The aim of the study was to evaluate the shear bond strengths of composite to dentin using strong, intermediary strong & mild 'self-etch' dentin adhesives and also identify the most probable chemistry & mechanism involved in the action of self-etching systems. The adhesives tested were AdheSE (1voclasr), i Bond (H. Kulzer). Xeno III (Dentsplv). Clearfil SE Bond (Kuraray) and Prompt-L-Pop (3M). Fifty freshly extracted noncarious, unrestored human premolars were taken & the occlusal surfaces of all teeth were ground to expose a flat surface of dentin. After polishing the dentin surface. each tooth was mounted in acrylic resin blocks of uniform dimension. The bonding area on the dentin surface was delineated by a circular outline into which the adhesives were applied following manufacturers directions. Cylinders of resin composite (Z-100) were built on the bonded dentin surfaces in two increments. Following storage in distilled water at 37"C for 24 hours, the specimens were tested for shear bond strength using an Instron Universla Testing Machine at a cross-head speed of 0.5mm / min. The results suggest that 'intermediary strong' selfetch systems demonstrated superior bond strength values compared to the rest. 'Mild' adhesives exhibited values, which were higher than 'strong' but lower compared to 'intermediary strong' systems. The 'strong' self-etch, bonding agents demonstrated the lowest bond strength values compared to all test groups. |
