Objective:This study aims to evaluate the short-term effects of different plasmas treatments on short-term bond strength of zirconia ceramic surface. Methods:Many pieces of zirconia ceramic slices were sandblasted and randomly divided into 5 groups based on different treatments. Group A,sandblast group;Group B,sandblast + oxygen(O2)plasma group;Group C,sandblast +argon(Ar)plasma group;Group D:sandblast +nitrogen(N2)plasma group;Group E:sandblast+Z-Prime plus group. The zirconia surface topography,contents of carbon and oxygen elements,roughness values,hydrophilicity were determined by scanning electron microscopy(SEM),energy dispersive spectrum(EDS),atomic force microscope(AFM)and water contact angle assay,respectively. And then composite resin columns were prepared and cemented on the pre-treated zirconia blocks with composite resin cement. Initial shear bond strengths(SBS) between zirconia and resin were measured after 24 h water storage. Failure modes were also analyzed. Results:There was no obvious difference in zirconia topography among testing groups. EDS showed that contents of carbon decreased and contents of oxygen increased after zirconia treated by different plasmas. Water contact angle test found that surface energy in groups treated with plasma was significantly improved comparing with group A. SBS test suggested that SBS in group C was similar as group E(P > 0.05),and SBS in both of them were significantly increased compared with other groups(P < 0.05). Conclusion:The short-term bonding strength of zirconia can be significantly increased after treated by Ar plasma.
