“…It is suggested, regarding the small difference between men and women in those two measures (left and right sides), that this could be justified by the large intermingling existent in Brazil, which would have caused modifications in the characteristics that would be distinguishable among the different ethnicities, therefore allowing for less sexual differentiation. Such situation was also found by Steyn & Iscan [13], in which they verified that the bizygomatic measure was the most dimorphic among the 91 evaluated skeletons from the Pretoria and Witwatersand Collection.…”

Introduction: Sex estimates are generally based on the evaluation of qualitative and quantitative aspects of anatomic structures, however, the latter has better reproducibility and reliability. Objective: Aiming to evaluate the viscerocranium as a tool for sexual prediction and verify the possibility of creation of a logistic regression model for sexual prediction. Materials and Methods: 167 craniums - 100 male and 67 female between 22 and 85 years old from a Brazilian university´s Biobank - were evaluated. Results: It was observed that of the measures carried out were presented as sexually dimorphic, except for the measures of the right frontozygomatic point – right zygion; left frontozygomatic point – left zygion. Besides, it was possible to create a logistic regression model Sex = [logits/Sex = -24.5 + (0.20 * Nasion - Naso spine) + (0.18 * Right zygion - Naso spine)]. Conclusion: It was concluded that the measures of the viscerocranium present themselves as a factor of sexual dimorphism and the quantitative method developed was 81.4% accurate.

Annotation. Determining the characteristics of certain indicators within a certain population, the relationship between certain anatomical structures and parameters of the human body is one of the key tasks of clinical anthropology. Identifying the nature, strength and direction of the interdependencies of such indicators is a key element not only for understanding human nature but also for solving clinical, including dental problems today. The aim of the study was to establish in Ukrainian young men and young women with orthognathic occlusion the peculiarities of correlations of teleradiographic parameters of tooth location determined by Bjork, Jarabak and Sassouni methods with parameters of upper and lower jaws and tooth location. Teleradiography in the mode of cephalometric examination was performed for 49 young men and 76 young women with orthognathic occlusion. Cephalometric analysis was performed using OnyxCeph³™ software, 3DPro version, Image Instruments GmbH, Germany (software license URSQ-1799). Correlation assessment was performed in the license package “Statistica 6.0” using the non-parametric Spearman method. In young men and young women, the features of multiple correlations of teleradiographic parameters of the upper and lower jaws with the parameters of the location of the teeth determined by the methods of CFT-Bjork, Roth-Jarabak and Sassouni. As a result of quantitative analysis of significant correlations between teleradiographic parameters of the upper and lower jaws with the parameters of the location of the teeth found: CFT-Bjork in young men 46.9 %, of which 5.4 % straight strong, 18.5 % straight medium and 2.3 % straight weak and 2.3 % reversible strong, 16.2 % reversible medium strength and 2.3 % reverse weak, and young women – 38.5 %, of which, 2.3 % direct strong, 15.4 % direct medium strength and 6.2 % direct weak and 0.8 % reverse strong, 7.7 % reverse medium strength and 6.2 % of reversible weak; according to the Roth-Jarabak method, 36.2 % of young men, 6.6 % of direct strong, 11.8 % of direct medium strength and 2.6 % of direct weak and 2.6 % of reverse strong, 11.8 % of reverse of medium strength and 0.7 % of reverse weak, and young women – 44.7 %, of which, 3.9 % direct strong, 15.1 % direct medium strength and 7.2 % direct weak and 0.7 % reverse strong, 8.6 % reverse medium strength and 9.2 % reverse weak; according to the Sassouni method, 42.8 % of young men have all medium-strength, and 42.8 % of young women have, of which 35.7 % have medium-strength and 7.1 % have weak straight. Manifestations of sexual dimorphism of the received correlations are established only between the indicators defined by CFT-Bjork and Roth-Jarabak methods.

“…Measurements of five skulls with noted ACD were analyzed to quantify osteological traits, assess intragroup relationships (variance of structures), and determine type of intentional cephalic modeling (Brewster et al, 2014; Dudzik & Kolatorowicz, 2016; Zaki et al, 2012). Thirteen landmarks homologous to traditional craniometric points that cover the main components of the skull (facial region, neurocranium, and base) were used (Langley et al, 2016; Romano‐Pacheco, 1965; Romano‐Pacheco, 2005; Serrano‐Sánchez et al, 2021).…”

ObjectivesDetermine the geographic place of origin and maternal lineage of prehistoric human skeletal remains discovered in Puyil Cave, Tabasco State, Mexico, located in a region currently populated by Olmec, Zoque and Maya populations.Materials and MethodsAll specimens were radiocarbon (14C) dated (beta analytic), had dental modifications classified, and had an analysis of 13 homologous reference points conducted to evaluate artificial cranial deformation (ACD). Following DNA purification, hypervariable region I (HVR‐1) of the mitogenome was amplified and Sanger sequenced. Finally, Next Generation Sequencing (NGS) was performed for total DNA. Mitochondrial DNA (mtDNA) variants and haplogroups were determined using BioEdit 7.2 and IGV software and confirmed with MITOMASTER and WebHome softwares.ResultsRadiocarbon dating (14C) demonstrated that the inhabitants of Puyil Cave lived during the Archaic and Classic Periods and displayed tabular oblique and tabular mimetic ACD. These pre‐Hispanic remains exhibited five mtDNA lineages: A, A2, C1, C1c and D4. Network analysis revealed a close genetic affinity between pre‐Hispanic Puyil Cave inhabitants and contemporary Maya subpopulations from Mexico and Guatemala, as well as individuals from Bolivia, Brazil, the Dominican Republic, and China.ConclusionsOur results elucidate the dispersal of pre‐Hispanic Olmec and Maya ancestors and suggest that ACD practices are closely related to Olmec and Maya practices. Additionally, we conclude that ACD has likely been practiced in the region since the Middle‐Archaic Period.
