title: SEM analysis of microstructure of adhesive interface between resin cement and dentin treated with self-etching primer.
abstract: The purpose of this study was to examine the microstructure of the adhesive interface between resin cement and dentin treated with a self-etching primer by SEM in order to clarify the adhesive efficiencies of four self-etch type resin cement systems, Bistite II (BII), Linkmax (LM), Panavia F2.0 (PF), and ResiCem (RC) to dentin. The fluidity and inorganic filler content of these cements were also determined to examine their influences on the adhesion. A hybrid layer with 0.5-1.5 µm thickness and many resin tags could be confirmed clearly at the interface between BII cement and dentin, but was not observed distinctly for the other resin cements. It was suggested that the hybrid layer and resin tags might contribute to the high adhesive efficiency for BII. As the fluidity of cement had been adjusted to be suitable for luting in all cements, it did not significantly influence the adhesive efficiency of cement.
