根管治疗分为根管预备、根管清洗消毒和根管充填,其中根管预备是决定根管治疗成败的关键因素。根管锉的理化性能和设计特点在根管预备中起了至关重要的作用。随着医患对根管治疗疗效的要求不断提高,推动了根管预备方法不断改进、根管预备器械的理化性能更加完善,使得根管治疗水平不断提高,为保存患牙奠定了坚实的基础,本文就根管锉的研究进展做一综述。

Root canal therapy is divided into root canal preparation, root canal cleaning and root canal filling, root canal preparation is the key factor in determining the success or failure of root canal therapy. The physical and chemical properties and design features of root canal files play a crucial role in root canal preparation. With the increasing demand of the patients for root canal therapy, the method of root canal preparation has been promoted, the physical and chemical properties of root canal preparation equipment have been improved, and the level of root canal therapy has been continuously improved, which has laid a solid foundation for the preservation of the affected teeth This article reviews the research progress of root canal file.
