摘要：Legal Medicine has great importance in the process of human identification, especially when specialists in the field receive only the cephalic portion of the body for analysis.The aim of this study is to verify sexual dimorphism and age prediction through measurements in occipital bones of adult dry skulls.The authors studied a sample of 149 dry skulls, of which 90 were male and 59 were female.They belonged to individuals over 20 years of age and with a known sex and age with total security.The following measurements were taken: distance between condylar foramen (ifc); distance between the right condylar foramen and the basal (fcd-b); distance between the left condylar foramen and basal (fce-b), as well as a triangular area formed by these linear measurements (atz).All variables underwent an analysis of variance in order to test for the existence of sex effect, and their residual normality was evaluated by the asymmetry, kurtosis and Shapiro-Wilk test.According to the statistical analysis, there was a success rate of 69.6% for logistic regression.Basic statistics such as the mean and confidence interval were also verified using the t-test and the multiple linear regression method was used too for the prediction of age, noting that the model presented significant results in two variables.(p = 0.0105).The results allowed the elaboration of a statistical methodology for the diagnosis of gender and age in future observations.
