Although well studied since the 50's, bruxism remains a largely unknown pathology. Its origin is complex, mixing psychological as well as neurological, odontological and hypnic aspects. However, the few analyzes performed on this topic have allowed to set convincing etiopathological hypotheses, including central dysregulation of the dopaminergic system as well as of the neuro-masticatory system. To avoid harmful consequences as headaches, temporomandibular disorders and premature dental scuffs / fractures, it is mandatory to diagnose bruxism as early as possible...

BACKGROUND: Obstructive sleep apnea (OSA) is one of the common prevalent conditions present worldwide. The process of abnormal habits related to clenching and grinding of teeth is referred to as bruxism and is characterized under the heading of parafunctional activity of the masticatory system. Osseointegrated dental implants represent advancements in the field of odontology. Despite its high success rate, failure and complications are often associated with dental implant treatment due to a number of factors...

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...

Hypophosphatasia is a very rare bone metabolism disorder caused by a deficiency in alkaline phosphatase activity, due to mutations in the ALPL gene. Its clinical hallmark is the impairment of skeletal and teeth mineralisation, although extra-skeletal manifestations are frequent. Its phenotypic spectrum is widely variable from a subtype with exclusive odontological impairment (odontohypophosphatasia) to five subtypes with systemic involvement, classified according to the age at the onset of the first symptoms (four of them in the paediatric age range: perinatal lethal, perinatal benign, infant and childhood hypophosphatasia)...

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...

BACKGROUND: Human identification is one of the most challenging subjects that human has been confronted with. Through the ages, odontological examinations have been a critical determinant in the search of human identity. Data in the form of age, gender, and blood group might provide vital clues in such investigations. In the recent times, it has been often desirable to preserve tissues for further investigations following the unfolding of certain events or discovery of new data. Hence, it is important to gather as much data as possible using less tissue...

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.
