Purpose: Present study investigated microtensile bond strengths (μTBS) of four one-step self-etch dental adhesive systems, two two-step self-etch adhesive systems and one three-step etch-and-rinse adhesive system to pulp chamber dentin. Materials and Methods: The μTBS of seven current adhesives, including one three-step etch-and-rinse (Optibond FL, Kerr, USA), two two-step self-etch (Clearfil SE Bond, Kuraray, Japan; AdheSE, Ivoclar, Liechtenstein) and four one-step self-etch adhesives (Clearfil S3 Bond, Kuraray, Japan; Optibond all-in-one, Kerr, USA; iBond, Heraeus Kulzer, Germany; L-POP, 3M ESPE, Germany) were determined. Adhesives were applied to pulp chamber dentin according to their respective manufacturer's instructions, then μTBS tests were performed. Results: μTBS varied from 29.99 ± 7.82 to 38.15 ± 10.38 MPa. Highest μTBS mean was obtained with Optibond FL and lowest iBond, Heraeus Kulzer, Germany. There were no significant differences among all adhesives. Conclusion: Bonding effectiveness of one-step self-etch adhesive systems to pulp chamber dentin was comparable to two-step self-etch and three-step etch-and-rinse adhesive systems.
