“…The most frequent parameter for forensic dental comparative study was radiographic comparison. Radiological analysis makes it possible to verify the compatibility of radiographic images related to the morphology of anatomical structures and therapeutic restorative interventions in the teeth 14 .…”

ResumoIntrodução: A identificação humana é uma das principais etapas referentes às questões relacionadas à pessoa desaparecida. Objetivo: O presente estudo visou avaliar a efetividade da identificação humana pelas perícias odontolegais realizadas no Serviço de Antropologia Forense de Belo Horizonte-Minas Gerais, comparando-as com as realizadas por DNA. Metodologia: Estudo transversal, utilizando dados secundários registrados no arquivo do Setor de Antropologia Forense, considerando o período de 2008 a 2014, referente às perícias de identificação odontolegais e DNA. Resultado: Analisando-se apenas as perícias de interesse deste estudo (241), a análise de DNA foi o método utilizado para identificação em 79,3% dos casos e exame odontolegal, 20,7%. Quanto ao tipo de material biológico encaminhado para análise, os cadáveres desconhecidos totalizaram 131 (53,9%), as ossadas 109 (44,9%) e segmentos corporais 3 (1,2%). A análise do tempo efetivamente despendido para a conclusão dos exames mostrou que os realizados pela Odontologia foram mais rápidos que os de DNA. No exame odontolegal, o tempo gasto independe do tipo de documentação odontológica avaliada. Conclusão: A análise dos resultados do presente estudo mostrou que a identificação humana pela técnica odontolegal é eficaz, mais ágil e menos onerosa, contribuindo para uma maior celeridade na resolução de questões envolvidas na localização de pessoas desaparecidas. Descritores: Antropologia forense; odontologia legal; genética forense; identificação biométrica. AbstractIntroduction: Human identification is considered one of the major steps concerning missing people. The Forensic Anthropology Sector of Legal Medical Institutes identifies corpses. Forensic dentistry and DNA tests stand out among the existing standard tests. Objective: This article aimed to evaluate human identification effectiveness through forensic dental examination performed in the forensic anthropology sector in a Forensic Medical Institute, comparing them with DNA analyses. Methodology: This is a cross-sectional study using secondary data available in the department´s database, from 2008 to 2014, concerning identification procedures using forensic dentistry and DNA techniques. Result: The analysis of the examinations eligible to this study (241) showed that DNA analysis was the method used for identification in 79.3% of the cases and forensic dental examinations were used in 20.7% of the cases. As for the type of biological material used during these examinations, unidentified corpses corresponded to 131 cases (53.9%), skeleton structures corresponded to 109 cases (44.9%) and there were 3 cases of body segments (1.2%). When analyzing the time spent to complete the tests, dental examinations were faster than DNA tests. The time spent for forensic dental examination does not depend on the type of dental documentation evaluated. Conclusion: The analysis of the results in this study showed that human identification through forensic dentistry is effective, rapid and less costly, contributing to greater ...

“…This allows for qualitative evaluation by underscoring small changes such as caries progression, periapical lesions, or even quantitative evaluation of periodontal bone loss. [ 4 ] Forensic dentistry uses radiology in determining the age of an individual by assessing the stage of eruption of teeth as well as for evidence in the identification of the suspect, to determine the cause of death, to find faulty charting of teeth, legal matters, body identification, postmortem examination, and for nonaccidental injuries of children and forensic anthropology. [ 5 ] In evaluating cysts or benign tumors, multiplanar sections (axial, coronal, and sagittal planes) are helpful to locate deeper tissues.…”

“…In forensics fields, the unique characteristics of human dentition are widely accepted for identification. Because of these advantages, forensic odontology is considered as a dependable and reliable method of human identification (Andersen et al 1995;Delattre 2000;Pretty and Sweet 2001;Koehler and Brown 2009;Verma et al 2014;Priyanka and Prasad 2015).…”

“…One of the great improvements in this area is the assimilation between forensic dentistry and information technology such as dental imaging techniques, bite-mark analysis, and preservation of the dental records (Heinrich et al 2018). The common digital imaging technique which is used in dental identification is carried out using the two-dimensional (2D) approach, such as comparisons of radiographic images, photographs, and visual identification (Manigandan et al 2015). In addition to 2D imaging, many studies use the three-dimensional (3D) imaging systems to obtain more accurate and precise results in forensic identification (Evans et al 2010;Pramod et al 2012; Abduo and Bennamoun 2013; Ata-Ali and Ata-Ali 2014).…”

Background: The assimilation between three-dimensional (3D) imaging techniques and dental forensic science can provide rich and stable information for human identification. This study aimed to determine the effective number and surfaces of teeth for dental identification through the 3D imaging approach. Material and methods: In the present study, maxillary dental casts were fabricated from subjects who met the inclusion criteria and scanned using a 3D scanner Vivid 910. Rapidform XOS/SCAN software was used to create and trim the 3D point cloud data. Subsequently, two types of 3D surface data of dental casts were registered and the root mean square errors (RMSEs) between subjects were calculated using iterative closest point (ICP) algorithm in MATLAB. Two sets of experiments with 120 combinations of the superimposed 3D dataset were designed, termed as experiments 1 and 2. Results: In experiment 1, the difference between subjects was clearly distinguished with a minimum of six teeth of the dental arch. The results of experiment 2 suggest that the labial surfaces of the anterior teeth are sufficient to be used for dental identification. Conclusion: Through these experiments for all possible pairs of subjects, a clear difference was observed in the RMSE between the genuine and imposter pairs. These results indicate the potential of using the 3D imaging technique to achieve highly accurate human identification. It is suggested that a future study with a larger sample number will evaluate the robustness and accuracy of this method.
