Relación entre raíces de terceros molares inferiores mesio - angular y conducto dentario inferior mediante tomografías Cone-Beam.

Abstract

Introduction: The lesion of the inferior dental nerve during the extractions of mandibular third molars can be produced by presenting a distance of less than 0.7mm, for this reason it is necessary to know the post-surgical problems that can be caused by hurting the anatomical structure. Objective: The purpose of the study was to determine the average distance between the inferior alveolar nerve NAI and the relationship with the roots of the third molars in mesioangular position before surgery. Methods: An observational and descriptive study was conducted where 60 TCCB digital beam tomography of both sexes were analyzed, performing sagittal cuts to observe the relationship of the NAI cortex with the root of the third mole. Results: The anatomy of the inferior dental canal that was presented in the study, is a single conduit that runs through the entire mandibular body in 100%, the average distance between the roots of the lower third molars with the cortical of the dental canal is from 2.2 to 3.3 mm with the Demirjian H classification and the D category is 0.3 mm. Conclusions: The results obtained in the study of patients between 18 to 19 years have a shorter distance in relation to the IMR and NAI with a range of 0.2 to 0.3 mm, I feel the female sex that I have an intimate contact between the roots with the cortical of the dental canal lower.
