Abstract
OBJECTIVE To evaluate the influence of different surface treatments on topography, surface roughness, surface energy, and microtensile bond strength stability of resin cement to lithium disilicate glass ceramic. METHODS AND MATERIALS Seventy disc-shaped specimens of IPS e.max Press were divided into seven groups according to the surface treatment: NT - non-treated (control); FSil - hydrofluoric acid (HF) + silane; FPSil - HF + phosphoric acid (HP) + silane; FUSil - HF + ultrasonic bath (U) + silane; FPUSil - HF + HP + U + silane; MEP - Monobond Etch and Prime (MEP); and MEPH - MEP + heating. Topography and surface roughness were evaluated using a 3D laser confocal microscope (3DLCM) and scanning electron microscopy (SEM) and surface energy with a goniometer. The microtensile bond strength (μTBS) was evaluated after storage in distilled water at 37°C for 24 hours and after thermocycling (5,000 cycles, 5°-55° C, 30-second dwell time). Data were analyzed using one-way ANOVA (surface roughness and surface energy), two-way ANOVA (μTBS), Tukey's HSD post-hoc test, and Student t-test (α=0.05). RESULTS FUSil, FPSil, and FSil presented similar and highest surface roughness, whereas NT, FPUSil, MEP, and MEPH showed similar, and lowest, roughness values (p<0.05). FPUSil, FPSil, FUSil, and FSil presented a similar and highest surface energy. NT, MEP, and MEPH showed similar and lowest surface energy. CONCLUSION Only FSil, FPSil, and MEPH maintained bond strength stability after thermocycling, with FPSil leading to less bond strength reduction, suggesting this protocol is more reliable for bonding resin cements to lithium disilicate glass ceramics.
