Abstract: This study assessed the mandibular foramen (MF) position variability in dentate and edentate Brazilian mandibles. Eighty dentate and 79 edentate mandibles of unknown sex were measured bilaterally using a digital caliper (0.1-mm precision). Horizontal linear measurements (HM) were done from the MF to the anterior border of the mandibular ramus (MF-A) and from the MF to the posterior border of the mandibular ramus (MF-B). Vertical linear measurements (VM) were done from the MF to the most inferior point of the mandibular notch (MF-C) and from the MF to the inferior border of the mandibular ramus (MF-D). Data were analyzed by two-way ANOVA (alpha = 5%). The HM means and standard deviations (+/-SD) for MF-A were, edentate right (ER): 17.5 (+/-3.2) mm, edentate left (EL): 17.4 (+/-3.4) mm, dentate right (DR): 19.2 (+/-3.6) mm, and dentate left (DL): 18.8 (+/-3.8) mm. The means (+/-SD) for the MF-B measurements were, respectively, ER: 12.8 (+/-2.4) mm, EL: 12.9 (+/-2.3) mm, DR: 14.2 (+/-2.4) mm, and DL: 13.9 (+/-2.6) mm. The VM values for the MF-C measurements were, ER: 23.4 (+/-3.8) mm, EL: 22.9 (+/-3.7) mm, DR: 23.6 (+/-3.1) mm, and DL: 23.1 (+/-3) mm, and for the MF-D measurements, ER: 26.4 (+/-4.2) mm, EL: 26.4 (+/-4) mm, DR 28.3 (+/-3.9) mm, and DL 28 (+/-3.8) mm. Side had no influence (p>0.05) on any edentate or dentate mandible measurement. Dentate mandible measurements showed statistically significant differences compared to the edentate mandibles, except for MF-C. The mandibular foramen position changes with loss of teeth and this variability may be responsible for occasional failure of inferior alveolar nerve block.
