Bond strength and adhesive interfacial micromorphology of self-adhesive resin cements: Effect of reduced times of pre-etching

Abstract

BACKGROUND: Although acid-etching could increase enamel bond strength of self-adhesive (SA) cements, it may lead to negative effect on dentin. The aim of this study was to assess the effect of shortening of phosphoric acid pre-etching duration on enamel/ dentin shear bond strength (SBS) and interfacial microstructure of Panavia SA Luting Plus (PASA) and Bifix SE (BXSE). MATERIAL AND METHODS: <0.001). Adding acid-etching in the three times to both cements similarly improved interfacial adaptation, particularly for enamel. RESULTS: <0.05). CONCLUSIONS: Dentin bond strength, enamel bond strength, pre-etching time, self-adhesive cement.
