Resumen

Introduction: Mandibular third molars are frequently impacted, motivating its surgical removal, can injure the inferior dental nerve. Methods: It was a basic, non-experimental, correlational and cross-sectional research. It had a population of 1422 tomographies and after verifying the inclusion criteria, a sample of 293 tomographies was taken, obtaining 475 third molars to carry out the study. Used three-dimensional imaging software program CS. A pilot test was performed in order to verify the degree of concordance using the Kappa statistical verifi-cation, giving a rate of 0.88. Results: It was found that 41.7% of the molars had contact with the mandibular canal and were located inferiorly (48.2%). Conclusions: The results of the present study show that there is a statistically significant relationship between the apex contact of the third molar and the location of the mandibular canal.
