Abstract

Root canal treatment of tooth with aberrant root canal morphology is very challenging. So thorough knowledge of both the external and internal anatomy of teeth is an important aspect of root canal treatment. With the advancement in technology it is imperative to use modern diagnostic tools such as magnification devices, CBCT, microscopes, and RVG to confirm the presence of these aberrant configurations. However, in everyday endodontic practice, clinicians have to treat teeth with atypical configurations for root canal treatment to be successful. This case report presents the management of a mandibular first molar with six root canals, four in mesial and two in distal root, and also emphasizes the use and importance of Cone Beam Computed Tomography (CBCT) as a diagnostic tool in endodontics.

摘要

对根管形态异常的牙齿进行根管治疗极具挑战性。因此，全面了解牙齿的外部和内部解剖结构是根管治疗的一个重要方面。随着技术的进步，使用现代诊断工具如放大设备、锥形束计算机断层扫描（CBCT）、显微镜和根尖片（RVG）来确认这些异常结构的存在势在必行。然而，在日常牙髓病治疗实践中，临床医生必须治疗具有非典型结构的牙齿，根管治疗才能成功。本病例报告介绍了一例下颌第一磨牙有六条根管（近中根四条、远中根两条）的治疗情况，并强调了锥形束计算机断层扫描（CBCT）作为牙髓病诊断工具的应用及重要性。
