Abstract The mandibular foramen (MF) marks the entry of the inferior alveolar nerve (IAN) into the mandibular canal and shows considerable anatomical variability, making its accurate localization clinically essential. Orthopantomogram (OPG) is a widely used panoramic imaging modality for identifying maxillofacial anatomical landmarks due to its accessibility and diagnostic efficiency. This retrospective study aimed to evaluate the anteroposterior and superoinferior position of the MF using digital OPGs in an Indian population. Quantitative measurements were obtained from anonymized digital OPG records and subjected to statistical analysis. The mean anteroposterior distance of the MF from the anterior border of the mandibular ramus was 15.96 ± 1.82 mm, with minimal right–left side variation. Conclusion: Digital OPG is a reliable and accurate modality for determining the location of the MF based on anteroposterior and superoinferior measurements. The findings are clinically relevant for improving the success of inferior alveolar nerve block anesthesia and for aiding preoperative planning in mandibular orthognathic surgeries and ramus osteotomies, thereby reducing procedural complications.
