ABSTRACT
AIM:
To evaluate the microshear bond strength of 4 dental adhesive systems after 1 year-water storage. MATERIAL ANDMETHODS:
The sample consisted of 120 cylinders of composite, obtained from 24 bovine incisors, which were divided into four experimental groups G1-Scotchbond Multi-Purpose, G2-Single Bond 2, G3-Clearfil SE Bond, G4-Adper Easy One and two storage times in distilled water T0 - 24h and T1 - 1 year. A bivariate analysis was performed using the ANOVA and Tukey test (α=0.05). Results were evaluated inter-and intra-group in both times.RESULTS:
After 24 hours, G1T0 (39.68A ± 11.55) showed higher bond strength (MPa) followed by G2T0 (22.71B ± 4.07), G3T0 (18.94BC ± 7.29) and G4T0 (13.30C ± 3.94). After 1 year of storage only G1T1 (33.95A ± 6.35) and G3T1 (13.59BC ± 2.63) maintained the bond strength values (p ≥ 0.05), while G2T1 (10.62C ± 4.32) and G4T1 (4.49D ± 2.49) presented a decrease in this values.CONCLUSION:
The hydrophobic two-step adhesive systems maintained the bond strength after 1-year water storage.
