Influence of chlorhexidine concentration on microtensile bond strength of contemporary adhesive systems

The purpose of this study was to investigate the influence of chlorhexidine (CHX) concentration on the microtensile bond strength (μTBS) of contemporary adhesive systems. Eighty bovine central incisors were used in this study. The facial enamel surface of the crowns was abraded with 600-grit silicon carbide paper to expose flat, mid-coronal dentin surfaces. The tested materials were Scotchbond Multipurpose (SMP), Single-Bond (SB), Clearfil SE Bond (CSEB) and Clearfil Tri S Bond (CTSB). All the materials were applied according to manufacturer's instructions and followed by composite applicatio...
