Root canal morphology of mandibular canines in the Syrian population: A CBCT Assessment

INTRODUCTION: The recent study aimed to assess the root canal morphology of mandibular canines in the Syrian population depending on the cone beam computed tomography (CBCT) images. MATERIALS AND METHODS: A total of 418 fully developed mandibular canines in Syrian individuals aged between 16 and 60 years were included. The presence of at least one mandibular right or left canine with fully developed roots was recorded in each image. The root canal configurations were classified according to the method of Vertucci. The mandibular canines were examined in sagittal, coronal, and axial dimensions. The CBCT images were evaluated by three endodontists with at least 9 years of clinical experience in endodontics. Data were analyzed with descriptive analysis and Chi-square tests using the Statistical Package for the Social Sciences (SPSS) software version 25 (SPSS Inc, Chicago, IL, USA). RESULTS: Out of the 418 mandibular canines, 409 (97.85%) were single-rooted canines while only 9 (2.15%) were double-rooted canines. The most common type of Vertucci in single-rooted canines was Type I (1-1) in the percentage of 95.87% and the least type was Type V (1-2) in the percentage of (0.24%). The Chi-square tests showed no significant association between gender and number of roots (P = 0.64) and gender and root canal configuration in single-rooted canine (P = 0.194). CONCLUSION: Single-rooted with Type I canal configuration was the most common anatomy in mandibular canines in the Syrian population. Incidence of more than one root canal foramen at the end of the single root was detected in one case only.
