目的：研究纤维粘接蛋白（ｆｉｂｒｏｎｅｃｔｉｎ，ＦＮ）及其复合制剂的盖髓效果。方法：用活体猫牙作直接盖髓实验，并用组织学方法评价盖髓效果。结果：ＦＮ与羟基磷灰石（ｈｙｄｒｏｘｙｌａｐａｔｉｔｅ，ＨＡＰ）的复合制剂（ＦＮ加ＨＡＰ）盖髓成功率最高，而单纯应用ＨＡＰ盖髓成功率最低，分别为８０％、３０．８％，两者之间有显著性差异（Ｐ＜０．０５）。结论：ＦＮ加ＨＡＰ是一种很有希望的复合型生物盖髓剂。
Objective: To study the pulp capping effect of fibronectin (FN) and its combination preparation. Methods: Direct catgut experiment with live cats was used to evaluate the pulp capping effect by histological method. RESULTS: The capping rate of FN plus hydroxyapatite (HAP) composite capsules (FN + HAP) was the highest, while that of HAP capping alone was the lowest (80%, 30.8%, respectively) There was a significant difference (P <0.05). Conclusion: FN plus HAP is a promising compound biological pulp capping agent.
