    Objective: To evaluate the morphology of root canals in permanent mandibular incisors, using cone-beam computed tomographies available in the Department of Radiology of the School of Dentistry of the University of Cuenca. Materials and methods: A total of 753 tomographic images of permanent mandibular incisors were analyzed. To determine the number of roots, number of root canals and Vertucci classification, each mandibular incisor was analyzed in the three planes of space. To establish the third bifurcation of the root canal, the evaluated dental piece was measured from the amelocementary limit to the apex and divided into equal thirds. Results: 100% of mandibular incisors evaluated presented a root. The prevalence of second root canals was 8.8%, being higher in lateral incisors and in the male sex. The most prevalent Vertucci configuration was type I (91.2%), followed by type III (6.6%), type V (1.5%), type VII (0.4%); Type II configuration (0.1%) and root canal morphology different from Vertucci configuration (0.1%) occurred only in central incisors. The most prevalent bifurcation position was in the middle third (69.7%) in both central and lateral incisors. Conclusions: The total of the sample studied presented a single root. The prevalence of second root canals was higher in males and in lateral incisors. The most prevalent Vertucci configuration was type I, followed by type III. The most prevalent bifurcation position was in the middle third.
