Title

Effects of Universal and Conventional MDP Primers on the Shear Bond Strength of Zirconia Ceramic and Nanofilled Composite Resin

Pages

  48-56

Abstract

 Statement of the Problem: The clinical success of ceramic depends on the quality of the bond between the Zirconia and resin cement. Purpose: In the present study, the effects of universal and conventional MDP-containing Primers were evaluated on the shear bond Strength of Zirconia ceramic and nanofilled Composite resin. Materials and Method: Thirty blocks of Zirconia ceramic (6mm×2mm) were pre-pared. Then the inner surfaces were air-abraded and divided into three groups (n= 10) as follows: untreated with Primer (control group, I); All-Bond Universal (group II) and Z-Prime Plus (group III). The specimens in each group were bonded with Variolink N cement to cylinders of Composite resin Z350XT. After 24 hour water storage, the shear bond Strength test was performed with a universal testing machine at a crosshead speed of 1mm/ min and bond Strength values (MPa) were calculated and analyzed with one-way ANOVA and post hoc Tukey tests (p< 0. 05). The failure mode of each specimen was evaluated under a stereomicroscope and representative specimens were analyzed by scanning electron microscopy (SEM). Results: The mean shear bond Strength values (MPa) were 7. 58± 1. 62, 17. 51± 1. 34 and 22. 45± 3. 60 in groups I, II and III, respectively. These results indicated that the shear bond Strength were significantly higher in groups II and III compared to the control group (p< 0. 001). Chemical pre-treatment of Zirconia with Z-Prime Plus revealed significantly higher bond Strength than the All-Bond Universal adhesive (p< 0. 002). All the failure modes were adhesive in the control group (I) and when using Primer treatment, mixed failures occurred in 40% and 50% of specimens in groups II and III, respectively. Conclusion: Treatment with both Primers resulted in higher bond Strength values compared to the control group. The use of Z-Prime Plus treatment in combination with air-abrasion procedure resulted in the highest bond Strength.
