The root canal anatomy of mandibular second molar teeth is known to be highly variable. Whilst the most frequently seen configuration is two mesial canals and one distal canal, other variations such as four canals, two canals, and C-shaped canal system do also exist. This case report describes the diagnosis and management of unusual root canal configuration of a mandibular second molar, with one canal in a single conical root, using the contemporary advancements in endodontics. Following clinical and radiographic examinations of the case, a diagnosis of symptomatic irreversible pulpitis with symptomatic apical periodontitis of tooth #47 was established, and root canal treatment followed by composite buildup and crown were planned. Clinicians should be aware of the different anatomic variants each tooth may exhibit. Furthermore, clinicians need to possess the proper knowledge and skills that allow them to utilize the diagnostic and therapeutic tools available at their disposal in order to optimize the quality of care provided to their patients.
下颌第二磨牙的根管解剖结构具有高度变异性。虽然最常见的形态是两条近中根管和一条远中根管，但也存在其他变异情况，如四条根管、两条根管以及C形根管系统。本病例报告描述了下颌第二磨牙异常根管形态（单根单根管）的诊断和治疗，采用了当代牙髓病学的进展。对该病例进行临床和影像学检查后，确诊为47号牙有症状的不可逆性牙髓炎伴症状性根尖周炎，并计划进行根管治疗，随后进行复合树脂充填和全冠修复。临床医生应了解每颗牙齿可能呈现的不同解剖变异。此外，临床医生需要具备适当的知识和技能，以便能够运用手头可用的诊断和治疗工具，从而优化为患者提供的护理质量。
