“…Most of studies carried out on Egyptian population focused on anatomical variations of mandibular canal and mental foramen, thus to compensate for this shortage in previous studies we aimed to assess position of mandibular foramen using CBCT in Egyptian population. (13)(14)(15) This study evaluated the position of mandibular foramen in Egyptian population using CBCT. It is the most recent imaging technique in the maxillofacial imaging.…”

Aim: The present study designed to determine variations in mandibular foramen using CBCT in Egyptian population. Subjects and Method: 300 CBCT images were grouped according to sex, and symmetry between right and left sides into two groups. Group I: males& female and group II: right & left sides. Panoramic images were reconstructed from CBCT scans and evaluated using Blue sky software. The exact location of mandibular foramen at the two sides of the mandible was determined in relation to anterior border & posterior border of ramus, mandibular base, and mandibular notch. The recorded data will be collected, tabulated and statistically analyzed by SPSS (Statistical Package for Social Sciences). Results: This study showed bilateral asymmetry between right and left sides, no significant difference between 2 sides of the mandible. There was high significant difference in the distance from MF to mandibular base between males and females. No significant difference in other parameters relative to vertical and horizontal dimensions of mandibular ramus. Conclusions: All parameters related to the position of mandibular foramen in vertical and horizontal dimensions of mandibular ramus (MF-MB), (MF-MN), (PB-MF), and (AB-MF) were symmetrical in the right and left sides. The distance from mandibular foramen to mandibular base (MF-MB) was greater in males than females.

“…Israr et al studied the position of the mandibular foramen in North Indian population. 8 In their study they found that the mandibular foramen was situated at a mean distance of 16.06±1.99 mm from the anterior border and 12.02±1.99 mm from the posterior border respectively. 93 edentulous mandibles of Indian origin were studied by Thangavelu et al in 2011 according to them the mandibular foramen was located at a mean distance of 18.9±2.14 mm on right side and 18.88±2.34 mm on the left side from the anterior border of ramus of the mandible.…”

Background: This study was done to determine the precise location of the mandibular foramen so as to lower down the percentage of the failure of the attainment of the anaesthesia of the inferior alveolar nerve during dental procedures. Methods: In this cross sectional study a total of 50 dry human mandibles were examined. The measurements were taken from the anterior border of the ramus (coronoid notch) to the midportion of the MF (mandibular foramen) and from the midportion of the mandibular foramen to other landmarks such as posterior border of ramus, from inferior limit of MF to inferior border of ramus and the midpoint on symphysis menti. Results: The comparison of data was done using student’s t-test. The mandibular foramen was positioned at a mean distance of 18.26 mm (with a standard deviation of 1.77) from the anterior border of the ramus. The mean distance from posterior border of the ramus to the mid point of mandibular foramen was 13.5 mm with a SD of 2.16. Conclusions: The present study gives a fair knowledge of the position of mandibular foramen and provides information for successful local anesthesia of inferior nerve block to maxillofacial surgeons, ENT surgeons and onco-surgeons.

“…As shown in a recent literature review [ 3 ], Khan & Ansari (2016) [ 23 ] have mentioned that the absence of specific bone landmarks, alongside variations in height and width of the mandibular ramus are causes of failure of the inferior alveolar nerve anesthesia.…”

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...
