摘　　要：根管预备是根管治疗术的关键步骤。由于根管解剖结构复杂,即使采用现代根管预备器械预备感染根管,根管内壁仍有30%~50%的区域未被切削,残留细菌生物膜。近来推广的XP-endo系列镍钛锉可提高根管清洁效果。该锉由Maxwire合金制成,可随温度发生改变。具有自由灵活性和良好的抗循环疲劳性能,能主动适应根管形态从而进行有效的根管清理。本文就XP-endo系列镍钛锉的物理性能、生物安全性及机械清理性能等进行综述。Root canal preparation is a critical procedure of root canal therapy.Due to the anatomic complexities of the root canal system,even when instrumentation is carefully performed using modern file systems,30%-50% of the canal wall surface area may remain untouched and cover with biofilm.Recently,XP-endo series nickel-titanium instruments are launched to improve the cleaning effectiveness of root canal preparation.XP-endo nickel-titanium instruments are made of proprietary alloy,the NiTi MaxWire,which can react at different temperature levels.XP-endo has incredible flexibility and extreme cyclic fatigue resistance,which can adapt to canal morphology and enhance the efficiency of root canal preparation.In this paper,physical property,bio-safety,and mechanical cleaning of XP-endo series nickel-titanium instruments are reviewed.
