Abstract
ABSTRACT Purpose The objective of this study was to evaluate the influence of the Grander technology on the shear bond strength of total-etch adhesive system Single Bond 2 to dentin. Materials and methods Forty bovine incisors were used. They were sectioned and the buccal surfaces worn down with abrasive paper. Acid etching was performed, and the specimens were divided into two groups (n = 20): Group G1—Single Bond 2 adhesive system (3M ESPE) under normal conditions; group G2—Single Bond 2 adhesive system modified by physical contact for 48 hours with the flexible unit Grander system. The resin composite was inserted with the aid of a metallic matrix over the prepared area. After the mechanical shear test, data were submitted to the statistical t-test (5%). The t-test showed that the results for G1 and G2 were similar (p > 0.05). The mean values (± SD) were: G1—6.66 (± 2.40); G2—5.26 (± 2.15). Conclusion Grander technology did not influence the initial shear bond strength of the Single Bond 2 adhesive system to dentin.
