Effect of different air-abrasion protocols on topography, surface wettability and adhesion of MDP monomer-based resin cement to zirconia

This study evaluated the effect of air-abrasion protocols on the topography, surface wettability and adhesion of resin cement to zirconia. Ceramic specimens (N = 49; n = 7) (15 mm × 2 mm) were randomly allocated to seven groups to be treated with: (1) Air-abrasion with 45 μm Al 2 O 3 (A45), (2) 80 μ...

Description
Summary:This study evaluated the effect of air-abrasion protocols on the topography, surface wettability and adhesion of resin cement to zirconia. Ceramic specimens (N = 49; n = 7) (15 mm × 2 mm) were randomly allocated to seven groups to be treated with: (1) Air-abrasion with 45 μm Al 2 O 3 (A45), (2) 80 μm Al 2 O 3 (A80), (3) 30 μm Al 2 O 3 coated with SiO 2 (CoJet) (C30), (4) 30 μm Al 2 O 3 coated with SiO 2 (Rocatec Soft) (R30), (5) 110 μm Al 2 O 3 coated with SiO 2 (Rocatec Plus) (R110); (6) R110R30 (Rocatec) (R110R30) and (7) control, no conditioning (NC). Air-abrasion was performed using a chairside air-abrasion device (2.5 bar, 10 mm, 90 s). Contact angle measurements were performed using goniometry (n = 5). MDP-based dual resin cement (Panavia F2.0) was bonded on four locations after air-abrasion protocols (n = 20 per group). Half of the specimens were tested after 24 h and the other half after thermal cycling (×3000, 5-55 °C). Data were analyzed using 1-, 2-way ANOVA and Tukey's test (alpha = 0.05). Significantly lower contact angle values were observed for groups C30 (62.6 ± 0.91), R30 (61.91 ± 1.05) and R110R30 (61.54 ± 1.02) compared to those of other groups (65.5 ± 0.9-110.61 ± 0.9) (p
