Effect of surface treatment and storage on the bond strength of different ceramic systems
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
manufacturer’s 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 Tukey’s 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)
