| Popis: | Introduction: Nowadays resin cements are commonly used in operative dentistry but the strength of micro- shear bonds of these cements was different in various studies. The aim of this study was to compare the micro-shear bond strength of three resin cements with different mechanisms consisting of maxcem, variolink II and panavia F2.0 to bovine tooth dentin. Methods: Thirty nine longitudinal slices of bovine root dentin were prepared. Specimens were randomly divided into three equal groups. In each group one resin cement was used in cylinders with 1×2mm diameters on each slice. After setting of the cement, micro-shear bond strength was evaluated by a micro-tester device with 0.5mm/min cross head speed. Data were analyzed by ANOVA, Tukey and Bonferroni tests. Results: Micro-shear bond strength of Panavia F2.0, Maxcem and Variolink II was 15.07, 7.33 and 4.97Mpa, respectively. There were significant differences between groups. Conclusion: Micro-shear bond strength of total-Etch resin cements was lower than self-Etch ones. |
