Abstract
The titanium dentin porcelain was synthesized through normal melting-derived route using borate-silicate system. The porcelain was characterized by thermal expansion, X-ray diffraction (XRD), and cytotoxicity tests. The results of XRD showed that the dentin porcelain is homogeneous vitreous and without crystalloids. The thermal expansion coefficient of dentin porcelains increased with the increasing concentration of CaO (or decreased with the increasing concentration of SiO2). The methyl thiazolyl tetrazolium assay results demonstrated that the cytotoxicity of the titanium porcelain was ranked as 0. It was believed that the titanium dentin porcelain synthesized in this research was a biocompatible material and could be used for dental implant materials.
