Abstract: Objective To evaluate the effect of Er:YAG laser and plasma treatment on the bond strength between zirconia and resin cement. Methods Thirty-six zirconia disks were made and randomly assigned to one of the following six groups (n=6):group A, control group;group B, sandblast treatment group;group C, Er:YAG laser group;group D, Ar plasma group;group E, sandblast+Ar plasma group;and group F, Er:YAG laser+Ar plasma group. The surface of each zirconia specimen was tested using a contact angle meter and scanning electron microscope, and the shear bonding strength was then calculated. Results Irregular pit-like structures were scattered on the surface of group C, and the roughness values of group B were significantly increased compared to those of group A (P<0.05). There was no difference in surface morphology between groups D and A, and the hydrophilicity of group D was significantly increased compared to that of group A. The hydrophilicity and shear bonding strength were similar in group E (P>0.05), and they were significantly higher than those of the other groups (P<0.05). Conclusion Both Er:YAG laser and Ar plasma treatment alone can improve the bonding strength between zirconia and resin cement;however, combined Er:YAG laser and Ar plasma treatment yields better results than treatment by each method alone.
Key words: zirconia, Er:YAG laser, plasma, shear bond strength
