Abstract
Objective: Understanding root canal anatomyis essential for successful endodontic treatment. This studyanalyzed them orphology of root canals in maxillaryand mandibular anterior teeth in a Brazilian subpopulation using cone-beamcomputed tomography (CBCT). Methods: A retrospective cross-sectional study was conducted with 1,975 CBCT images of anterior teeth from 268 patients. Images were analyzed using Xoran Cat software to asses the number of roots and canal configurations, classified according to Vertucci’scriteria. The chi-square test was applied (p < 0.05). Results: Most teeth (99.9%) had a single root; only 0.1% hadtwo. The most prevalentc onfiguration was Vertucci’sType I (95.8%), followed by Type III (2.8%) and Type II (1%). Types VI and VII were rare (0.3% and 0.1%). No significant association with gender was found (p > 0.05). Conclusion: Anterior teeth showed predominantly simple morphology, with single canals and roots being most common. However, anatomical variations may occur, and clinicians should be aware of them to ensure proper canal location and avoid endodontic treatment failure.
