Objective: The aim of the present study was to assess the influence of an in vitro aging regime (NaOCl storage) on dentine microtensile bond strength (mu TBS) of five one-step one-bottle self-etch adhesives in comparison with bond strength of two-step self-etch adhesive. Material and methods: Flattened dentine surfaces from 30 bovine incisors were bonded with five one-step one-bottle self-etch adhesives (iBond, Clearfil S3 Bond, AdheSE One F, G-Bond, Optibond all-in-one) and one two-step self-etching adhesive (Clearfil SE Bond). Composite buildups were done with microhybrid resin composite. Bonded samples were sectioned into resin-dentine sticks of 0.8 mm(2) cross section. Randomly selected 20 sticks were tested directly by microtensile bond strength testing machine, whereas another randomly selected 20 sticks were tested after being stored in solution of 10% NaOCl for 5 h. Data were analyzed by two-way analysis of variance (ANOVA) and Tukey's honest significant difference (HSD) tests (p < 0.05). Results: All adhesives exhibited similar dentine bond strength with exception of G-Bond. After NaOCl storage, TBS reduced in all groups significantly. The lowest TBS were found for G-Bond. Rest of one-step self-etch adhesives presented similar mu TBS with two-step self-etch adhesive. Conclusion: Interfaces of resin-dentine bonding are susceptible to NaOCl degradation. The amount of the destruction depends on adhesive system. NaOCl degradation of the nonresin encapsulated collagen fibers might decrease long-term stability of resin bonding with dentine.
