“…The dental surgeon has an ethical and legal obligation to produce dental radiographs (conventional or digital) and store them properly, for legal purposes or forensic identification (Almeida et al, 2015;Savio et al, 2006). All information in the medical record must be clearly written, duly signed, and dated by the person responsible (Avon, 2004;Almeida et al, 2015). The time of keeping the dental record is a subject of extreme complexity.…”

“…Forensic dentistry is a specialty that provides legal information by collecting, testing, and evaluating dental evidence, which can contribute to clarify several legal aspects, and identify the remains of individuals that cannot be visually recognized, i.e. in situations where the corpse is already in an advanced stage of decomposition, skeletonized, or carbonized (Avon, 2004;Silva et al, 2006;Almeida et al, 2015). According to the Disaster Victim Identification Guide of Interpol, dental identification is considered the primary method of identifying cadavers.…”

“…These data include written notes, studies, radiographs, and photographs, with post-mortem (after death) dental records obtained via forensic examination. Generally, people who have undergone dental care are easier to identify than those with little or no restorative materials in the dental arcade (Pretty, 2007;Almeida et al, 2015).…”

Several radiographs are taken during endodontic treatment, thus providing a large number of images with individual characteristics that can be used for forensic identification of an individual. This study aimed to review the literature related to the use of endodontic radiographs in the identification of cadavers. A bibliographic search was carried out in the following databases: PubMed, Scielo, Periódicos Capes, and Web of Science. The keywords used were: forensic dentistry, endodontics, dental radiography, forensic identification. In total, 24 articles related to radiography in the identification of cadavers were found. Among them, 8 studies were selected for including endodontic radiographs for this purpose, comprising different types of studies: case reports of forensic identification through endodontic radiography (4); “in vitro” studies on the influence of high temperatures on endodontic materials and their radiographic images (2); a literature review on how radiographs can be used for identification (1); a comparative study between antemortem and post-mortem endodontic radiographic images (1). Overall, the present study showed that endodontic radiographs have a significant amount of information that can be used to identify a cadaver. Therefore, it is important to perform and store radiographs properly and for long periods. Literature related to the subject is still scarce and further studies are needed.

“…The former is collected from dental records, while the latter is collected from the cadaver during the autopsy (Silva et al, 2015). Generally, the AM data is provided by the alleged relatives of the victim or directly by dentists that treated the victim in life (Almeida et al, 2015). The search for relatives or dentists is aided by police investigations that narrow the search from lists of missing persons (Almeida et al, 2015).…”

When a single central incisor makes the difference for human identification – a case report

The analysis of dental features and patterns figures amongst the primary means for human identification established by the International Criminal Police Organization (INTERPOL). Differently from fingerprint and genetic analyses, forensic dentistry does not necessarily require a minimum number of similarities between antemortem and postmortem data. In other words, human identification could be achieved from the analysis of a single distinctive tooth or even from a single dental identifier. This study aims to report a case of dental human identification of a charred body. Police investigations were carried out and narrowed the scenario towards a single victim. Fingerprints were destroyed by the fire, hence the relatives of the victim were requested to provide any antermotem dental data. A panoramic radiograph was provided. Developing third molars were visible as well as the endodontic treatment, post and core, and the nonmetallic crown of the maxillary right central incisor (tooth #11). Postmortem radiographs were taken from the cadaver and revealed the same therapeutic dental identifiers found in tooth #11. The observed similarities and the lack of discrepancies between antemortem and postmortem data converged to the positive identification of the victim. This study illustrated the importance of Forensic Dentistry for complex cases of human identification, such as those exposed to fire. Especial attention is driven to the possibility of safely achieving positive human identification with the contribution of a single distinctive tooth.

Quantifying the potential of morphological parameters for human dental identification: part 1—proof of concept

In forensic identification, lack of eccentric characteristics of intact dentitions hinders correct antemortem/post-mortem (AM/PM) matching. It remains unclear which morphological dental parameters hold strong potential as identifiers. This study aimed to establish a method to quantify and rank the identifying potential of one (or a combination of) continuous morphological parameter(s), and to provide a proof of concept.First, a statistic was defined that quantifies the identifying potential: the mean potential set (MPS).The MPS is derived from inter-observer agreement data and it indicates the percentage of subjects in the AM reference dataset who at least need to be considered to detect the correct PM subject. This was calculated in a univariate and a multivariate setting.Second, the method was validated on maxillary first molar crowns of 82 3D-digitally scanned cast models. Standardized measurements were registered using 3D modeling software (3-Matic Medical 12.0, Materialise N.V., Leuven, Belgium): tooth depth, angles between cusps, distances between cusps, distances between the cusps and the mesial pit. A random sample of 40 first molars was measured by a second examiner.Quantifying and ranking the parameters allowed selecting those with the strongest identifying potential. This was found for the tooth depth (1 measurement, MPS=17.1%, ICC=0.879) in the univariate setting, and the angles between cusps (4 measurements, MPS=3.9%) in the multivariate setting. As expected, the multivariate approach held significantly stronger identifying potential, but more measurements were needed (i.e. more time-consuming).Our method allows quantifying and ranking the potential of dental morphological parameters as identifiers using a clear-cut statistic.
