Description
Summary:	Purpose: The aim of the study was to evaluate the shear bond strength (SBS) of different resin cements after zirconia surface treatments. Materials & Methods: A total of 60 zirconia discs (3x7mm) were prepared and divided into 3 main groups according to the surface treatments as control (C), sandblasting (SB), and tribochemical silica coating (TC). Main groups were divided into two subgroups according to two different resin cements were applied. No surface treatment was applied to the samples in C group. 50μm Al2O3 particles were applied to the samples in SB group for 10 s at a distance of 10 mm under 4 atm. TC group were tribochemically coated with alumina particles. Self-adhesive resin (ME) and multi-system dual-cure adhesive resin (NX3) was applied to the subgroups. After cementation, all samples were tested for SBS. SBS values were statistically analyzed by the Kruskal-Wallis and Mann-Whitney U tests. Results: Regardless of the cement type, SBS values of the surface treated samples were statistically different (p <0.001). Group SB was determined as the group with the highest SBS value. This group was followed by Group C and Group TC, respectively. The SBS values of the samples according to the resin cements and surface treatments were statistically significantly different (p<0.001). SBS values of the samples cemented with NX3 resin cement were found to be higher than the samples treated with ME resin cement. Conclusion: SB increased resin bond to zirconia. It is more advantageous to use multi-system dual cure adhesive cements in zirconia cementation.
