Root and Canal Morphology of Permanent Maxillary and Mandibular Canines in a Sample of Yemeni Population Using Cone Beam Computed Tomography

Aims and Objective: This study aimed to investigate the external and internal morphological characteristics, including crown shape, root curvature, canal diameter, and root canal configuration, of maxillary and mandibular canine teeth in a Yemeni population using cone-beam computedtomography (CBCT). Materials and Methods: A total of 400 CBCT images (200 maxillary, 200 mandibular) were analyzed from 400 Yemeni subjects (averageage 34). Results: All maxillary canineshad a single root, while 4% of mandibular canineshad two roots (slightly higherin females, but not significantly). Maxillary canines were markedly larger in males (p = 0.001). Most maxillary canines(98.5%) had a single root canal, while 16.5% of mandibular canines had two (significantly higher in males). Using the Vertucci classification, root canal configuration analysis showed that maxillary canineswere predominantly Type I, while mandibular canines displayed more variation. Conclusion: This study provides insights into the morphological characteristics of Yemeni canine teeth. Gender is a significant factor in canine dimensions, with males having larger teeth.
