title: Effect of water storage and surface treatment on the microshear bond strength of different luting cements to zirconia.
abstract: This study sought to determine the microshear bond strength of 4 luting cements to zirconia. Zirconia substrates were divided randomly into 16 groups (n = 12), according to the luting cement, surface treatment, and storage time. Matrices were placed onto each zirconia substrate, filled with the cements, and photocured for 40 seconds. Microshear bond strength was determined after storage periods of 48 hours and 75 days; the results were analyzed by ANOVA and Tukey's test (α = 0.05). Surface treatment increased the bond strength to zirconia for 3 of the 4 cements tested. Even after a relatively long period of water storage, the results indicated that surface treatment did not significantly decrease the bond strength values for the same 3 cements.
