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.
