Metric analysis of the patella for sex estimation in a Portuguese sample

The biological profile estimation is the first step toward positive identification. However, it is not always possible to access a complete and well-preserved skeleton due to postmortem damage and taphonomic changes. As such, there is a need to develop new alternatives to analyze different bones of the human skeleton. The present study aims to analyze the patellar osteometry, with attention to its degree of sex...

Evaluation of data collection bias of third molar stages of mineralisation for ...

Age assessment of the living is a fundamental procedure in the process of human identification, in order to guarantee fair treatment of individuals, which has ethical, civil, legal, and medical repercussions. The careful selection of the appropriate methods requires evaluation of several parameters: accuracy, precision of the method, as well as its reproducibility. The approach proposed by Mincer et al. adapted...

Automated age‐at‐death estimation by cementochronology: Essential application o...

It has been repeatedly acknowledged that age-at-death estimation based on dentalcementum represents a partial and time-consuming method that hinders adoptionof this histological approach. User-friendly micrograph analysis represents a grow-ing request of cementochronology. This article evaluates the feasibility of using amodule to accurately quantify cementum deposits and compares the module's per-formance to t...

Recent Advances in Forensic Anthropological Methods and Research

Adult skeletal age-at-death estimation through deep random neural networks: a n...

Age-at-death assessment is a crucial step in the identification process of skeletal human remains. Nonetheless, in adult individuals this task is particularly difficult to achieve with reasonable accuracy due to high variability in the senescence processes. To improve the accuracy of age-at-estimation, in this work we propose a new method based on a multifactorial macroscopic analysis and deep random neural net...

Challenges and (Un)Certainties for DNAm Age Estimation in Future

Age estimation is a paramount issue in criminal, anthropological, and forensic research. Because of this, several areas of research have focused on the establishment of new approaches for age prediction, including bimolecular and anthropological methods. In recent years, DNA methylation (DNAm) has arisen as one of the hottest topics in the field. Many studies have developed age- prediction models (APMs) based o...

The unidentified skeletal collection of Capuchos Cemetery (Santarém) housed at ...

The aim of this article is to present to the scientific and academic community a new osteological collection housed at the Department of Life Sciences from the University of Coimbra (Portugal), the Unidentified Skeletal Collection of the Capuchos Cemetery. The skeletons were collected from the same cemetery as those of the 21st Century Identified Skeletal Collection, however their identity is unknown. The colle...

Technical Note: The Forensic Anthropology Society of Europe (FASE) Map of Ident...

Identified (documented) osteological collections represent an important resource in the development of forensic anthropology standards and methods as well as a precious tool for learning and training of practitioners. Even though the number of papers presenting identified collections worldwide increases, many of the collections have still not been divulged to the scientific community in sufficient detail to asc...

Aging the death: the importance of having better methods for age at death estim...

A Blood–bone–tooth model for age prediction in forensic contexts

The development of age prediction models (APMs) focusing on DNA methylation (DNAm) levels has revolutionized the forensic age estimation field. Meanwhile, the predictive ability of multi-tissue models with similar high accuracy needs to be explored. This study aimed to build multi-tissue APMs combining blood, bones and tooth samples, herein named blood–bone–tooth-APM (BBT-APM), using two different methodologies...
