The effect of loading on microTBS of four all-in-one adhesives on bonding to dentin.
This in vitro study analyzed the effect of mechanical loading on microtensile bond strength (microTBS) 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 x 10(4); 50 Nat 0.2 Hz). Testing was performed after 1 week using a "nontrimming" microTBS 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 microTBS 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).
