| Research Abstract |
This study demonstrated that calcium silicate base materials released Ca and silicon ions, formed Ca- and P-rich surface precipitates and caused the uptake of Ca and Si into human tooth dentin and cariesdentin, all of which indicates their bioactivity. Thus, the degree of bioactivity may differ among the testmaterials tested, most probably due to the difference in the composition and Ca ion release.
