Aim: The aim was to examine root canal morphology of permanent mandibular incisors in an Indian subpopulation using cone-beam computed tomography (CBCT). Materials and Methods: CBCT images of 150 patients with 100 healthy permanent mandibular incisors were evaluated. According to Vertucci's classification, teeth were examined to determine the number of roots, number of canals, and canal configurations. The effects of gender and age on the incidence of root canal morphology were investigated. Results: Of permanent mandibular incisors, 71.64% had a single root with single canal. Mandibular lateral incisors (10.45%) had a higher incidence of the second canal compared with mandibular central incisors (8.34%). A slightly higher percentage of incidence of a second canal was found in males (10%) than in females (5%). Vertucci type I (68.5%) was most common followed by type IV (0.62%) which was the least common. Conclusion: The prevalence of the second canal in mandibular incisors was high but within the range of previous studies performed on different populations. CBCT imaging is an excellent method for detection of different canal configurations of mandibular incisors.
