ABSTRACT

Introduction: the second and third lower molars are the last teeth to erupt, so they may have a close relationship with the lower dental canal. The distance between these structures varies according to age, sex or hemiarch; however, being very close presents a greater risk of nerve damage. Objective: to establish the relationship of the apices of the second and third lower molars with respect to the cortex of the lower dental canal. Material and methods: observational, analytical and cross-sectional study, a sample of 356 radiographs was used; with the AutoCAD 2023 software and the Cartes and Fauzi method, the proximity relationship was established. The data was recorded in an Excel 2019 matrix and was analyzed in the SPSS v. 26.0 program, descriptive statistics for absolute and relative frequencies, for the association between variables with the Pearson and χ² test (p < 0.05). Results: the lower second molars are the dental organs that present a proximity relationship that decreases as the age of the patient is greater for the samples on the cortex; and it is greater when it is below the cortex. Conclusion: the distance that exists between the cortex of the lower dental canal with the apices of the second lower molars increases as the age of the patient increases.
