Morphometric Study of Dry Adult Human Mandible Using Minimum Ramus Breadth and Mandibular Angle in Mahakaushal Region

ABSTRACT

Proper analysis of human skeletal remains is very essential for medico legal and anthropological work. The mandible is the largest and the strongest bone of face. Mandible retains its shape better than other bones, so, it plays an important role for forensic osteology and anthropological works, hence, aim of present study to measure and compare the measurement of mandibular ramus and to assess the utility of mandibular ramus as aid in gender determination. 52 dry and adult human mandibles of known sex (29 male and 23 female) were used in this study. Measurement of the ramus and angle of the mandible were measured by sliding Vernier caliper and with the help of protector and the result was statistically analyzed using IBM SPSS software. In results it is found that angle of mandible in 29 male & 23 female mandibles of right side, mean & SD is 122.24 ± 6.71 & 124.61 ± 5.33 respectively and "P" value is 0.1734. Similarly in case of left side mean & SD is 121.59 ± 6.65 & 124.17 ± 5.87 respectively and "P" value is 0.1489. While measuring minimus ramus breadth it is noticed that mean & SD for right side in male and female are 31.44 ± 2.68 & 29.22 ± 3.040 respectively and the "P" value is 0.0073, on the other that, mean & SD for left side in male and female are 31.56 ± 2.47 & 29.31 ± 3.53 respectively and the "P" value is 0.0095Measurement of mandibular ramus may be used to differentiate between male and female bones and to determine the position of mandibular foramen and canal by maxillofacial and plastic surgeons to preserve the neurovascular bundles of mandible during surgeries.
