To localize the mandibular foramen in dry mandibles of adult and old age groups of South Indian origin by estimating its average distance from different anatomical landmarks and to provide a specific and precise site for inferior alveolar nerve block. : A total of 51 mandibles were taken for the study and the distance between the mandibular foramen and the various anatomical landmarks were measured using a digital vernier caliper. Presence of accessory mandibular foramen was observed and recorded. Difference between the sides and the correlation between the gonial angle and various distances were carried out.:Distance of mandibular foramen from anterior border was 16.41±2.44 mm and 16.85±2.55 mm, from posterior border was 10.28±2.08 mm and 10.13±2.02 mm, from mandibular incisure 22.5±3.13mm and 21.9±3.08mm, from mandibular base 23.72±3.37 mm and 24.5±3.27 mm, from third molar 15.27±11.99 mm and 16.85±11.60 mm, from apex of retro molar trigone 18.28±3.02 mm and 19.79±3.18 mm on right and left side respectively. There was no significant difference between the measurements of right and left sides. The measurements had a negative association with gonial angle. Accessory foramina were found to be present in 21and 23 mandibles on right and left side respectively.:Precise localization of mandibular foramen is clinically very important to achieve effective inferior alveolar nerve block prior to dental surgeries in the lower jaw. The present study establishes the presence of bilateral symmetry in the position of mandibular foramen with respect to various anatomical landmarks and the utility of gonial angle in localizing the mandibular foramen.

“…The results of this study were also in agreement with those of other studies. [16][17][18][19][20] The distance between symphysis menti and mandibular foramen of both right side (79.08 ± 4.35 mm versus 74.67 ± 5.45 mm; p<0.001) and left side (78.98 ± 5.13 mm versus 73.71 ± 5.33 mm; p<0.001) were longer in male compared to female. But, the distance between symphysis menti and mandibular foramen of the right(77.23 ± 5.14 mm) and left side (76.77 ± 5.79 mm) did not differ statistically significant (p=0.677).…”

Introduction: An important aspect of medico legal and anthropological work is the identification of human skeletal remains. After death, bones often survive decay and provide evidence of a person's sex. As the strongest bone in the facial skeleton, the mandible often resists post-mortem damage and provides important information about sexual dimorphism. Objective: Assessing the morphometric changes in the dry human mandible to ascertain sex is the study's goal. Methods: From January to December 2017, a descriptive study took place at the Department of Anatomy, Sylhet MAG Osmani Medical College, Sylhet. By using a convenient sampling method 50 adults, dry, complete, undamaged human mandibles were selected. Results: A variety of measurements were made, recorded as Mean ± SD, and examined using SPSS Statistics 21's unpaired t-test. The results showed statistically significant differences between both genders in mandibular angle, mandibular ramus's length, and mandibular foramen. Conclusion: This research has shown that it is possible to determine the gender of the mandible by using different metrical parameters as an additional tool to establish a person's identity.

Background : The mandibular foramen (MF) is the anatomic landmark where the interior alveolar nerve enters the mandibular ramus, and the area of choice where anesthesia of this nerve is performed. The position of the MF can vary, and accurately establishing its location and topographic variations is of great importance for the successful anesthesia of the inferior alveolar nerve. Materials and Methods : We carried out two morphometric ex vivo studies concerning the topography of the MF, on dry human mandibles coming from dentate and completely edentulous human subjects of known age and gender and an in vivo morphometric study, through cone-beam computed tomography (CBCT) scans, concerning the topography of the MF in human subjects having Kennedy Class I mandibular edentulism. The morphological characteristics we investigated were: the distance between the MF and the anterior margin of the mandibular ramus (MF–AM distance), the distance between the MF and the posterior margin of the mandibular ramus (MF–PM distance), the distance between the MF and the inferior margin of the mandibular ramus (MF–IM distance), the distance between the MF and the temporal crest of the mandibular ramus (MF–TC distance), the distance between the MF and the superior margin of the mandibular ramus (MF–SM distance), and the vertical and transverse diameters of the MF. The results were statistically processed in Stata/MP13 software package using Student’s t -test and two-way analysis of variance (ANOVA). Results : Through direct morphometry on dentate dry human mandibles, the MF–AM and the MF–SM distances showed statistically significant differences for age, gender and for interactions, while the MF–PM and MF–IM distances showed statistically significant differences for age and for interactions. In the case of the MF–TC distance, the only significant difference observed was for the gender. No statistical significance was found for side, age, gender, and interactions in the cases of MF vertical and transverse diameters. Through direct morphometry on completely edentulous dry human mandibles, the MF–PM and MF–SM distances showed statistically significant differences for age, gender and for interactions, while the MF–AM, MF–IM, and MF–TC distances, as well as the MF vertical and transverse diameters showed statistically significant differences for age and for model (interactions). The results showed that MF is 2 mm closer to the anterior margin of the mandibular ramus after having lost teeth. Through imaging morphometry, the MF–PM distance and the vertical diameter of MF showed statistically significant differences for age, gender and for interactions, while the MF–AM, MF–IM, MF–SM and MF–TC distances, as well as the transverse diameter of MF showed statistically significant differences for age and for interactions. Comparing the results obtained by the three studies, we found no statistically significant diff...
