| Popis: | To evaluate the effect of three surface treatments and two resin cements on microtensile bond strength of zirconia to dentin. Sixty human molars were embedded in acrylic resin and sectioned 3 mm below the occlusal plane. Teeth specimens and sixty zirconia specimens were randomized into 3 groups according to the following surface treatments (n=20): no treatment (control), sandblasting and silane application (SB+SI), sandblasting then silica coating and silane application (SB+SC+SI). In each group, half of the ceramic-tooth assemblies were cemented with PanaviaTM F (Kurary Dental), the rest with RelyX Unicem (3M ESPE). All specimens were cut into microtensile sticks that were loaded in tension until failure. Data were analyzed using two-way ANOVA and Tukey’s HSD test (α=0.05). The SB+SC+SC group presented higher values than SB+SI and the control group (P |
