In developed countries, violence is the main cause of oral maxillofacial (OMF) injuries. In Brazil, there are scant records of such lesions. The scope of this study was to detail the OMF injuries resulting from physical aggression in a capital of the Brazilian northeast and analyze gender differences. The Forensic Medicine Institute of São Luís, state of Maranhão, featured 15,847 reports, which occurred in 2012, and they were investigated. Socioeconomic, demographic data and OMF characteristics were analyzed...

Regressive dental changes appear to be suitable for age assessment in living adults. In 2012, Olze et al. showed that several criteria presented by Gustafson for extracted teeth can also be applied to orthopantomograms. The objective of this study was to test the applicability and reliability of this method in a Chinese population. For this purpose, 1300 orthopantomograms of 650 female and 650 male Chinese aged between 15 and 40 years were evaluated. The characteristics of secondary dentin formation, periodontal recession, attrition, and cementum apposition were reviewed in all the mandibular premolars...

Context: Tooth plays a pivotal role in the identification of a person when all other remains are ruined by natural or unnatural causes. Dental evidence can contribute to age estimation in forensic dentistry. Estimating the age of an individual with the help of a tooth for identification proves beneficial. Alternating light and dark bands seen on the cementum have been shown to be proportionate to the age of the patient in number. This was done to evaluate the cementum annulation in age determination...

Social media applications can be valuable investigative tools in the search for missing and unidentified persons. As yet, no forensic App exists with the aim of assisting the human identification process, through the search of antemortem data to be used as adjunct data in the comparison with postmortem data collected. The aim of this article is to introduce a new application for Smartphones called "Selfie Forensic ID" App which will employ selfie and face photographs as an archive of dental data and dental features of the front teeth of missing persons sharing with Instagram, Tumblr, and Twitter Social Networks (available for free download from both Android and Apple store at http://onelink...

Child sexual abuse (CSA) is defined as inappropriate adolescent or adult sexual behavior or contact with a child. Sexual abuse may be committed by any person including those under the age of 18 years when that person is either significantly older than the victim or is in a position of power or control over the child. Detecting CSA requires a high incidence of suspicion and familiarity with physical, behavioral, and verbal indications of abuse. Shame and guilt often may have discussion difficult. Studies have shown that approximately 60% of abused children have injuries to head, face, and mouth...

Forensic odontology is the application of dental principles to legal issues. It is an investigative aspect of dentistry that analyzes dental evidence for human identification. Sex determination is a subdivision of forensic odontology, and it is important especially when information relating to the deceased is unavailable. Sex determination becomes the first priority in the process of identification of a person by a forensic investigator in the case of mishaps, chemical and nuclear bomb explosions, natural disasters, crime investigations, and ethnic studies...

Taurodontism is an anomaly that affects posterior teeth, vertically increasing the size of the pulp chamber, mimicking the shape of bovine teeth, being only evidenced in diagnostic images. This report describes a case of taurodontism in a mandibular second molar, highlighting the forensic importance of this dental anomaly with relevant potential for human identification, not only for its morphological aspect but also for its relatively low frequency in mandibular second molars. In the case under study, the individual did not have any restored teeth...

Age estimation is guided by the evaluation of events that happen during the processes of bone and dental development. The purpose of this study was to validate the method of age estimation proposed by Lajolo et al. (2013) through oro-cervical radiographic indices in Brazilians. The study aimed to verify the effectiveness of age estimation equations through dental and cervical vertebrae examinations, in addition to including dental and cervical vertebrae data in new age estimation equations. The sample consisted of panoramic radiographs and teleradiographs from 510 subjects (8-24...

The aim of this study was to evaluate the effect of earth and water on the colour stability of tooth-coloured dental restorative materials: composite resin (CR) and glass ionomer cement (GIC). Aiming to distinguish between one and another tooth-coloured material and to estimate the period in which they could be submitted to the factors earth and water, the proposed method may contribute to the proceedings of human identification of victims of burial and submersion in water. Forty bovine incisors were prepared (6 x 6 x 2mm) and restored with CR FiltekTM Z250 XT (3M ESPETM) and GIC KetacTM Fil Plus (3M ESPETM)...

PURPOSE: The aim of this survey was to determine whether forensic odontology forms part of the basic dental program in the nine Australian dental schools, which aspects of forensic odontology were taught, and the barriers and issues that prevent forensic odontology being part of any dental curriculum. The survey also examines the teaching of cranio-facial anatomy and dental record keeping, as these two subjects can play an important role in clinical forensic odontology. MATERIALS AND METHODS: STUDY DESIGN AND PARTICIPANTS: A postal questionnaire survey on the teaching of forensic odontology was conducted between November 2016 to April 2017, being sent to the dean of school, head of school, or acting head of school, each representing the nine Australian dental schools...

Introduction: Teeth are an excellent material in living and nonliving populations for anthropological, genetic, odontologic and forensic investigations. Among the various calcified structures in the human body, teeth have gained lot of popularity in estimating the sex of an individual as they are highly resistant to destruction and decomposition. The present study aims to assess the importance of canines in sexual dimorphism in both primary and permanent dentition as well as to describe the dimensional characteristics of canines among the population of Bagalkot district of Karnataka, India...

Background: Palatal rugae are nonidentical mucosal elevations seen on anterior third of palate. They are arranged in transverse direction on either side of the mid-palatine raphe. Although they are the most stable anatomical structures in the oral cavity, certain conditions such as expansion in orthodontic treatment contribute to some amount of variations in their pattern qualitatively. The aim of this study was to compare the shape of rugae and its positional changes before and after rapid maxillary expansion...

Aims: Detailed description and study of teeth traits could provide valuable information regarding phylogeny of man and distinctions between races and subraces. But morphological variations of the human dentition have not been utilized to their full potential by anthropologists concerned with patterns of human biological variation in Indian population. The aim of the present study is to detect the frequency and degree of expression of Carabelli's trait in Bengaluru population, this helps to develop a probabilistic model to distinguish individuals from specific human populations, particularly for forensic purposes...

Forensic age estimation of a living individual is frequently performed in clinical forensic medicine. Medicolegal physicians are usually called upon by the authorities to estimate the age of a living person requesting asylum or to determine whether a suspected offender is subject to juvenile or adult criminal law. Dental age is one of the parameters studied to estimate biological age. Several methods are used, and among these, analysis of the eruption of the third molar (M3) on an orthopantomogram (OPG) is one of the common methods...
