Sex Determination of Human Mandible in Population of Bihar by Using Metrical Parameters
Journal Title: International Journal of Medical Research Professionals - Year 2018, Vol 4, Issue 6
Abstract
Background: The sex determination from bones are important part of study in forensic medicine as many interpretations and analysis depends upon it. In case of mass disasters like earthquake, explosions, warfare, floods, aircraft crashes, when only the fragmented bones and it’s part are found, sex determination becomes difficult and it depends largely on the available parts of skeleton. Mandible may play a significant role in sex determination, because it is most durable facial bone that retains its shape better than others bones. But, still no data are available on different metric parameters of human mandible for determination of sex in Bihar region hence the necessity of the present study arose. Materials and Methods: The present study is a cross sectional study which has been carried out on 156 dried fully ossified dentulous adult human mandibles (male: 90 and female:66). The age of the bones used in the study was not predetermined. The bigonial breadth, bicondylar breath, mandibular length and mandibular index was measured with the help of digital vernier caliper and mandibulometer. The software Graph Pad Prism version 4.03 was used for statistical analysis of data. The results were analysed by unpaired t-test. Results: In our study we found that mean value of the bigonial breadth, bicondylar breadth, mandibular length and mandibular index in male were 90.63 ± 8.16, 108 ± 9.06, 104.43 ± 12.78 and 96.59 ± 12.68 respectively and in female 90.12 ± 8.77, 108.35 ± 8.44, 101.78 ± 11.05 and 94.24 ± 10.19 respectively. Conclusion: Identification of gender from the available skeletal remains is of great anthropological and medico legal significance. The application of the metrical parameters like bigonial breadth, bicondylar breadth and mandibular length along with morphological features may be an useful tool for mandible. More studies involving different group of population with larger sample size may be helpful in gender determination using metric parameters or morphology among population of Bihar.
