Objective: Evaluate the root canal morphology of per- manent mandibular incisors, through the use of cone bean computed tomography (CBCT) in a population of Brazilian southeast region and its relationship with patient age and sex. Methods: A total of 1,484 mandibular incisors of 371 male and female patient`s medical records were analyzed using CBCT. The tomographic images were by the orthopantomograph OP300 tomograph, with voxel of 0.20 mm. The morphology of the teeth was evaluated according to the classification of VERTUCCI, and the effects of sex and age of the patients on the variation in the morphology of these teeth were investigated. Results: All evaluated teeth had only one root. A single canal (Ver- tuccis type I) was detected in 80.7% of mandibular incisors. The second canal was present in 19.3% of the cases, with rates of 1.1% for Type II, 18.1% for Type III, 0.1% for Type IV, and 0.1% for Type V. According to sex, there was no statistical difference (p = 0.890) in mandibular incisor morphology. Within the analyzed age group, individuals aged under 18 years and individuals between 40 and 49 years (28.2% and 26,8% respectively) were statistically significant (p = 0.001) when compared to the other age groups. Conclusions: The most prevalent morphology was Type I of VERTUCCI, followed by Type III, without difference between sex and with a higher prevalence of morphological variation in individuals with less than 18 years and between 40 and 49 years.
