| Abstract | ||||
| Statement of the problem: Debonding is a common cause of failure in zirconia-based restorations. Despite the use of resin cements and surface treatments, the rate of success remains to be questioned. Purpose: The purpose of this study was to evaluate the effect of surface treatment using a silica coating (Co-Jet) method with different luting cements on the shear bond strength to zirconia samples. The hypothesis was that surface treatment with different luting cements will influence the bond strength at the ceramic-cement interface. Materials and Methods: In this study 30 zirconia samples were constructed and underwent surface treatment using a silica coating method (Co-Jet system). Zirconia samples were then bonded to composite samples using different luting agents (Bifix QM, Panavia 2.0 and Multilink Automix). Samples underwent a thermocycling aging process before shear bond strength was tested. Results: The highest shear bond strength was recorded with the Panavia 2.0 group while the lowest was with the Bifix QM group. Conclusions: Within the limitations of this study, the use of a Co-Jet sand silica coating system with Panavia 2.0 showed superior bond strength than the other luting cements. | ||||
