AbstractObjectives: This study was conducted to evaluate the bond durability of three resin cements bonded to bovine dentine over a period of 3 years. Methods: Ten bovine dentine specimens were tested for shear bond strengths with each of the following materials: Panavia 21, BISTITE resin cement, and MASA Bond (experimental resin cement) at 1 day, 6 months, 1 and 3 years after cementation of a composite rod. All specimens were stressed in shear at a crosshead speed of 1 mm min -1 until failure. The means of the bond strengths were compared statistically by two-way ANOVA and Fisher's PLSD test (P < 0.05). The mode of failure was classified after fracture of the bonds by SEM observation. Results for the mode of fracture were analyzed using the Mann-Whitney U-test. Results: The shear bond strengths (MPa ± SD) for different times (1 day, 6 months, 1 and 3 years) were: Panavia 21 (15.2 ± 3.6, 9.3 ± 3.2, 8.5 ± 2.1, 6.8 ± 2.4), BISTITE (15.6 ± 2.8, 11.0 ± 1.4, 10.4 ± 2.2, 9.0 ± 2.7) and MASA Bond (29.6 ± 9.5, 17.5 ± 4.6, 19.6 ± 4.5, 16.1 ± 5.4). Panavia 21 and BISTITE strengths were significantly lower (P < 0.05) at all times compared with MASA Bond, and 1day strengths for all three materials were significantly higher (P < 0.05) than 3 year strengths. Regarding the fracture modes after bond testing, there were statistical differences between the 1 day and the 1 year results for all cements (P < 0.05). Although no Panavia 21 specimen showed complete cohesive failure in the demineralized dentine during the experiment, several BISTITE and MASA Bond specimens showed cohesive fracture in the demineralized dentine. For BISTITE, partially or complete demineralized dentine cohesive failures increased over time. Conclusions: The type of resin cement seemed to have an influence on the long-term durability of bonding to dentine. © 2001 Elsevier Science Ltd. All rights reserved.
