The aim of this research was to assess the influence of different surface modifications on the bond strength between resin cement and zirconia ceramics. Eighty-four zirconium samples were prepared. Four different surface treatments were applied; nano-alumina coating, 2 minutes gas-phase fluorination, 50 mu m alumina airborne-particle abrasion, and 50 mu m airborne-particle abrasion + 2 minutes gas-phase fluorination. Then specimens were bonded to resin cement. Half of the samples were then incubated in 37 degrees C distilled water for 24 hours. The remaining samples were subjected to thermocycling for 5000 cycles. Shear-bond strength testing was applied at a cross head speed of 5 mm/s. Two-way ANOVA was used in comparison between groups. There is a significant difference between the groups with 5000 cycles and the groups with 24 hours of water cycling. The highest shear-bond strength values were observed in the groups with airborne-particle abrasion + 2 minutes fluorination (27.57 MPa) and nano-alumina coating (26.45 MPa) which were not subjected to thermal cycling. Nano-alumina coating of the zirconia surface and the 2 minutes gas-phase fluorination method following airborne-particle abrasion process increased bond strength between resin cement and zirconia.
