The purpose of this paper is to provide useful information that will enable dentists to predictably shape root canals for three-dimensional obturation of the root canal system. The information is intended to help clinicians better understand when and how to safely use Nickel-Titanium (NiTi) rotary shaping instruments. This article is intended to enhance clinical performance for all dentists who perform root canal preparation procedures regardless of which instruments are chosen and the techniques employed during their utilisation. The guidelines for successful access and the concepts and strategies for canal preparation are discussed. Additionally, the advantages of negotiating and then pre-enlarging the coronal two-thirds of the canal before negotiating and finishing the apical one-third are emphasised. Although a set of endodontic instruments can shape a root canal, this article will also review the importance of irrigants and their role in cleaning the root canal system.
本文的目的是提供有用信息，使牙医能够可预测地塑造根管，以实现根管系统的三维充填。这些信息旨在帮助临床医生更好地理解何时以及如何安全使用镍钛（NiTi）旋转成形器械。本文旨在提高所有进行根管预备程序的牙医的临床操作水平，无论他们选择何种器械以及在使用过程中采用何种技术。文中讨论了成功开髓的指导原则以及根管预备的概念和策略。此外，还强调了在处理根尖三分之一之前，先对根管冠方三分之二进行疏通和预扩大的优点。尽管一套牙髓器械可以塑造根管，但本文还将回顾冲洗液的重要性及其在清洁根管系统中的作用。
