For the success of endodontic treatment, the knowledge of the internal anatomy becomes essential. Objective: to analyze the prevalence of lower incisor canals in a clinical and tomographic analysis. Material and methods: 148 lower incisors were used, measured, and evaluated through periapical radiograph and computed tomography. Results: in relation to the number of canals, 107 teeth (72.3%) presented a single canal, while 41 teeth (27.7%) presented two canals. Of the 41 teeth presenting 2 canals, 3 teeth presented independent canals (2.03%) and 38 teeth had 2 canals that joined at some point of the canal path (25.67%). Conclusion: The prevalence of two canals in the lower permanent human incisors was 27.7%; of these, 2.03% were independent. The main point of root canal union was at the apical third (20.94%). The most commonly found root canal shape was round in cervical third, flattened in middle third, and round in third apical.
