No. of bitstreams: 0 Previous issue date: 2016 The aim of this study was to evaluate the effect of surface treatments on the roughness and bond strength of dental materials containing MDP to zirconium oxide ceramic. Forty square-shaped zirconium-oxide ceramic blocks (Lava Zirconia, 3M-ESPE) were treated as follows: (CT) polished only; (SB) sandblasting (110 mu m aluminum oxide particles) or (SC) silica coating (110 gm particles). Roughness of treated surface was measured using a profilometer (Ra) and by atomic force microscope (AFM). Two resin luting agents were used after silane application: self-adhesive (Rely X U200, 3M-ESPE) and dual cure (Rely X Ultimate, 3M-ESPE). The samples were submitted to microshear bond strength test. The failure analysis was performed. Data were submitted to ANOVA and Tukey test (alpha=0.05). Bond strength results ranged from 20.44 (CT+Ultimate) to 34.37 MPa (SC+ U200) after 24 h and from 12.03 (CT+ Ultimate) to 27.44 MPa (SC+ U200) after 12 months of storage with SC statistically superior to the other treatments. Mean values of roughness varied from 0.07 (Cr) to 0.85 mu m (SC). The both resin luting agents showed similar results to all surface treatment groups. Silica coating provided the best treatment of the ceramic surface. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
