Microtensile bond strengths of seven dentin adhesive systems

Abstract

Objectives. The purpose of this study was to evaluate the microtensile bond strengths of seven dentin adhesive systems (Solid Bond, EBS-Multi, PermaQuik, One Coat Bond, Gluma One Bond, Prime & Bond NT/NRC and Clearfil Liner Bond 2V) and their respective fracture modes. Methods. Superficial occlusal dentin of extracted human molars was exposed, finished with wet 600-grit silicon carbide paper, and a block of resin composite bonded with the above adhesives according to the manufacturers' instructions. The teeth were kept in tap water for 24 h at 37°C, sectioned to obtain three or four bar-shaped specimens, which were then shaped to an hour-glass form of 1.2 ± 0.02 mm diameter. The specimens we..
