Root and Root Canal Morphology of Mandibular Anterior Teeth in a Jordanian Subpopulation: A Cross-Sectional Cone-Beam Computed Tomography Study

Abstract Numerous studies have explored root anatomy and root canal morphology variations across ethnic groups, but few have focused on the Jordanian population. This study, aimed to assess the prevalence of root anatomy and canal morphology in permanent teeth of a Jordanian subpopulation using cone-beam computed tomography (CBCT). This represents the second part of a four-part series focusing on mandibular anterior teeth. The first part examined mandibular molars, while subsequent parts will investigate the root anatomy and canal morphology of maxillary molars, as well as maxillary and mandibular premolars. CBCT scans of 728 mandibular anterior teeth from patients treated at The University of Jordan Hospital between June and December 2022 were analysed. Canal configurations were categorized according to Vertucci’s classification. Overall, 13.7% of teeth had two canals, most often in lateral incisors (18.3%) and least in canines (8%). Two canines were two-rooted with separate buccal and lingual roots. Vertucci Type I predominated (86.6%). No significant gender-related differences were found. A second canal, though uncommon, should be anticipated when treating mandibular anterior teeth in Jordanian patients.
