“…But, in situations where the skeleton is not complete 4 or when the pelvis is not fully recovered, sex estimation can be achieved by performing a cranial analysis. As mentioned by Spradley and Jantz 4 (2011), the skull has a high correct classification of sex, of 90-91%.…”

“…In general, bone aspects such as prominences, crests and apophyses are more notable in men, while women have more delicate and less pronounced characteristics 14 . Walker (2008) 11 stated that the accuracy of sex determinations based on visual inspection depends on the osteologist's familiarity with the population being studied. And Franklin et al (2013) 15 mentioned that the forensic practitioner should access an osteological database for their specific geographic jurisdiction.…”

Forensic physical anthropometry allows the determination of animal species and estimates sex, ancestry, age and height. Aim: To analyze the effectiveness of a cranioscopic/ morphological evaluation for sex estimation with a sample of the Brazilian mixed-race population by conducting a qualitative visual assessment without prior knowledge of sex. Methods: This is a blind cross-sectional study that evaluated 30 cranial characteristics of 192 skulls with mandible, 108 male and 84 female individuals, aged 22 to 97 years, from the Osteological and Tomographic Biobank. The qualitative characteristics were classified and compared to the actual sex information of the Biobank database. The statistical analysis was used to calculate de Cohen’s kappa coefficient, total percentage of agreement, sensitivity and specificity of visual sex classification. Results: Of the 30 cranial variables analyzed, 15 presented moderate degree of agreement, achieving value of Kappa test between 0.41–0.60: Glabella (Gl), Angle and lines (At), Mental eminence (Em), Mandible size (Tm), Cranial base (Bc), Mouth depth (Pb), Nasal aperture (Anl), Supraorbital region (Rs), Orbits (Orb), Mastoid processes (Pm), Alveolar arches (Aa), Zygomatic arch (Az), Orbital edge (Bo), Supraorbital protuberances (Pts), and Supramastoid crests and rugosity (Crsm). The Facial physiognomy (Ff) presented substantial reliability (0.61-0.80) with 89.8% sensitivity for male sex and 70.2% specificity. Conclusions: Cranial morphological characteristics present sexual dimorphism; however, in this study only 15 variables showed moderate degree of agreement and can be used in sex estimation. Only one variable (Ff) 81.2% total agreement with substantial reliability. Quantitative methods can be associated for safe sex estimation.

Nas situações em que os corpos estão em avançado estado de putrefação, a análise dos arcos dentais é um importante método para identificação humana, pois os dentes apresentam características únicas para cada indivíduo. Nos dias atuais, a acessibilidade a smartphones com câmeras permitiu novos parâmetros na rotina de perícias odontolegais, visto a frequente utilização dos autorretratos (selfies) nas redes sociais. O presente estudo teve como objetivo relatar três casos de identificação humana realizados em que foi utilizado o método de comparação entre fotografias do sorriso em vida e registros post-mortem para o processo de identificação. Realizaram-se estudos antropológicos para traçar o perfil biológico por meio da estimativa de sexo, idade, ancestralidade e estatura. Em seguida, procedeu-se à análise morfológica visual e ao delineamento computadorizado da linha do sorriso de imagens ante mortem (AM) e post-mortem (PM). Em todos os casos, o confronto dos registros e materiais AM e PM apontaram coincidências e nenhuma divergência, trazendo uma identificação positiva. Desta forma, conclui-se que a fotografia do sorriso é uma grande aliada na identificação humana. Os relatos demonstraram um resultado promissor do uso de fotografias do sorriso; entretanto, por ser uma técnica recente e pela escassez de pesquisas na literatura, é essencial a produção de mais estudos científicos para a determinação precisa de sua aplicabilidade.
