Prevalencia configuración Vertucci en dientes anteroinferiores evaluados mediante CBCT en una población Colombiana

Abstract

Introduction: Permanent anteroinferior teeth have been considered as uniradicular teeth with a single canal from the pulp chamber to the apical foramen. One of the main causes that lead to failure in the endodontic procedure of anteroinferior teeth is the lack of knowledge about the anatomy of the root canal system (RCS) and its variations. Objective: To determine the prevalence, according to the Vertucci configuration, of the anatomy of the root canal system in permanent anteroinferior teeth evaluated by CBCT in a Colombian population. Materials and methods: According to the established inclusion criteria 677 anteroinferior teeth were selected as part of the sample, CBCT computerized tomography was used as a diagnostic aid to observe the Vertucci configuration from a sagittal view, 4 qualitative variables were evaluated: Vertucci classification, sex, type of tooth, number of canals and Chi2 and Fisher's exact statistical tests were carried out. Results: 140 topographies were selected, of which 80 (56%) corresponded to women being the majority of the population. According to the Vertucci configuration with the tooth, type I was determined as the most frequent classification with 53 (81.7%) in anteroinferior teeth, with type III in second place with 88 (13%). Conclusions: According to the topographies it was possible to establish the prevalence of the Vertucci configuration, whose classification was as follows: the right lower canine with 19.7%(109) , for type II the left lower canine 30%, type IV the left lateral incisor 25.0%, type V central and lateral incisors 20%, type VI 66.7%, type VII 57.1%.
