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.

本研究的目的是评估自硬磷酸钙水泥（CPC）修复牙髓穿孔的性能。作为 CPC 和三氧化二矿物质聚集体 (MTA) 的比较，研究了机械性能、细胞活力和使用人牙髓细胞诱导再矿化的情况。本研究结果表明，CPC虽然力学性能较MTA较差，但具有临床应用牙髓穿孔修复材料的可能性。
