The purpose of this article is to report a successful endodontic treatment of a mandibular first molar with six canals; three root canals in the mesial root, two root canals in the distal root, and one radix entomolaris. The incidence of two anatomical variations presented in this report, middle mesial canal and radix entomolaris, is generally low. Knowledge of the internal anatomy of the root canals and their possible variations, and use of magnification, such as the operating microscope or loupes, can increase the chances of finding additional canals, contributing to the success of endodontic treatment.
本文旨在报告一例下颌第一磨牙六根管的成功根管治疗病例；近中根有三根根管，远中根有两根根管，以及一根远中腭根。本报告中呈现的两种解剖变异，即近中中根管和远中腭根，发生率通常较低。了解根管的内部解剖结构及其可能的变异，并使用放大设备，如手术显微镜或放大镜，可增加发现额外根管的几率，有助于根管治疗的成功。
