SEX AND AGE ESTIMATION BY CRANIAL MEASUREMENTS

Abstract

Introduction: Forensic Dentistry has a great importance in the process of human identification, especially when the professional has only the cranium to analyze. The aim of this study is to verify the sex dimorphism and age estimation by the facial measurements. Materials and Methods: A sample of 150 dry skulls was studied, 80 male and 70 female, which belonged to individuals aged over 20 years old. The sex and age of the individuals were surely known. The skulls that have been studied belonged to people whose bones have not been claimed by their relatives in the determined time by the cemetery and were being sent for incineration. The following measurements have been done: frontal curve and distance between bregma and mastoid process. Results: According to the statistical analysis, there was success rate of 71.8% by logistic regression and 70% by the discriminant analysis. It was also verified the mean and confidence interval by t test and used the method of multiple linear regression to predict age, evidencing the model was not significant (p = 0.5390). Conclusion: The results enable the development of a statistical methodology to identify gender and age in future observations.
