The purpose of this study was to develop of selling material for the repair of dental pulp exposure and endodontic perforation because of dental caries and the trouble at the dental treatment. The newly resin material which containing TTCP/DCPA as known two calcium phosphates, with 4-META/MMA resin was produced, and the mechanical properties, the adhesive strength to dentin, the calcification ability using human dental pulp cell were investigated. The results of this study suggested that 4-META/MMA resin containing TTCP/DCPA had a possibility of clinical application of repair material for dental pulp exposure endodontic perforation.

本研究的目的是开发一种可销售的材料，用于修复因龋齿引起的牙髓暴露和根管穿孔，以及牙科治疗中的麻烦。以4-Meta/MMA树脂为基体，制备了含TTCP/DCPA（已知的两种磷酸钙）的新型树脂材料，并对材料的力学性能、与牙本质的粘接强度、人牙髓细胞的钙化能力进行了研究。本研究结果表明，含有TTCP/DCPA的4-Meta/MMA树脂具有作为牙髓外露根管穿孔修复材料临床应用的可能性。
