Evaluación de la Morfología de Conductos Radiculares en Molares Superiores de una Población Colombiana. Estudio mediante CBCT

Abstract

Introduction: the most used diagnostic tool in endodontics is the periapical radiography because it is a fast, simple and easy to interpret technique, which has been considered a very good option when evaluating the anatomy of the root canal system. Nowadays cone beam computed tomography (CBCT) is useful to provide precise anatomical details in three dimensions, in diagnosis and planning before endodontic therapy. Objective: to describe the internal root anatomy of maxillary first and second molars by means of CBCT in a radiological center in Bucaramanga, Colombia. Method: descriptive observational cross-sectional study, through CBCT observation of the internal and external anatomy of the upper first and second molars, data collection through the variables: presence of MV2, Vertucci configuration, number of roots, presence of fusion, fused roots and level of the fusion. Results: The presence of two canals in the MV root was 34.59% in first molars with a Vertucci configuration type I in 65.94%, type II in 20.5%, followed by type IV with 11, 3% and 16.6% for second molars, with a Vertucci configuration type I in 84.8%, type II in 10.7% and type IV in 3.92%. According to age groups, those aged 41-52 years presented a higher frequency of upper first molar fusion with 40% and upper second molar with 34.78%, the roots with more fusion for this same group, the DV-P in 64.28 % in the first molar and the MV-DV-P roots in 47.5% for the second molar, and in the level of fusion for the same age group it was apical third with 35.71% in first molars and 77. 5% for second molars. Conclusion: a higher prevalence of MV2 was found in upper first molars versus upper second molars, greater root fusion in second molars with the fusion of the MV-DV-P roots and the level of fusion up to the apical third.
