Shear Bond Strength of MDP-Containing Self-Adhesive Resin Cement and Y-TZP Ceramics: Effect of Phosphate Monomer-Containing Primers

Figure 1

Representative scanning electron microscope images (600x original magnification) of Y-TZP ceramic specimens debonded after cementation with Clearfil SA Luting. (a) Polished Y-TZP; (b) airborne abrasion with 50 μm grain-sized Al₂O₃; (c) Metal/Zirconia Primer, a zirconia primer applied on polished Y-TZP; (d) Metal/Zirconia Primer, a zirconia primer applied on Y-TZP after airborne abrasion; (e) Z-PRIME Plus, a zirconia primer applied on polished Y-TZP; and (f) Z-PRIME Plus, a zirconia primer applied on Y-TZP after airborne abrasion. The regions marked with white stars indicate the remaining resin cements.
