Morphometric Study of Mandibular Foramina in Denatate and Edentulous Human Mandible in Gujarat Region

Abstract

Introduction: Precise knowledge of the location of reference points in the oral and maxillofacial area provides important data in local anesthesia and in maxillofacial operations. The important maxillofacial anatomical entities are neurovascular bundles passing through different foramina. The mandibular foramen is an opening on the medial aspect of the vertical ramus of the mandible approximately midway between the mandibular and gonial notches. Methodology: The material for the present study consists of 140 adult Mandible of unknown sex. These were collected from Govt. Medical college-Bhavnagar, P.D.U. Medical College, Rajkot and K.J.Mehta Dental College, Amargadh, Bhavnagar. Materials used are Vernier calipers of 0.02mm accuracy, Digital camera and Pencil. The data were statistically analyzed. Result: Site of mandibular foramina form posterior wall, inferior wall of mandibualar ramus and from mandibular notch(superior) on both the side in dentate and edentulous mandibles are significant statistically. The distance of mandibular foramen from anterior wall of mandibular ramus is not statistically significant on the left side. Conclusion: The knowledge of the distances from surgically encountered anatomical landmarks in the present study provide valuable information to dental surgeons that will facilitate effective localization of the neurovascular bundle passing through mental foramen thus avoiding complications from local anesthetic, surgical and other invasive procedures.
