“…The mandible is one of the most resistant bones with high preservation rates in various environments. Although sex estimation methods based on the cranium are currently increasing in the Balkan Peninsula [11][12][13] the published studies on the mandible are restricted to archaeological populations [14], thus, without any forensic value.…”

The current study aims to test the value of mandibular size in sex estimation of a contemporary Greek population. The produced standards are expected to enhance identification of heavily decomposed remains in contemporary forensic settings. Data from 70 mandibles from a contemporary Greek collection have been analysed using discriminant function analysis. We selected individuals of less than 66 years old (mean age for men= 55.3 +/-8.8, for women= 50.9 +/-15.8) in order to avoid biases in the measurements due to alveolar absorbsion. A total of 5 measurements (chin height, bicondylar breadth, bigonial breadth, bimental breadth and minimum ramus height) were taken using traditional osteometric techniques. Data were analysed with SPSS 17. All variables were found to differ significantly between the sexes (p<0.05) with the exception of bimental breadth. Bigonial breadth was the most predictive variable which however did not exceed 71% of accuracy. The combination of bicondylar and bigonial breadth increased classification accuracy up to 80%. The results confirm the existence of sexual dimorphism in the Greek mandible, however the preliminary findings must be tested in a larger sample. Posterior probabilities are calculated in order to facilitate the decision-making of the forensic professional in post-Daubert forensic reality.

“…In present study this index showed a sexual difference without temporal variation (contemporary vs subrecent). Gabel [46] [73] and Romanian (M/F:57.78/57.16) [72]. It is also observed that the values may not always be greater in males.…”

Objectives: Ancestry and sex estimation using craniometric indices is an important aspect of skeletal identification process, as it limits the number of antemortem records used to compare with a postmortem profile and establish a positive identification. These indices are also affected by secular or temporal changes. So the aim of the study to explore the usefulness of indices for sex and ancestry estimation in North Indian population and effect of secular changes on these indices. Materials and methods:In present study two temporally different skull samples of the North Indian population have been taken and eighteen craniometric indices were calculated on the basis of 17 craniofacial measurements for both sexes to examine the temporal changes and their use in ancestry and sexual differenciation. Contemporary sample comprised of 158 skulls (110 male; 48 females) and subrecent 325 skulls (206 males and 119 females) with an age range of 20-68 years.Results: Craniofacial measurements showed significantly higher values in contemporary males and females. In males highly significant secular/temporal changes were observed in orbital index and transverse frontal index and to a lesser extent in foraman magnum and gnathic index. In females, highly significant differences were observed in cranial, vertical, auriculo vertical and longitudinal craniofacial index.Discussion: There is a lot of variability in Indian and non Indian populations so these indices can be used for ancestry estimation but not for sex discrimination due to poor classification rate. Moreover, the causes of these temporal variations with other issues have also been discussed.

“…The study established a sex determination accuracy based on these 2 variables of 80% for men and 69.2% for women, concluding that the measurements are significantly higher in men rather than women [55]. Rossi [56], Marinescu [57] and Nitek [58] reached the same conclusions.…”

Sex estimation remains one of the most important steps in a forensic anthropology context, especially when dealing with deteriorated or fragmented skeletal remains. In this respect, the need for the permanent actualisation of study database, as well of the skeletal remains is obvious. Therefore, besides classical skeletal collections an important amount of data can be obtained from computed imaging of the skeletal system, namely CT scans. The CT scans have the advantage of being virtually unlimited in number, not having any interference with secular trends, individuals being of known age and sex as well as increase in accessibility and applicability of data, for subsequent statistical and complex analysis (for instance, geometric morphometric). In the following review, we have gathered and compared some of the most significant studies in the field of physical and forensic anthropology focusing on sexual dimorphism on the skull, both on skeletal collections and CT scans. The results of the studies were similar in terms of sexing accuracy, thus allowing us to conclude that using CT scans in forensic anthropology is a viable and sometimes better option than skeletal collections, in term of data acquisition.
