The temporomandibular joint (TMJ) is the joint between the mandibular condyles, the mandibular fossa and the articular tubercle of the temporal bone. TMJ has been described as a “bicondylar” joint, a term that in current literature is used in multiple and dissimilar contexts. We present a scoping review of the term “bicondylar” as a descriptive ter...

We present an integrative review of the literature conducted to find and analyse specific measures for disinfection and/or sterilization of intraoral complex instruments, applicable to intraoral scanners. We performed a two-stage search in the PubMed/MEDLINE, SciELO, REDALYCS, and LILACS databases, and the Google Scholar website, which included ful...
Article
Full-text available
Taphonomy, a concept recognized in paleontology and anthropology, allows the estimation of time and circumstances of death by studying post-mortem conditions and factors related to the survival of bone remains. Among the different taphonomic variables, Binford (1981) proposed a categorization of bite marks, now recognized as standard for these stud...
Article
Sex estimation is the keystone for positive identification when an unidentified human body is recovered in forensic contexts. However, in complex death scenes such as mass disasters, the remains are often fleshed, mutilated, burned, and/or commingled. In situations such as these where it is not possible to analyze pelvis and/or cranium data, tradit...
Article
The aim of this work was to study the sexual dimorphism of the occlusal surface of the maxillary postcanine dentition using geometric morphometric techniques. This study evaluated 139 individuals as part of five osteological collections from municipal cemeteries in the province of Granada (Spain). The landmarks and semilandmarks were analysed by pr...

Objective: The aims of this study were to assess the reliability, reproducibility and validity of mesiodistal and buccolingual measurements comparing these measurements collected using an electronic hand-held digital calliper, on dry dentitions and on dental casts, with measurements obtained from 3D digital models created using a portable intra-or...
Article
Lip print identification has been proposed as an additional tool for crime investigation because of the supposed uniqueness of labial grooves; however, critics of the validity and reliability for methods and techniques redefined standards and requirements in order to consider this discipline a real forensic identification science. During our resear...

Article
Paleopathology is the science that studies the origin and evolution of diseases. The interest in this discipline derives from the fact that the frequency and distribution of the pathologies that have affected the extinct species, correlate with their ecology and ethology. This assumption is also valid in the case of Carcharocles megalodon, the larg...

Article
Estimating the sex of immature skeletal remains is important when reconstructing the biological profile of unknown individuals in anthropological practice. Teeth have a distinct importance as they are the most frequently recovered physical elements of an individual. They persist after death due to their hardness and resistance to postmortem insults...
Article
Full-text available
Lip print analysis for criminal identification has been called Cheiloscopy, a specialty of forensic odontology based on the alleged uniqueness, durability and classification of labial groove patterns. Presently, there are two basic claims that seem to make reference to Cheiloscopy in the forensic world: While some cases have distinctly marked its d...
Article
Sex determination of unknown individuals is one of the primary goals of Physical and Forensic Anthropology. The adult skeleton can be sexed using both morphological and metric traits on a large number of bones. The human pelvis is often used as an important element of adult sex determination. However, studies carried out about the pelvic bone in su...

After publication of the original article, it was brought to authors' attention two errors that were included in the final publication.
Article
Full-text available
In archeology or forensics, the analysis of the ilia is often used to determine the age and sex of unknown individuals. However, sex determination using the skeletal remains of individuals who did not develop secondary sexual characteristics remains controversial. Accurately estimating the sex of subadults is hampered by a small number of studies b...
Article
This study details a severe case of Scheuermann’s disease (SD) in a well-preserved skeleton of a juvenile male (designated TOR302), dated to 3rd–4th century CE, from the late Roman necropolis of Torrenueva (Granada, Spain). Individual TOR302 shows an evident kyphotic curve in the thoraco-lumbar spine, which is characterised by: (i) vertebral bodies...
