Abstract :OBJECTIVE. The objective of this study was to evaluate the effect of surface conditioning methods on shear bond strength insert ignore into journalissuearticles values(SBS); of a resin composite bonded to CAD/CAM materials. METHODS. The zirconia-reinforced lithium silicate insert ignore into journalissuearticles values(Vita Suprinity VS, and Celtra Duo CD); and hybrid ceramics insert ignore into journalissuearticles values(Vita Enamic, VE and Nacera Hybrid NH); were used. 80 specimens from each material were fabricated following the manufacturer’s instructions and divided into 8 groups according to surface treatments. These were; Gr 1 insert ignore into journalissuearticles values(control, no treatments insert ignore into journalissuearticles values(K););, Gr 2 insert ignore into journalissuearticles values(hydrofluoric acid H);, Gr 3 insert ignore into journalissuearticles values(H+ Silane S);, Gr 4 insert ignore into journalissuearticles values(abraded with 50-micron alumina particles A);, Gr 5 insert ignore into journalissuearticles values(A+ S);, Gr 6 insert ignore into journalissuearticles values(abraded with 30-micron Cojet sand C);, Gr 7 insert ignore into journalissuearticles values(C+S);, Gr 8 insert ignore into journalissuearticles values(S);. The average surface roughness insert ignore into journalissuearticles values(SR); of the specimens was measured. Surface treated specimens were cemented to the resin cement insert ignore into journalissuearticles values(Panavia F 2.0); for testing the adhesion using the shear bond strength SBS test and were tested. Mean SR and SBS results were analyzed by 2-way ANOVA with the material type and surface treatments as the independent variables. RESULTS. The highest surface roughness values were observed in the A and AS groups. Both hybrid ceramics VE and NH showed the highest SR values among surface treatments. The highest SBS values were found usually on the H and HS treated surfaces. The highest values were observed on the CD material in the HS group insert ignore into journalissuearticles values(18,01MPa); and followed by the VE material insert ignore into journalissuearticles values(16,25 MPa); in the CS group. The failure mode for CD and VS materials was found adhesive and cohesive failures and for VE and NH materials adhesive, and mixed cohesive failure was observed. CONCLUSION. The surface treatment showed a significant effect on the SR and SBS values. Although, the SR values of the materials are high in the A and AS group, the highest SBS values were observed in the H and HS treated surfaces.
