Effect of Different Surface Treatment on the Shear Bond Strength between Yttria-Tetragonal Zirconia Polycrystal and Non-10-Methacryloyloxydecyl Dihydrogen Phosphate-Containing Resin Cement

Abstract

Purpose: To evaluate the effect of different surface treatment methods (yttria-tetragonal zirconia polycrystal [Y-TZP] primers, air-abrasion, and tribochemical surface treatment) on the shear bond strength between (Y-TZP) ceramics and etch-and-rinse non-10-methacryloyloxydecyl dihydrogen phosphate (MDP)-containing resin cements. Materials and Methods: Y-TZP ceramic surfaces were ground flat with 600-grit silicone carbide abrasives paper and then divided into seven groups of ten. They were treated as the following: untreated (control), Monobond Plus (IvoclarVivadent), Z-PRIME Plus (Bisco Inc.), ESPE Sil with CoJet (3M ESPE), air-abrasion, Monobond Plus with air-abrasion, and Z-PRIME Plus with air-abrasion. The surface of Y-TZP specimens was analyzed under a scanning electron microscope (SEM). Non-MDP-containing cements were placed on the surface-treated Y-TZP specimens. After thermocycling, shear bond strength test was performed. Bond strength values were statistically analyzed using one-way analysis of variance and Student-Newman-Keuls multiple comparison test (P Result: The Z-PRIME Plus treatment in combination with air-abrasion produced the highest bond strength (14.94±1.70 MPa) followed by Monobond Plus combined with air-abrasion (10.70±1.71 MPa), air-abrasion (10.47±1.60 MPa), ESPE Sil after CoJet treatment (10.38±0.87 MPa), Z-PRIME Plus application (10.00±1.70 MPa), and then Monobond Plus application (9.25±0.86 MPa). The control (6.70±1.49 MPa) indicated the lowest results (P Conclusion: The shear bond strength between the Y-TZP ceramic and the non-MDP-containing resin cement was the greatest when the surface was treated with air-abrasion and MDP-containing Z-PRIME Plus primer.
