- Abstract
Sex assessment is an importante information when human remains are described. In this regard, skulls and madibles can offer important parameters. The objective of the study was to evaluate the accuracy of the mandibular angle on sex assessment in a Brazilian sample. Sixty six computed tomographies of mandibles from the Guarulhos' Forensic Anthropology Investigation Center were evaluated, and the goniac angle was measured using the VG Studio Max 2.1® program. The mandibles had known sex, but the observer didn't have access to this information until the end of the measurements. Logistic regression was used and the level of significance was of 5%. The investigation was approved by the Ethics Committee of the University of São Paulo's School of Dentistry (CEP-FOUSP). Thirty three male and 33 female mandibles were evaluated. The mean male goniac angle was 128.3 (± 1.46) and the female was 131.2 (± 1.19) (p=0.13). For male 60.61% of the measurements were correct, and among female mandibles, 48.48%. The values of the goniac angles were lower among male than female mandibles; also, no differences between the groups were found. More studies should be performed using different samples in order to improve the measurements' accuracy.
