Mark Page, Russell Lain, Richard Kemp, Jane Taylor
As part of a series of studies aimed at validating techniques in forensic odontology, this study aimed to validate the accuracy of ante-mortem (AM)/postmortem (PM) radiographic matching by dentists and forensic odontologists. This study used a web-based interface with 50 pairs of AM and PM radiographs from real casework, at varying degrees of difficulty. Participants were shown both radiographs as a pair and initially asked to decide if they represented the same individual using a yes/no binary choice forced-decision...

Forensic odontology is an evolving science and has a greater scope of development. It has established as an indispensable science in medico-legal matters and in the identification of the dead person. The dental tissues are often preserved even if the deceased person is skeletonized, decomposed, burnt, or dismembered. Various methods have been developed to determine age, sex, and ethnicity of the person, using dental tissues. Data collection methods and supplementary technologies used in forensic dental identification have undergone significant transformation...

Developmental malformations of the teeth might result in alterations of their size, shape, and structure. An accessory cusp is a developmental alteration to the shape of the teeth and is more commonly found in anterior teeth, and its occurrence in permanent molars is quite rare. Accessory cusps occurring in permanent mandibular molars are termed as protostylids. Although they do not pose any significant problem with respect to the function and occlusion, it is of tremendous importance in forensic odontology...

Geoffrey H Sperber
This paper reviews the surface ablation of early hominin teeth by attrition, abrasion, and erosive dental wear. The occurrence of these lesions is explored in a sample of South African fossil australopithecine dentitions revealing excessive wear. Interpretation of the nature of the dietary components causing such wear in the absence of carious erosion provides insight into the ecology of the Plio-pleistocene epoch (1-2 million years ago). Fossil teeth inform much of the living past by their retained evidence after death...

Personal identification methods may not be efficient when bodies are decomposed, burned, in cases of mass disasters when soft tissue cannot provide reliable information or has been lost. Various methods currently employed in forensic odontology for personal identification include comparing with antemortem dental charts, rugoscopy, denture labeling, DNA analysis from dental pulp, bite mark analysis, etc., Recently, there is growing interest in the study of enamel rod end patterns. These enamel rod end patterns are termed as "Tooth prints" and the study of these prints is known as "Ameloglyphics" (amelo: Enamel, Glyphics: Carvings)...

When human remains are found, the priority of the investigation is to ascertain the identity of the deceased. A positive identification is a key factor in providing closure for the family of the deceased; it is also required to issue the death certificate and therefore, to settle legal affairs. Moreover, it is difficult for any forensic investigation involving human remains to be solved without the determination of an identity. Therefore, personal identification is necessary for social, legal and forensic reasons...

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 ante-mortem 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...
