Development of 4-META/MMA resin containing TTCP/DCPA with calcification ability

本研究的目的是开发一种用于修复因龋齿和牙科治疗困难而导致的牙髓外露和牙髓穿孔的销售材料。用4-META/MMA树脂与已知的两种磷酸钙TTCP/DCPA复合制备了一种新型树脂材料，并对其力学性能、与牙本质的粘接强度、人牙髓细胞的钙化能力进行了研究。本研究结果提示，含TTCP/DCPA的4-META/MMA树脂有可能作为牙髓外露根管穿孔修复材料的临床应用。

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.
