Abstract: Objective: To describe root canal morphology of mandibular incisors and their variability in Chilean and Belgian samples, using Cone-Beam Computed Tomography (CBCT).Methods: A total of 698 mandibular incisors (353 from Chile and 345 from Belgium) were examined using CBCT images.The anatomical parameters analyzed were number of roots and canals, root canal configuration, presence of septum, tooth length, and radicular length.A descriptive analysis was performed.Differences between the two populations were explored using a generalized estimating equation for quantitative variables.A multilevel regression model was developed for nominal variables.Results: The mandibular central incisor from both samples presented one root, as did the mandibular lateral incisor.One canal was present in most cases for both the mandibular central incisor and the lateral incisor.A type I root canal configuration was also predominant for the central incisor and the lateral incisor.The apical curvature was towards the vestibular direction in most cases, for both samples.A septum was present in 22% of Chilean central incisors and 33% of Belgian central incisors; for the lateral incisors the prevalence of a septum was 21% for the Chilean sample and 38% for the Belgian sample. Conclusion:The anatomical parameters analyzed for the mandibular incisors in Chilean and Belgian samples had statistical differences.The proposed septum classification could be useful for future investigations to determine the length at which a practitioner could expect to find such anatomical variations.
