Abstract


This study evaluated the influence of a metal primer application and the type of resin cement on the bond strength (BS) to yttrium-stabilized tetragonal zirconia, after 24 hours and 6 months of water storage. Zirconia plates (13mmX5mmX1mm) were used in 8 experimental groups (n=10). The micro-shear bond strength test was used in this study. The results were analyzed by three-way Anova (primer application, type of resin cement, storage time) and Tukey test (?=0.05). The primer application did not influence the BS and the resin cement Clearfil SA Cement resulted in higher BS to zirconia. The storage in water for 6 months reduced the BS for all groups.
