0 MPa and UCem 36.2 +/- 2.1 MPa. The highest mu SBS values were presented by UCem on ceramic plates treated with the MDP-based primer (36.2 +/- 2.1 MPa) and Rocatec system (37.4 +/- 2.3 MPa). Conclusion: Irrespective of the surface treatment, the self-adhesive resin cement performed better in terms of bond strength to yttria-stabilized zirconia ceramic than did conventional resin cement.
