Purpose: The aim of this study was to evaluate the effects of different zirconia surface treatments on the bond strength of two self-adhesive resinous cements (SARC).Methods: Two hundred and eight cylindrical specimens were obtained from Y-TZP zirconia (half with diameter 3.2mm and half with 4.8mm). After sintering and polishing, specimens were divided into four groups (n=26), according to surface treatment: Control (no treatment); Sandblasting (Al2O3 particles); Rocatec (Al2O3 particles, tribochemical silica coating and silane application); Laser (Nd: YAG laser: 20Hz, 100mJ, 0.2J/cm(2)). The surface roughness (Ra) was evaluated after the surface treatments, and the groups were divided into two subgroups (n=13), according to the SARC tested: RelyX U200 and Bifix SE. The 2.2-mm cylinders were bonded to 4.8-mm cylinders and stressed until failure under shear using a universal testing machine. Bond strength and Ra were analyzed using ANOVA, and Tukey's test (=0.05).Results: Surface treatment was significant (p<0.0001), but cement type (p=0.73) was not. Related to roughness, significant differences were found for the treatment type (p<0.0001), with laser being the treatment with higher Ra values.Conclusions: Nd:YAG laser produced a rougher surface and a higher bond strength compared with sandblasting, silicatization, and control groups.
