Introduction: This study aimed to determine the root canal configuration of mandibular incisors among a Saudi subpopulation of Qassim region using cone-beam computed tomography (CBCT). Materials and Methods: CBCT images of 94 patients aged from 13 to 69 years with 376 healthy mandibular incisors fulfilling the inclusion criteria were evaluated. The root canal configurations of the examined teeth were recorded in accordance with the Vertucci's classification for each tooth. Data were statistically analyzed. Results: All the examined mandibular incisors had a single root. Type I root canal configuration represented 44.4%, Type II 8%, Type III 44.9%, Type IV 0.5%, and Type V 2.1%. Chi-square tests showed no statistically significant association between the type of tooth and the presence of a second canal (P = 0.177). Conclusions: Within the limitations of this study, it can be concluded that a single root with two root canals of Type III was the most common root canal configuration of the mandibular incisors within a Saudi subpopulation of the Qassim region.
