The purpose of this research was to identify the presence of radicular grooves (SR) in the external root anatomy and its relationship with the Vertucci classification in mandibular first premolar of a Colombian subpopulation.
Images were analyzed using cone beam computed tomography (CBCT) in three planes (coronal, sagittal and axial), of 140 human mandibular first premolar, and the anatomical configuration of the root canals was determined according to the classification of Vertucci. Subsequently, the SRs of these pieces were recognized in the axial sections of the CBCT images.
It was established that typology I according to the Vertucci classification was the one with the highest frequency 72.14% (101/140), followed by type V in 19.28% (27/140). Similarly, the presence of root grooves (SR) corresponded to 30% (42/140).
With this study, a large percentage of anatomical variations in mandibular first premolar of a Colombian population was evidenced, this reinforces the need to know in detail the dental anatomy to establish more effective strategies and protocols and thus achieve a successful endodontic treatment at long term.
