GONIAL ANGLE IN SEX DETERMINATION USING ORTHOPANTOMOGRAM (OPG) AN SHORT STUDY

Background: Forensic Anthropology has a crucial role in sex determination from human remains. Human skeleton such as cranium, pelvis and mandible. Several Anthropometric tools are there in determination of sex i.e. Shape of mandible, mental Foramen, gonial angle. Gonial angle has an excellent tool for sex determination. Gonial angle values may be changed due to bone density and masticatory forces. Aim of the study is to examine sex determination method using gonial angle. Materials and methods: A total of 50 radiographs (25 males and 25 females) were taken as per the study. This study was divided into two sections: male and female, between the age group 51 to 60 years. The gonial angle, which is formed by 2 lines: (1) between the most posterior point of the mandibular condyle and the gonion and (2) between the most inferior point of the mandibular symphysis- sis and gonion, was measured on computed tomography scans. Statistical analysis: The data were analysed by using SPSS software. The probability value p< 0.05 is considered as significant and the value p>0.05 was considered as not significant. Results: Tables and graphs show the sample size, mean and standard deviation of both males and females. In present research, a statistically significant correlation between dental maturity was confirmed. Results show Females were frequently observed to experience each stage of dental maturation earlier. Conclusion: The study concludes that the determination of sex using gonial angle measurement. This study demonstrates that categorising the sample into age groups makes the data more valuable for examining the differences related sex determination.
