Descrição: dc.descriptionThis in vitro study evaluated the effect of surface treatments on the microshear bond strength between zirconia and 2 different resin cements. Thirty sintered zirconia blocks (15.5 × 19.0 × 39.0 mm) were allocated into 10 groups according to 2 factors: surface treatment (control [10% isopropyl alcohol], silica coating, primer, hot etching solution, or glaze) and resin cement (conventional dual-curing [Multilink Automix] or self-adhesive [RelyX U100]). Three cement cylinders (0.7-mm diameter × 1.5-mm height) were made on the surface of each zirconia block. The specimens were stored in water for 6 months at 37°C and then submitted to microshear bond strength tests (n = 9 per surface treatment group). The bond strength data were analyzed statistically with Kruskal-Wallis and Dunn tests (P < 0.05). The contact angle was measured with a goniometer on separate surface-treated disc specimens (n = 2 per group). The greatest mean (SD) bond strength values, regardless of cement type, were reported for the groups with the glaze surface treatment: conventional cement, 13.1 (0.26) MPa; and self-adhesive cement, 20.1 (0.23) MPa. The next greatest mean (SD) values were found in the silica coating groups: conventional cement, 7.94 (0.09) MPa; and self-adhesive cement, 9.8 (0.10) MPa. The self-adhesive cement groups presented the greatest bond strength values, except when the primer surface treatment was applied. The zirconia treated with the hot etching solution presented the greatest mean contact angle, 78.23 (SD 1.34) degrees, and bond strengths that were among the lowest achieved, suggesting that low wettability may have influenced bond strengths.-
