Introduction: The study of root and rood canal anatomy is relevant for endodontic treatment. Therefore, knowledge of the root canal morphology is essential to achieve an end- odontic that results in success. However, the professional has limited information of this knowledge and difficult access to the place of performance. Objective: The present study aimed to evaluate the number of the canals of the mandibular incisors, since studies carried out on the subject present a high rate of mandibular incisors with two canals. Methods: In order to evaluate in detail the internal anatomy of the roots of incisors, the accuracy of the cone beam computed tomography in the observation of the root canals in human permanent teeth was evidenced in this study. We analized 97 tomographic images obtained using ORTHO-PANTOMOGRAPH OP 300 (Instrumentarium, Tuusula, FI) of patients who underwent the diagnostic procedure for several reasons. All dental groups were analyzed individually and the morphology was determined according Vertucci Classification (1984). Results: The results observed the Chi-Square statistical test presented higher frequency of Types I and III (Vertucci Criterion) in relation to the other types (p<0.001). Conclusion: It was concluded that computed tomography is the viable resource to aid endodontic practice, especially in complex cases, such as the location of the root canals. The occurrence of more than one canal in central and lateral lower incisors was 23,71% in this study performed in the Brazilian population.
