Abstract

Background: The permanent canine usually has a single root and a single root canal. A one-rooted canine with two canals or a canine with two roots and two separate canals may also occur at a lower incidence in the permanent dentition. However, bilateral symmetrical mandibular canines with two roots and two separate canals are less common.

Case presentation: This study reported a lower incidence case of bilateral symmetrical mandibular canines with two roots and two separate canals, which was found based on a CBCT examinaton. The patient visited our department and was consulted for orthodontic treatment due to the irregularity of her lower anterior teeth. As the abnormal root morphology of bilateral mandibular canines greatly increased the difficulty of orthodontic treatment, the patient finally gave up orthodontic treatment after communication.

Conclusion: This case report provides supplementary data to better understand the complexities of the root canal system of canines.

双侧对称下颌犬齿，有两个牙根和两个独立的牙道：病例报告和文献综述

背景：恒牙通常只有一个牙根和一个根管。单根犬齿有两个根管或双根犬齿有两个独立根管的情况在恒牙期也可能发生，但发生率较低。然而，双侧对称的下颌犬牙有两个牙根和两个独立的根管的情况较少见：本研究报告了一例发病率较低的双侧对称下颌犬齿双根双管的病例，该病例是通过 CBCT 检查发现的。患者因下前牙不齐到我科就诊并接受正畸治疗。由于双侧下颌犬牙牙根形态异常，大大增加了正畸治疗的难度，经过沟通，患者最终放弃了正畸治疗：本病例报告为更好地了解犬齿根管系统的复杂性提供了补充数据。
