Influence of different surface treatments on zirconia/resin shear bond strength using one-bottle universal adhesive

摘要

This study was designed to evaluate the effect of different treatments on the zirconia/resin shear bond strength (SBS) using commercial one-bottle universal adhesive. Zirconia discs with different surface treatments (blank control; airborne-particle-abrasion; glazing) were bonded to the bovine enamel surfaces using one-bottle universal adhesive. All specimens were tested for SBS (MPa) before and after 10000 thermocycles. Statistically analysis were conducted by using one-way analysis of variance and multiple-comparison least significant difference tests (alpha = 0.05). Airborne-particle-abrasion group showed higher SBS (36.19 +/- 11.86) than control group (14.98 +/- 5.90) and glazing group (10.63 +/- 5.39) (p < 0.05). After thermocycling test, the SBS significantly decreased for control group (8.84 +/- 2.55) and glazing group (6.18 +/- 2.78) while not for airborne-particle-abrasion group (41.5 +/- 7.95). One-bottle universal adhesives combined with airborne-particle-abrasion showed quite high SBS of zirconia/resin, which was appropriate for bonding of zirconia restoration.
