| 520 | _aThis work was aimed to study the effect of alumina particle size, blasting pressure as well as thermocycling on the shear bond strength between zirconia ceramic and adhesive resin cement. Sixty five zirconia ceramic discs (Cercon® Smart ceramics) were utilized. A total number of 50 discs were divided into 5 groups (S1)-(S5) (n = 10). Those discs were air abraded using different blasting pressures (0.05 MPa and 0.25 MPa) and different alumina particle sizes (50æm and110æm). The other 15 zirconia discs were selected as representative specimens for surface characterization via scanning electron microscope, obtaining crystalline phase identification by using X-ray diffraction and detecting average surface roughness (Ra) via environmental scanning electron microscope (ESEM). SEM was performed to observe surface topography after sandblasting on 5 representative specimens from each of the main groups (S1)-(S5). XRD was utilized to detect tetragonal monoclinic transformation after air abrasion. ESEM was utilized to detect average surface roughness (Ra) on representative samples from each group. Shear bond strength testing was performed on 50 zirconia specimens after cementing to resin composite cylinders using a self adhesive resin cement rely{u2122} X Unicem | ||
