Sex Determination from the Mandible of the Northeastern Thai Population: compared between Conventional and Radiographic Measurements
Keywords:
mandible, sex determination, radiographic imagesAbstract
Background and Objective: Forensic anthropologists can determine the gender of an individual from skeletal remains by using the mandible as an alternative method of identifying the skeleton's sex. The mandible is quite durable and not easily deteriorate, making it a reliable tool for gender and age determination.
Methods: Dried mandibles were selected for analysis. A manual conventional measurement was used to compare the characteristics of the mandible in the Northeastern population of Thailand distinguishing between males and females. Furthermore, the researchers compared the ability of computed tomography (CT) images to determine sex with conventional manual measurements. A total of 100 dry mandibles were used for this study, with 50 belonging to males and 50 to females. Ten variables were measured by using conventional method and there were 100 CT scan images analyzed in relation to four variables.
Result: The mean values of mandibular measurements were greater in males, when compared to females. According to dried bone analysis, the equation for sex determination was the most accurate at approximately 76.1%, and radiographic image was the highest accuracy of approximately 70.0%.
Conclusion: The results of this study showed that when it comes to be determined for the sex of individuals using the mandible, both methods are interchangeable because a similar level of accuracy and the mean values of measurements can be found in two methods.
