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)...

Unavailability of chronological age brings to the forefront the importance of age estimation for human identification. Dental age is routinely assessed based on the calcification stages and/or the eruption of teeth, which exhibit wide variations amongst different ethnic groups. The current study aimed at estimating the dental ages in 384 South Indian subjects aged 6-21 years, using clinical and radiographic methods and comparing the predictive accuracy of these two dental age estimation methods. For the estimation of age by clinical method, Foti and co-workers' mathematical Model 2 was employed and for the radiographic method, Chaillet and Demirjian's method with Acharya's Indian formula was used...

Quality assurance or quality control is a term and concept coming from the industry. Here it is most important. All products must have a minimum quality and variation in size, for example, must be kept within certain strict limits. There must be a system to control this. May be not every single product is controlled, but spot tests must be taken. Measures must be taken to improve the quality if it is not good enough. This concept has been transferred to medicine, odontology, and consequently also to forensic odontology...

When the age of an individual is unknown, age assessment refers to the procedures through which authorities try to establish the chronological age of an individual. Dental evidence demonstrated to be very effective in estimating age and dental mineralization is largely deemed a process scarcely influenced by major diseases and nutritional or environmental factors which can affect child growth. This research aims to understand the possible influence of genetic syndromes on dental maturation of affected individuals...

Saliva is one of the most commonly encountered biological fluids found at the crime scene. Forensic science including forensic odontology is focused on the positive identification of individuals. The salivary protein profiling can help in personalization by the changes associated with age throughout life and gender. These changes also seem to vary with the dietary habits, environmental factors and geographical areas. Thus, the aim of present study is to estimate these changes in salivary total protein concentration and profiling in individuals of Gujarat, India...

Computer Tomography (CT) and Magnetic Resonance Imaging (MRI) may be useful tools in assessment of age of an individual. This article presents a review of published studies using CT or MRI in dental age estimation. They were published between July 2004 and September 2017 investigating different types of teeth, methods and formulae for age estimation. Twenty-seven articles were included. The different studies show good results, and it seems that a combination of different types of teeth, methods (depending on the degree of root formation) and cooperation between different disciplines in the same study gives a higher accuracy...

BACKGROUND: The Demirjian method has been the most widely tested method for the estimation of the dental age of children and adolescents. However, only three studies have compared Demirjian's original and revised seven-tooth methods, four-tooth method and alternate four-tooth method, none of them conducted on an Indian population. AIM: The present study aimed to compare the applicability of the original and revised seven-tooth and four-tooth and alternate four-tooth standards for age estimation of 1200 Indian children aged 5-15 years old...

The migratory flows to Europe from the African countries, Asia and Middle East, have hugely intensified in the recent years. In 2016, more than 98,000 out of a total of 260,000 migrants across the Mediterranean Sea arrived in Italy and in May 2017, the trend of arrivals is: Italy +576%; Greece -39% compared to previous years. Some migrants die before touching the sole of the European continent, during the crossing, often afforded with ships, made available by unscrupulous smugglers or criminal organizations, which are unsuitable for this type of transportation...

BACKGROUND: The development of third molars can be evaluated with medical imaging to estimate age in subadults. The appearance of third molars on magnetic resonance imaging (MRI) differs greatly from that on radiographs. Therefore a specific staging technique is necessary to classify third molar development on MRI and to apply it for age estimation. AIM: To develop a specific staging technique to register third molar development on MRI and to evaluate its performance for age estimation in subadults...

BACKGROUND: Gradual obliteration of the Periodontal Ligament Visibility (PLV) of lower third molars indicates increasing age. This is used to help determine whether or not an age disputed subject is above or below the 18 year threshold. AIM: The main focus was to determine, in test subjects of known age, whether the PLV system used 'blind' is able to reliably indicate whether the subject was a child (age < 18 years) or adult (age > 18). MATERIALS AND METHODS: A total of 250 normal subjects in the age range 16 to 26 years, from the archives of Guy's Hospital in London, UK, were used to validate the system of PLV...

BACKGROUND: The ability of cervical vertebrae (CV) staging to contribute in forensic age estimation is being discussed controversially. The large variability of CV geometries in the end stage of development might be the reason for not reaching a performance competitive to hand or third molar methods. Here we study the geometry of adult CV and demonstrate that the description of their "typical" appearance is often not met. MATERIALS AND METHODS: Lateral cephalograms from clinical routine of 320 subjects aged 20 years or above (median 24 years, 52% female) were evaluated...
