Abstract

Background: The purpose of the study was to analyze mandibular anterior teeth in a Polish population and determine the symmetry of root and root canal morphology between the right and left side using cone-beam computed tomography scanning.

Materials and methods: From 111 cone-beam computed tomography (CBCT) examinations, 303 pairs of equivalent mandibular anterior teeth were analyzed on the right and left sides to evaluate symmetry.  Axial, sagittal, and cross-sectional slices with a thickness of 0.2–0.25 mm were used. The number of root canals and their internal patterns were classified following Vertucci's criteria.

Results: All incisors in this study had 1 root. Canines usually had a single root and much less often had 2 roots. Type I and III root canal configurations were found most often, while type V and II configurations were less frequent. Significant compatibility between the left and right side was observed in all evaluated variables. Incisors had the highest symmetry with regard to the number of roots (100%). Second canals were observed more often in males than females, but only the results in lateral incisors were significant.

Conclusions: This study provides supplemental information for dentists and should help them to better predict the morphology of mandibular anterior teeth in complicated cases in the Polish population. Symmetry was observed in roots and root canal morphology in all examined parameters.
