Thorough knowledge of anatomical complexities of the root canal system has a direct impact on the effectiveness of canal preparation and filling, and is an essential prerequisite for successful root canal treatment. A wide range of complex variations in root canal anatomy exists, including root canal configuration type, developmental anomalies and minor canal morphology such as accessory canals and apical deltas. Accessory canals and apical deltas have been associated with pulp disease, primary canal infection, canal reinfection and post-treatment disease. The current definitions of accessory canal anatomy are not standardized and potentially confusing. Given their role in endodontic disease and their impact on treatment outcomes, there is a need to have a simple classification of their anatomy to provide an accurate description of their position and path from the canal to the external surface of the root. The purpose of this article is to introduce a new system for classifying accessory canal morphology for use in research, clinical practice and training.
对根管系统解剖复杂性的透彻了解直接影响根管预备和填充的效果，是根管治疗成功的必要前提。根管解剖结构存在广泛的复杂变异，包括根管形态类型、发育异常和副根管等微小根管形态以及根尖三角区。副根管和根尖三角区与牙髓疾病、主根管感染、根管再感染和治疗后疾病有关。目前，副根管解剖结构的定义尚未标准化，可能会造成混淆。鉴于它们在牙髓病学中的作用及其对治疗效果的影响，有必要对其解剖结构进行简单分类，以便准确描述其从根管到牙根外表面的位置和路径。本文的目的是介绍一种新的副根管形态分类系统，用于研究、临床实践和培训。
