Abstract :Aim: The aim of the study was to evaluate the shear bond strength insert ignore into journalissuearticles values(SBS); of different resin cements after zirconia surface treatments Materials and Methods: A total of 60 zirconia discs insert ignore into journalissuearticles values(3x7mm); were prepared and divided into 3 main groups according to the surface treatments as control insert ignore into journalissuearticles values(C);, sandblasting insert ignore into journalissuearticles values(SB);, and tribochemical silica coating insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(ME); and multi-system dual-cure adhesive resin insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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.
