| Research Abstract |
The purpose of this study was to evaluate the properties of self-hardening calcium phosphate cement (CPC) for the repair of endodontic perforation. As comparison between CPC and mineral trioxide aggregate (MTA), the mechanical properties, the cell viability and induction of remineralization using human dental pulp cell were investigated. The results of this study suggested that CPC had a possibility of clinical application of repair material for endodontic perforation, though less mechanical properties compared with MTA.
