OSTEOLOGICAL STUDY OF SEXUAL DIMORPHISM IN RAMUS WIDTH OF MANDIBLE
Journal Title: JOURNAL OF ANATOMICAL SCIENCES - Year 2017, Vol 25, Issue 2
Abstract
Introduction: The metric data of mandible are used to identify gender of an unknown individual in the field of anthropology and forensic science. Due to its hard density, mandible is commonly available in complete or fragment form and therefore it has a vital role in sex determination. Various metric traits like angle of mandible, gonial width, ramus length has been studied for gender variation. In addition to these, width of ramus need to be assessed for gender variation. Material & Methods: Total 60 dry human mandibles of both sexes were taken for the study. Mandible with any discrepancy and damage were excluded. Sliding caliper was used to measure maximum and minimum ramus width of mandibles. Results: Study showed that there was no significant difference between the mean minimum width of ramus of right side in male and female mandibles whereas significant difference was seen on left side for same variable of male and female. There was a significant difference between the mean maximum width of ramus of male and female mandibles of both right and left sides. Conclusion: Variations in width of ramus might be due to some functional difference of masticatory muscles in a race but this variation can be utilized in sex determination and designing implants.
