Mandibular Ramus: An Indicator for Gender Determination - A Digital Radiographic Study
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2018, Vol 6, Issue 7
Abstract
Aims and Objectives: The objectives of this study were as follows: (1) To measure, compare, and evaluate the various measurements of mandibular ramus as observed on orthopantomographs and (2) to assess the usefulness of mandibular ramus as an aid in gender determination. Materials and Methods: A retrospective study was conducted on 50 males and 50 females using standard digital panoramic radiographs with age ranging from 18 to 58 years. The following five mandibular linear measurements were performed in cm such as maximum ramus breadth, minimum ramus breadth, condylar ramus height, projective ramus height, and coronoid ramus height. The obtained data were analyzed with the software SPSS (version 20.0) and Microsoft Excelled (version 5.00) for statistical analysis using discriminant methods. Results: Mean measurements descriptive statistic shows that mean values were significantly higher in males compared to females (P < 0.05). Fisher-statistic values indicated that highest sexual dimorphism was seen with condylar ramus height and least with minimum ramus breadth, maximum ramus breadth, condylar height, condylar ramus height, coronoid height, and minimum ramus breadth. Sex was accurately determined in 44 cases of 50 male mandibular measurements with prediction accuracy rate of 88% and sex was accurately determined in 46 cases of 50 female mandibular measurements with an accuracy rate of 92%. Conclusion: The result of the present study proved that the mandibular ramus plays a major role in gender determination due to its unique high sexual dimorphism and also possesses resistance to damage and disintegration processes. Hence, we conclude that the use of mandibular ramus is recommended as an aid for sex determination in forensic science.
