Abstract:
:An in-vitro study was carried out to investigate the effects of contamination of the porcelain surface on the shear-bond strength of a dual-cure composite luting cement to etched, silanated porcelain. Furthermore, the effects of different cleaning regimens were studied. A total of 390 etched, silanated porcelain specimens were randomly divided into 13 groups of 30. Shear-bond strengths were measured for a control group and for specimens contaminated with saliva, die stone, and latex gloves. Freshly contaminated samples were subject to three cleaning regiments; water wash and dry, cleansing with acetone, and cleansing with 37% phosphoric acid gel. Bond strengths to the cleansed surfaces were measured. Weibull analysis and analysis of variance were applied to the results. Saliva and latex glove contamination did not significantly affect shear-bond strength. Die stone contamination markedly reduced the bond strength and cleaning did not restore the bond strength for these specimens. Contact between porcelain veneers and stone models should therefore be avoided. The wash/dry and phosphoric acid cleaning regimens did not significantly improve or reduce bond strengths for contaminated specimens. Acetone cleaning produced a marked reduction in bond strength under all experimental conditions and should not be used.
