Abstract

Objective: evaluate the root canal morphology of mandibular first premolars using Computed Tomography scans. Method: Two observers analyzed 311 tomographic images, and 486 teeth were evaluated. The variables studied were the sex, the types of teeth, the number of roots, the root shape, the number and shape of each canal in the cervical, middle and apical thirds, the tooth length, the Vertucci’s classification and the presence of C-shaped canals. Results: A single canal was found in 74.9% of the sample, with Vertucci type I being the most frequent. Bifurcations occurred in the middle thirds (19.5%) and apical (17.1%) and the occurrence of "C" canals was rare (0.4%). Conclusion: The presence of more than one canal had a statistically significant association with the canal format and the sex. The internal anatomy of these teeth is complex, which can make endodontic treatment difficult.
