Thanatvarakorn O, et al. - The authors performed this study to investigate whether smear layer-deproteinizing could improve bonding of one-step self-etch adhesives to dentin. For bonding to one-step self-etch adhesives, smear layer deproteinizing by hypochlorous acid (HOCl) and Accel application could enhance the quality of dentin. Thus, it resulted in improved microtensile bond strength (μTBS), eliminating hybridized smear layer and preventing reticular nanoleakage formation in resin–dentin bonding interface.
