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.
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.
This case report provides supplementary data to better understand the complexities of the root canal system of canines.
恒尖牙通常具有一个牙根和一个根管。在恒牙列中，也可能以较低的发生率出现双根双管的尖牙或具有两个牙根和两个单独根管的尖牙。然而，双侧下颌尖牙对称性双根和两个单独根管则较为少见。
本研究报告了一例双侧下颌尖牙对称性双根和两个单独根管的低发生率病例，该病例是基于 CBCT 检查发现的。患者因下前牙不齐就诊于我科，并接受正畸治疗咨询。由于双侧下颌尖牙异常的牙根形态大大增加了正畸治疗的难度，在沟通后，患者最终放弃了正畸治疗。
本病例报告为更好地理解尖牙根管系统的复杂性提供了补充数据。
