ABSTRACT
Aim:
The aim of this study was to evaluate the micro shear bond strength of different ceramic systems IPS Empress 2, Cergogold, In-Ceram Alumina and Cercon - and a dual luting agent.Methods:
Twelve specimens of each ceramic were fabricated and divided according different surface treatments Group 1 No additional treatment was applied to the ceramic surface; Group 2 Ceramics were etched with 9.5% hydrofluoric acid; Group 3 specimens treated with airborne particle abrasion for each ceramic system in accordance with manufacturers instructions (n=20). The tests were performed after 24 h or after water storage for 6 months. Data were then assessed statistically using the 3-way ANOVA and the Tukeys test (P<0.05).Results:
For Cergogold and IPS Empress 2 systems, the treatments performed with airborne particle abrasion and hydrofluoric acid showed no significant differences from each other, and both were superior to the groups without treatment. For Cercon and In-Ceram ceramics, no differences were found among the groups (P<0.05). When the surface was treated with hydrofluoric acid, the highest bond strength was found to IPS Empress 2 in the 6-month storage period (P<0.05).Conclusion:
Lower bond strength values were only observed with IPS Empress 2 ceramic for the control group in the 6-month storage (P<0.05).
