This in vitro study analyzed the effect of mechanical loading on microtensile bond strength (μTBS) to dentin of four all‐in‐one adhesives and compared with a total‐etch adhesive system. The tested adhesives were Danville Experimental (an unfilled single‐component adhesive containing a proprietary organophosphate and hydrophobic monomers; Danville Materials), G Bond (GC), Clearfil S 3 Bond (Kuraray), AdheSE One (Vivadent), and Prelude Total‐Etch (Danville Materials). Dentin surfaces were exposed and composite resin (AP‐X, Kuraray) build‐ups were created. The samples were divided into two subgroups and the first subgroups were subjected to mechanical fatigue loading (5 × 10 4 ; 50 Nat 0.2 Hz). Testing was performed after 1 week using a “nontrimming” μTBS test at a cross head speed of 1 mm/min. The data was calculated as MPa and statistically analyzed using Multivariate Analysis of Variance. Multiple comparisons were done using t‐test. Mechanical loading significantly decreased μTBS of the tested materials ( p = 0.000). Prelude Total‐etch showed the highest bond strength values when compared to the tested all‐in‐one adhesives ( p < 0.01). G Bond and Clearfil S 3 Bond showed significantly higher bond strength values than Danville Experimental and AdheSE One ( p < 0.01). © 2009 Wiley Periodicals, Inc.
