Análisis de la morfología de los conductos de primeros molares inferiores mediante cortes tomográficos, Innova, 2019-2020.

Abstract

Introduction: The success of an endodontic therapy depends on a correct disinfection of the root canals and a suitable obturation that allows a tight seal. However, there are many variables that can affect the success of the treatment during the disinfection and preparation of the canals: such as the inability to identify any variation in number and configuration in the internal anatomy of the root canals. Objective: To determine the prevalence of the mesio medial duct in the lower first molars, as well as its anatomical configuration, by tomographic analysis. Materials and methods: An investigation was carried out of an imageneological, observational cross-sectional type at the Innova radiological center. 212 tomographs were analyzed and the inclusion and exclusion criteria were applied. 70 tomographs were selected during the period from 2019 to 2020, of 95 lower first molars, consisting of 47 women and 23 men between 15 and 63 years of age. Results: Of the first 95 lower molars, 3 showed middlemesial canal, all configurations were mostly confluent, according to the Pomeranz classification. The most current configuration according to Vertucci in the mesial canal was 66.30% type II and in the distal canal 65.95% type I. In what corresponds to the total number of first molar canals, 61 molars (64.20%) showed 3 canals, 32 (33.68%) showed 4 canals, while 2 (1.07%) 5 canals. Conclusion: It was concluded that there was no high prevalence of the mesio medial duct, all of which were confluent according to Pomeranz. The most common duct configuration in the mesial canal was type II and type I in distal canal, according to Vertucci.
