| Abstract | ||||
| Aim: the aim of this study was to evaluate the micro-shear bond strength of three bonding approaches to enamel namely, two-step etch and rinse bonding approach, one step self-etch bonding approach, and one step self-etch bonding approach with pre-etching. Materials and Methods: Ninety sound human permanent molars were used in this study. The teeth were divided into three main groups according to the type of bonding approaches (n=30). The teeth were embedded in acrylic block, the buccal surface was grounded to expose flat enamel and to receive two composite rods. Specimens were kept in distilled water (37°C for 24h), and submitted to micro-shear testing. Results:The micro-shear bond strength of the etch and rinse bonding approach was the highest whereas the self-etch bonding approach was the lowest and there was a significant difference between the three groups. Conclusions: Etch and rinse-bonding approach is the most predictable technique for bonding of resin composite to enamel, Pre-etching step of enamel plays a positive critical role in improving the bond strength of self-etch bonding approach to enamel. | ||||
