Root canal anatomy is complex, and the recognition of anatomic variations could be a challenge for clinicians. This case report describes the importance of cone beam computed tomographyic (CBCT) imaging during endodontic treatment. A 23 year old woman was referred by her general dental practitioner with the chief complaint of spontaneous pain in her right posterior maxilla. From the clinical and radiographic findings, a diagnosis of symptomatic irreversible pulpitis was made and endodontic treatment was suggested to the patient. The patient underwent CBCT examination, and CBCT scan slices revealed seven canals: three mesiobuccal (MB1, MB2, and MB3), two distobuccal (DB1 and DB2), and two palatal (P1 and P2). Canals were successfully treated with reciprocating files and filled using single-cone filling technique. Precise knowledge of root canal morphology and its variation is important during root canal treatment. CBCT examination is an excellent tool for identifying and managing these complex root canal systems.
根管解剖结构复杂，识别解剖变异对临床医生而言可能是一项挑战。本病例报告描述了锥形束计算机断层扫描（CBCT）成像在根管治疗中的重要性。一名23岁女性由其全科牙医转诊而来，主要诉求为右侧上颌后牙区自发痛。根据临床和影像学检查结果，诊断为症状性不可逆牙髓炎，并向患者建议进行根管治疗。患者接受了CBCT检查，CBCT扫描切片显示有七条根管：三条近中颊根（MB1、MB2和MB3）、两条远中颊根（DB1和DB2）以及两条腭根（P1和P2）。使用往复锉成功处理根管，并采用单锥充填技术进行充填。在根管治疗过程中，精确了解根管形态及其变异非常重要。CBCT检查是识别和处理这些复杂根管系统的极佳工具。
