Objectives: The aim of the present study was to investigate, in vitro, the effect of sandblasting and laser surface treatment on the shear bond strength of Y-TZP with adhesive cement. Scanning Electron Microscope was performed to evaluate the surface morphology changes. Materials and methods: 1. ICE Zirconia blocks: Copy milled Zirconium oxide (Yttrium – partiallystabilized with tetragonal polycrystalline structure). 2. Adhesive resin cement: Dual curing luting composite system Variolink II. 3. Surface treatment was done using: a. Aluminum oxide particles . b. CO2 laser. Results: The SEM image of the untreated zirconia surface showed smooth surface without any morphologic changes. For the laser surface treatment, SEM observations showed that the laser energy promoted smooth blisters-like bubbles with voids surrounded bya flat and porous layer with openings of various diameters. While SEM examination of the sand blasting group showed a completely different appearance. The surface exhibited micromechanical irregularities with shallow pits. Conclusion: Sandblasting and laser application toY-TZP ceramic surface increasingly affects the shear bond strength between cement and Y-TZP ceramics. Surface treatment of the Y-TZP ceramic with CO2 laser prior to cementation provided the highest bond strength between luting resin cement and ceramic.
