    ObjectivesTo investigate the prevalence of additional canals and the occurrence of oval canals in apical third area of mandibular permanent incisors of Saudi sub-population.MethodsThis study was conducted from November 2020 to May 2021 at College of Dentistry, Qassim University. For the investigation purpose of this study, 314 scans were analyzed within the age limits of 13 to 70 years. The root canal morphology, presence of oval canals, number of roots, and prevalence of various canal configurations based on age, gender and bilateral symmetry were recorded. The obtained data was statistically analyzed using SPSS software.ResultsThe mandibular central incisors (CI) exhibited, significant difference between Type-I, II, III and IV canal configurations and Type-I, II, III and V canal configurations (p < 0.05). For the mandibular lateral incisor (LI), significant difference was found between Type-I, II, III, IV and VII canal configurations (p < 0.05). The cumulative prevalence of oval canals in mandibular incisors was found to be 46.6%. For both mandibular CI and LI, the prevalence of Type-I canals was significantly higher in males as compared to females (p < 0.05). Conversely, significantly higher prevalence of Type-III canals was noted for females as compared to males (p < 0.05). No significant difference was found in the prevalence of different canal configurations on the left and the right side of the mouth.ConclusionIn this study, multiple canals were prominently recognized with Type-III mandibular incisors dominating this feature. Oval canals were predominantly found in single canal especially Type-III. This research suggests variability in canal morphology among different populations. Knowledge of these aberrant canal anatomies is useful for the clinician to achieve a favorable endodontic outcome.Copyright: © Pakistan Journal of Medical Sciences.
