Concentration effect of DMSO-dry bonding on the stability of etch-and-rinse bonds.

What Was Tested

The paper reports a study of DMSO (dimethyl sulfoxide, non-peptide solvent), published as a randomized controlled trial.

To examine whether lower dimethyl sulfoxide (DMSO) concentrations would affect long-term bond stability of simplified or multistep water-based adhesives to dry-etched dentin.

Who Took Part

Restored crown segments (n = 5/group) were stored in distilled water for 24 h and sectioned for microtensile bond strength testing.

How the Study Was Run

The design is described as randomized.

Random assignment meant chance, not the researchers, decided who got DMSO (dimethyl sulfoxide, non-peptide solvent) and who got the comparison, which limits bias.

Untreated samples served as control.

Samples were bonded with a two-step or a three-step etch-and-rinse adhesive.

Resin-dentin beams (0.8 mm2) were tested under tension until fracture (0.5 mm/min) after 24 h and one year of storage in artificial saliva at 37 °C.

Nanoleakage evaluation and hybrid layer characterization were performed by SEM.

Bond strength data was examined by three-way ANOVA followed by the Tukey test (α = 0.05).
