Evaluation of the correlation between Cephalometric parameters and sex prediction in West Uttar Pradesh: A Cross-Sectionail study

Abstract

ABSTRACTAs the consolidation of dimorphic characteristics concludes the sex of the individual, osteological examination is a very reliable tool for determining the sex of the individual. This research was carried out using lateral cephalograms and an index was formed, which could be considered as a reliable sex determinant in forensic applications. Materials and Methods: This study was performed on samples of west Utiar Pradesh population. Fitiy individuals, whose age ranged between 25 and 40 years, were taken (25 male subjects and 25 female subjects). All conven????onal hard tissue cephalometric variables were compared, subjected to statistical analysis and tested for significance. Results: Out of a total of 72 variables tested, only six variables showed statistical significance. These six variables were then subjected to discriminant function analysis to evaluate the effectiveness of each variable in predicting the sex of an individual. Individually, the Y-axis showed the highest sex determining dependability of 76% followed by a facial angle showing 74% dependability. On the other hand, lower facial height angle (68%), mandibular plane angle (68%), Pog to N perpendicular (66%), and mandibular length Go-Gn (60%) showed lowest consistency. With regard to individual sex, the Yaxis shown the highest reliability at 76%, followed by a facial angle at 74%. Conclusion: From this study, it is evident that cephalometric parameters are reliable in determining the sex of an individual. All the statistically significant data showed high and acceptable percentage of reliability. This proves that the chosen variables can be used for West Utiar Pradesh population to determine the sex of individuals of interest.
