Root canal morphology of lower lateral incisors: a CBCT in vivo study
Aim: The aim of this study was to analyze the root canal configuration in mandibular central and lateral incisors in vivo using cone-beam computed tomography (CBCT) imaging in an European population.
Methodology: A total of 500 mandibular lateral incisors from 250 patients were examined using CBCT imaging, previously taken for diagnosis and treatment. The number of roots, root canal system configuration, presence of apical confluences, distance between confluences and radiographic root end, symmetry between left and right elements were recorded and statistically analyzed.
Results: All the examinated teeth presented only one root.
Conclusions: The percentage of Vertucci type II configuration was higher than expected, being more frequent than type II. Other configurations were present but rare.
