BACKGROUND:Lichen planus is considered to be the most common dermatological disease involving
the oral mucosa.OBJECTIVE:To investigate the profile, clinical features, and the presence of dysplasia and
candidiasis in patients with oral lichen planus.METHODS:A total of 21 patients were selected from 258 patients at risk for oral cancer
development.RESULTS:Most of the patients were white (76,2%), female (66,6%), with mean age of 58.8
years. Eight were smokers and seven were alcohol consumers. The buccal mucosa was
the most affected site, followed by the tongue and the gingiva. The reticular
pattern was the most common appearance. Histopathology depicted dysplasia in nine
cases and cytopathology was positive for Candida in eight cases in the first
appointment.CONCLUSION:Our data are similar to the literature. Cytopathology was important for the
diagnosis of candidiasis. Although the presence of dysplasia was verified, further
studies are necessary to clarify the importance of this finding.
In addition to clinical examination, forensic odontologists can use diagnostic imaging as an auxiliary method for identification. This paper reports a case where forensic odontologists from the Afrânio Peixoto Legal Medicine Institute in Rio de Janeiro (Brazil) positively identified a carbonized and partially calcined body using oral and maxillofacial imaging. The cadaver showed several metallic plates fixed with metallic screws on bones of the neurocranium and viscerocranium. Family members provided spiral computed tomography scans of the skull and a panoramic radiograph that were acquired after an accident that required surgical procedures. Comparative analysis between the clinical exam and the maxillofacial images demonstrated complete coincidence, confirming the victim's identity. Dactyloscopy, which is the most commonly used method of identification, was not possible because of the body carbonization. Thus, diagnostic imaging, especially computed tomography, was essential for elucidation of this case.
Introdução: A imaginologia odontológica é de grande relevância para a identificação humana, sendo frequentemente utilizada pela Odontologia Legal para este fim. O correto arquivamento dos exames de imagem nos prontuários dos pacientes permite a comparação de dados ante e post mortem. Objetivo: O presente trabalho objetivou descrever a determinação da identificação de um indivíduo carbonizado por meio da imaginologia odontológica. Relato de caso: As documentações fornecidas pela família da vítima foram uma foram confrontadas com aquelas obtidas pelas radiografias periapicais dos dentes realizadas pelos peritos. Foram encontrados os seguintes pontos coincidentes após o confronto das informações entre os exames ante-mortem e post-mortem: giroversão dos dentes 34, 43 e 44; aposição de dentina secundária nas câmaras pulpares dos dentes 36, 37, 46, 47 e 48; cárie oclusal do dente 36 e trabeculado ósseo com características anatômicas individuais em região de molares inferiores nos lados direito e esquerdo, resultando em uma identificação positiva. Conclusão: Assim, conclui-se que o confronto entre as radiografias ante-mortem e post-mortem é uma ferramenta fundamental no processo de identificação em Odontologia legal. Entretanto, essa técnica apenas pode ser aplicada com a existência de arquivos anteriores para comparação. Logo, é importante enfatizar a importância da manutenção e do correto arquivamento de exames de imagens odontológicos obtidos durante o tratamento do paciente, pelos cirurgiões-dentistas.
