Forensic International Dental Database (FIDBv2) for adult age-at-death estimation in multiple forensic contexts: Strengthening the operationalization of the Lamendin criteria in a global scope model.

The aim of this study is to validate the FIDBv2 online procedure for adult age-at-death estimation using root dentine translucency (RDT) and periodontal retraction (PR) of single-rooted teeth in a worldwide sample. The sample includes 4810 teeth of 2559 individuals from 16 countries of America, Europe and Asia. Bias and inaccuracy between documented (DA) and estimated ages (EA) were calculated.

Radiographic morphology of canines tested for sexual dimorphism via convolutional-neural-network-based artificial intelligence.

The permanent left mandibular canines have been used for sexual dimorphism when human identification is necessary. Controversy remains whether the morphology of these teeth is actually useful to distinguish males and females. This study aimed to assess the sexual dimorphism of canines by means of a pioneering artificial intelligence approach to this end.

30 years of the ABFO study: Reproduction in a Brazilian sample.

The ABFO study on third molar development is a benchmark in the scientific literature of dental age estimation. In its 30th anniversary, the study has been reproduced in the present external validation. Standardized comparative outcomes were obtained and discussed across studies.

Personal identification and missing persons initiatives in Santa Catarina state, Brazil: forensic perspectives from 2019 to 2021.

Santa Catarina is a small, developed, and relatively safe state in South Brazil. Despite having positive social economic indicators, it still faces multiple challenges regarding forensic practices for personal identification. The objective of this paper is to discuss the recent advances and current challenges in the region, from the perspectives of anthropological and dental postmortem human identification, missing persons, and disaster victim identification (DVI) from 2019 to 2021.

Facial soft tissue depth measurements in cone-beam computed tomography: A study of a Brazilian sample.

Forensic facial reconstruction (approximation) (FFR) is an aid to human identification when no presumed identity is available. It is based on average soft tissue thickness (STT) applied onto a skull. These averages vary at each landmark according to sex, ancestry, and Facial Growth Patterns (FGP).
