Objectives: This study investigates the root configuration and prevalence of multiple canals in mandibular incisors among a Saudi subpopulation in the Al-Madinah Al-Munawara region using cone-beam computed tomography (CBCT). Materials and Methods: The study included imaging data from 929 CBCT scans. All scans were obtained using a CBCT device (Carestream SM 749, Rochester, NY, USA). Each scan was analyzed in two orthogonal planes (axial and sagittal) to explore information regarding tooth identification, the number of roots, and the internal morphology of the mandibular incisors. Vertucci's classification was used to categorize the canal configuration of the mandibular incisors. Statistical Analysis: Data interpretation was performed using SPSS software. Chi-square and one-way analysis of variance tests were applied for data analysis (P < 0.05). Results: Five hundred and twenty-three CBCT scans were excluded according to the set criteria. A total of 1624 mandibular incisors were inspected from 406 CBCT scans. In females, 275 (64.8%) teeth showed Type I configurations, and 125 (29.4%) showed Type III configurations. In males, 563 (46.9%) teeth showed Type III configurations, and 543 (45.2%) showed Type I configurations. In terms of the number of roots, all samples showed single-rooted mandibular incisors. Conclusion: All participants' mandibular incisors had single roots with a high incidence of single-canal configurations. The root canal configuration of the majority of lower incisors showed bilateral symmetry.
