Introduction: The knowledge and morphometric analysis of the mandibular foramen (MF) and its relation with depression points of the mandible, anterior, posterior, inferior and superior borders, using the angular notch as a reference point and also the pogonion point is of great importance, since the mandibular foramen is used as a reference point for dental and surgical procedures such as prognathism and retrognathism. Objective: To analyze the relationships between the mandibular foramen and mandible anatomical points. Materials and methods: 60 dry jaws of cadavers were used in anatomical laboratories in Paraíba, Brazil. The analyzed variables were measured using a digital caliper. The Kolmogorov Smirnoff test was applied to analyze the normality of the data and then the means of the variables were compared through the t test. Results: For most variables there was variation between the sexes and sides, except for the width of the mandibular foramen, presenting difference between the sides of the same sex and there was no variation at the point of major depression. Conclusion: The findings of this study reveal differences in the location of MF between men and women, which differs from most studies. These findings provide useful information for surgical applicability, anesthetic blocking procedures, and reconstructive.
Key words: Jaw, mandibular foramen, morphometry, prognathism, retrognathism
