The Purpose of this study was to investigate the effects of NanoCDHA on the apatite formation ability of tricalcium silicates (Ca3Sio5, C3S) and the mechanism of apatite formation on C3S pastes. Different amounts of NanoCDHA were mixed in the raw materials during the synthesis process of C3S. The apatite formation ability of the NanoCDHA doping C3S was examined by soaking for period of 1 to 5 days setting pastes in simulated body fluid (SBF). The pH values, structural and morphological variations of the pastes were examined during soaking in SBF and determined by XRD and SEM. With the addition of NanoCDHA, the initial crystalline apatite formation time of the pastes was decreased extremely. C3S doped with 2 wt% NanoCDHA showed the better ability to induce the formation of apatite. The results indicated that NanoCDHA doping C3S has better in vitro bioactivity and may be used to prepare novel bone and dental cement.
