Importância do registro das ausências dentais para a identificação humana: relato de caso / Importance of the registration of dental absences for human identification: case report

Identificar é determinar ou comprovar a identidade de algo, alguém ou de si mesmo, para isso é necessário um conjunto de procedimentos e diligências. O processo de identificação pode ser realizado por diferentes métodos, em casos de cadáveres carbonizados, muitas vezes, o método de escolha para a identificação é o comparativo entre as particularidades odontológicas ante e post mortem. O objetivo deste trabalho é relatar um caso de identificação humana de corpo carbonizado através do método de comparação odontológica. No necrotério do Instituto de Perícias Oficiais local, deram entrada três corpos carbonizados envolvidos em sinistro aeronáutico. O perito odontolegista foi solicitado para participar do processo de identificação de umas das vítimas. O procedimento pericial consistiu na elaboração de um odontograma específico para o corpo não identificado (exame post-mortem) e confronto com os documentos assistenciais (prontuário odontológico) apresentados como sendo da vítima envolvida no acidente (exame ante-mortem). Após a uniformização dos dados Ante Mortem e Post Mortem, os odontogramas foram confrontados gerando o resultado positivo para identificação, destacando-se o registro de várias ausências dentais. Frente ao relato do caso, destaca-se a importância da atuação do cirurgião-dentista no contexto pericial, contribuindo significativamente com a efetividade dos exames realizados, com a celeridade dos resultados, oferecendo uma opção de baixo custo e alta eficiência para a identificação de corpos carbonizados, dispensando outros métodos de identificação

To identify is to determine or prove the identity of something, of someone or of oneself; for this, a set of procedures and diligences are necessary. The identification process can be performed by different methods; in cases of charred corpses, the method of choice for identification is often the comparative between dental and post-mortem dental characteristics. The objective of this work is to report a case of human identification of charred body by means of the method of dental comparison. In the morgue of the local Forensic Institute, three carbonized bodies involved in an aeronautical accident were admitted. A forensic dentist was asked to participate in the process of identifying one of the victims. The expert procedure consisted in the elaboration of a specific dental chart for the unidentified body (post-mortem examination) and confrontation with the assistance documents (dental records) presented as being of the victim involved in the accident (ante-mortem examination). After the standardization of Ante- Mortem and Post-Mortem data, the dental charts were confronted, generating the positive result for identification, highlighting the record of several dental absences. In view of the case report, the importance of the dental surgeon's performance in the expert context is of extreme value, contributing significantly to the effectiveness of the exams performed, with the speed of results, offering a low cost and high efficiency option for the identification of bodies rather than other methods of identification

Correlation between radiographic signs of third molar proximity with inferior alveolar nerve and postoperative occurrence of neurosensory disorders: A prospective, double-blind study

PURPOSE: To evaluate the interference of radiographic factors in the appearance of sensory deficit related to inferior alveolar nerve (IAN) after third molars (3Ms) removal. METHODS: A prospective, double-blind, observational, unicentric study was performed with 126 patients submitted to a surgical procedure of lower 3Ms removal in the period from March to October/2011. Collected data included gender, age, eruption stage of 3Ms, position/angle of 3Ms (Pell-Gregory and Winter classifications, respectively), presence/absence of radiographic signs of 3Ms proximity with the inferior alveolar canal and surgical technique. Occurrence evaluation of the IAN injury was performed on the seventh postoperative day through pin-prick, two-point discrimination and brush directional stroke tests. RESULTS: Predominant radiographic signs were: narrowing of the inferior alveolar canal (68.25%), darkening of root (46.82%) and diversion of the canal (31%). None of the patients presented sensory loss. Sixty-one (48.41%) of the cases had at least one or two radiographic signs of proximity with NAI. Forty-seven (37.3%) had 3 or more signs, and 18 (14.29%) did not have any radiographic signs of proximity to mandibular canal. CONCLUSION: There was not a positive correlation between presence of radiographic signs of 3Ms with IAN proximity and postoperative neurosensory disorders occurrence.
