Several forensic sciences, especially of the pattern-matching kind, are increasingly seen to lack the scientific foundation needed to justify continuing admission as trial evidence. Indeed, several have been abolished in the recent past. A likely next candidate for elimination is bitemark identification. A number of DNA exonerations have occurred in recent years for individuals convicted based on erroneous bitemark identifications. Intense scientific and legal scrutiny has resulted. An important National Academies review found little scientific support for the field...

In the post-mortem examination of the dental arches of accident victims in cold locations, dental restorative materials can be found. Cold temperatures can be capable of causing color changes of aesthetic materials, such as composite resin (CR) and glass ionomer cement (GIC). The aim of this study was to evaluate the effect of the cold action on the color stability of CR and GIC restorations, in order to discriminate them and enable the adequate comparison between antemortem and post-mortem data. Sixty bovine teeth (30 CR and 30 GIC) were prepared (6 × 6 × 2 mm) and separated into groups (n = 10)...

Fatalities due to fire events such as bushfires, domestic and industrial fires and vehicle accident related incineration, leave victims with limited prospects of being accurately identified. Due to their morphology and anatomical position teeth are uniquely protected in incineration cases and via comparison to dental records often provide the only scientifically valid means of identification. However, extreme heat and direct exposure to flame can render the teeth extremely fragile and vulnerable to damage and loss especially during collection and transportation to the mortuary...

BACKGROUND: Human identification can be reliably established by dental comparison; success is significantly impacted by inadequate antemortem information. Previous Australian research revealed suboptimal recording of features important for forensic dental identification and compliance with Dental Board of Australia guidelines. We hence created and evaluated an online education programme aimed at improving oral health practitioner recording. METHODS: An Interactive Learning Module (ILM) was constructed and released to three focus groups representing practitioners with varying experience levels - Australian Society of Forensic Odontology members, third year dental students and the wider dental community...

The study of identical twins can point out potential limitations in biometrics and forensic odontology. This case report presents three-dimensional (3D) palatal rugae analysis in monozygotic twins utilizing digital models obtained directly by scanning the maxillary dental arch with the iTero® intraoral digital scanner. The results show that the rugae patterns contain related but not identical features between the pair of identical twins. Dental study models taken on a regular basis for diagnosis and treatment planning in dentistry include the palatal rugae, which could be valuable to forensics in identical twin identification cases...

Forensic Odontology a branch of Forensic sciences uses the skill of the dentist in personal identification during mass calamities, sexual assault and child abuse to name a few. This branch not stranger to many has been growing tenfold in its potential and its ability to bring the forlorn to justice where a dental remains is the only available evidence. It's role and importance in the judiciary is fast growing and hence in depth knowledge in this field seems more than justified.

Forensic Odontology is a specific means for identifying a person in which deceased, and particularly in fatality incidents. The algorithm can be proposed to identify a person by comparing both postmortem (PM) and antemortem (AM) dental radiographs and photographs. This work aims to introduce a new mathematical algorithm for photographs in addition with radiographs. Isoperimetric graph partitioning method is used to extract the shape of dental images in forensic identification. Shape matching is done by comparing AM and PM dental images using both similarity and distance measures...

Forensic odontology is a sub-discipline of dental science which involves the relationship between dentistry and the law. The specialty of forensic odontology is applied in radiographic investigation, human bite marks analysis, anthropologic examination and during mass disasters. Besides the fact that radiographs require pretentious laboratory, it is still claimed to be a facile, rapid, non-invasive method of age identification in the deceased. The budding DNA technology has conquered the traditional procedures and currently being contemplated as chief investigating tool in revealing the hidden mysteries of victims and suspects, especially in hopeless circumstances...
