The knowledge of root canal morphology and the existing anatomical variations is essential for successful endodontic therapy.
This report presents an extraordinary case of unusual tooth morphology involving the bilateral existence of 7 maxillary and mandibular first and second molars with a single root and a single canal in a patient.
Endodontic retreatment of the affected teeth #15, #19, and #18 was performed. Cone-beam computed tomography (CBCT) images confirmed our diagnostic and therapeutic measures after endodontic management of the teeth.
This morphologic variation has not been reported in the literature. The availability of 3-dimensional images further provided the opportunity for the precise description of the anatomy of 7 maxillary and mandibular molars with single roots and single canals.
了解根管形态和现有的解剖变异对于成功的根管治疗至关重要。
本报告介绍了一个特殊的牙齿形态异常病例，涉及一名患者双侧存在 7 颗上颌和下颌第一、第二磨牙，这些牙齿具有单个牙根和单个根管。
对受影响的牙齿 #15、#19 和 #18 进行了根管再治疗。锥形束计算机断层扫描 (CBCT) 图像在对牙齿进行根管治疗后证实了我们的诊断和治疗措施。
这种形态变异尚未在文献中报道。三维图像的可用性进一步为准确描述 7 颗具有单个牙根和单个根管的上颌和下颌磨牙的解剖结构提供了机会。
