Background: The knowledge of root canal anatomy and of the anatomical relationship should be considered mandatory when planning surgical endodontics. The aim of the study was to investigate the anatomical features of mandibular premolars, evaluating their relationship with mental nerve.
Material And Methods: CBCT scans were evaluated recording the number of roots, root canal configuration and the relationship with mental nerve of 100 mandibular premolars.
Aim: The aim of the present study was to evaluate the number of roots and the anatomy of root canal systems of permanent mandibular premolars using images derived from cone-beam computed tomography (CBCT) scans.
Methods: Mandibular CBCT scans of a cohort of Caucasians (Italians) were evaluated using a dedicated software. The number of roots and the anatomy of root canal systems (following the classification by Vertucci) were recorded, and the prevalence of each type was calculated.
