Root canal treatment of maxillary molars presenting with complex root canal configurations can be diagnostically and technically challenging.
Nonsurgical endodontic therapy of a left maxillary first molar with three roots and eight root canals was successfully performed. This unusual morphology was diagnosed using a dental operating microscope (DOM) and confirmed with the help of cone-beam computed tomography (CBCT) images.
CBCT axial images showed that both the mesiobuccal and distobuccal root contained a Sert and Bayirli type XV canal, whereas the palatal root showed a Vertucci type II canal configuration.
The use of a DOM and CBCT imaging in endodontically challenging cases can facilitate a better understanding of the complex root canal anatomy, which ultimately enables the clinician to explore the root canal system and clean, shape, and obturate it more efficiently.
上颌磨牙具有复杂根管形态，根管治疗在诊断和技术上具有挑战性。
使用牙科手术显微镜（DOM）和锥形束 CT（CBCT）图像成功完成了左上第一磨牙的非手术根管治疗，该磨牙有 3 个牙根和 8 个根管。这种不寻常的形态是通过牙科手术显微镜（DOM）诊断的，并通过锥形束 CT（CBCT）图像得到了证实。
CBCT 轴位图像显示，近中颊根和远中颊根均包含一个 Sert 和 Bayirli 型 XV 根管，而腭根显示出 Vertucci 型 II 根管形态。
在根管治疗具有挑战性的病例中使用 DOM 和 CBCT 成像，可以更好地了解复杂的根管解剖结构，从而使临床医生能够更有效地探索根管系统并进行清洁、成形和填充。
