Location of Mandibular Foramen in Correlation with the Gonial Angle in Indian Population: A Morphometric Study for Surgical Practices.

ABSTRACT

Background: The mandibular foramen, is the emerging point of the neurovascular bundle which makes it fundamental for performing anaesthetic techniques for desensitization of the mandible in oral surgery interventions. The knowledge of position of mandibular foramen is neccessary while anaesthetizing palate during periodontal procedures, tooth extractions and maxillofacial surgeries. Objective: The present study was carried out to identify the position and location of mandibular foramen in relation to the angle of mandible (gonial angle) in adult human mandibles of Indian origin . Materials and Methods: The study was conducted on 300 adult human dry skulls of Indian Population. Angle of mandible, Distance of mandibular foramen from angle of mandible and Angle of mandibular foramen with the base of mandible were measured. Measurements were done with Steel measuring tape and Mylometer. The data was Statistically analysed. Results and Conclusion: The Mean value of the angle of mandible (Gonial Angle) was 121.870 ± 6.220. The Mean value of the distance of mandibular foramen from angle of mandible was 22.78± 4.05 mm. The angle of mandibular foramen was Mean ± standard deviation of 82.240± 6.870. The morphometric correlation of the parameters analyzed in the mandibles showed a statistically significant Pearson correlation. Regression line was also derived.
