Shear bond strength of one etch-and-rinse and five self-etching dental adhesives when used by six operators Soderholm KJM et al. - The tested etch-and-rinse adhesive did better than the tested self-etching adhesives. The shear bond strength results were also strongly affected by the operator as well as by the interaction between operator and used product. The pooled bond strength values of the different adhesives revealed no difference in bond strength to dentin versus enamel. [more...]
