Bonded specimens were divided into three groups of ten, and SBSs with bovine dentin were determined after the following treatments: 1) Storage in distilled water at 37°C for 24 h followed by 3,000, 10,000, 20,000 or 30,000 thermal cycles (TC group), 2) Storage in distilled water at 37°C for 3 months, 6 months or 1 year (WS group), and 3) Storage in distilled water at 37°C for 24 h. Differences in SBS values between groups were identified using two-way ANOVA followed by Tukey’sHSD test (α=0.05).Results: SE showed significantly higher SBSs than the other universal adhesives, regardless of the degradation conditions, apart from AB in 30K TC. In comparisons of universal adhesives the degradation conditions, apart from AB in 30K TC. In comparisons of universal adhesives under the degradation conditions, SBS was only reduced in SU after 1 year of WS. The results are shown in the table below.Conclusions: Although universal adhesives have lower SBSs than the two-step self-etch adhesive SE, the results suggest that the dentin bond durability of universal adhesives in self-etch mode is sufficient for clinical use.Reprinted with permission from the Journal of Dental Research, J Dent Res 96 (Spec Iss A):-31-abstract number 3849, https://iadr2017.zerista.com/poster/member/76162, 2017
