This study was carried out to investigate the effects of active vs. inactive application of one-step self-etching adhesives on bond strengths to carious dentin. Two one-step self-etching adhesive systems, One-Up Bond F Plus (OB-P, the adhesive was applied actively) and One-Up Bond F (OB, the adhesive was applied inactively), were employed. Human extracted molars with mild occlusal caries were stained with a caries detecting solution and ground perpendicularly to the long axis of the tooth to expose the flat dentin surfaces. The dentin surfaces were classified into sound dentin (SD), caries-affected dentin (CAD) and caries-infected dentin (CID) groups by the degree of staining. Each adhesive system was applied to the surfaces, and a composite resin was built up and polymerized. After immersion in water for24hours, a micro-tensile bond strength test was performed. The treated dentin surfaces and the resin-dentin interfaces with OB-P or OB were observed by SEM. The bond strengths of OB-P for each dentin type were significantly higher than those of OB; however, the bond strengths of both adhesive systems to CAD and CID were significantly lower than those to SD. SEM observation showed that OBP improved the capacity of decalcification and resin-infiltration compared to OB. Thus, the carious dentin adhesive property of OB-P with active application was better than that of OB.
