Resumo
Um dos mais intrigantes, complexos e controversos desafios da Odontologia Legal é o reconhecimento, registro e análise de marcas de mordidas na pele. Este estudo teve como objetivos: abordar os aspectos relevantes sobre a importância do estudo das marcas de mordidas; produzir informações sobre a ocorrência de casos registrados no Instituto Médico Legal da cidade de Araçatuba-SP, nos últimos cinco anos, envolvendo lesões ocasionadas por mordidas humanas; avaliar comparativamente quatro materiais de moldagem para estudo de marcas de mordidas na pele e testar a aplicabilidade da técnica proposta, por meio de um caso simulado. Foram analisadas 7.550 ocorrências policiais do período de 2001 a 2005. Verificou-se: idade das vítimas, parentesco com o agressor e ocorrência de lesões produzidas por mordidas humanas, bem como, o local mais acometido por tal ferimento. Nas etapas laboratoriais foram utilizados cinco suínos abatidos, com idade média de oito semanas e pesando cerca de seis quilos. Eles foram divididos ao meio e, em seguida, entre dez voluntários foi feito um sorteio sendo que quatro sorteados morderam cada uma das partes, sem conhecimento do pesquisador. A análise das mordidas foi feita de acordo com as normas da ABFO. Foram utilizados os materiais de moldagem: Alginato, Poliéter, Silicone de Condensação e Silicone de Adição. Durante o estudo de caso, a partir dos modelos de gesso e das partes mordidas, foi feita a identificação dos agentes das mordidas, utilizando a técnica da Análise Métrica, e, como controle, a técnica de sobreposições de imagens com uso do Software Adobe Photoshop 7.0. Foram encontrados quarenta e dois casos envolvendo, dentre outros tipos de lesões, as marcas de mordidas. O total de lesões encontradas foi de cinqüenta e seis mordidas: trinta e três pessoas foram vítimas (31 do sexo feminino e 11 do sexo masculino) e oito foram os autores das agressões (todos homens).
One of the most intriguing, complex and controversial challenges of the Legal Odontology is the recognition, registers and analysis of bite mark. This study objectives was: observe the relevant aspects about bite marks analyses importance, using a literature review; demonstrate the prevalence of bite marks in domestic violence crimes involving physical aggression with were collected data in the Police Station of the Woman's Defense in Araçatuba (São Paulo/Brazil); evaluate comparatively four impressions materials for bite marks analysis on skin and test the proposed technique applicability, with a simulated case. 7.550 occurrences policemen of the period from 2001 to 2005 were analyzed. It was verified: the victims' age, relationship with the aggressor and occurrence of lesions produced for bitten human, as well as, the place more attacked by such wound. In the laboratorial phase, it was used five pigs, with eight weeks ages. They were cute, soon afterwards, among ten volunteers it was made a draw and four raffled they bit each one of the parts, without the researcher's knowledge. The analysis of the bites was made in agreement with the norms of ABFO. The molding materials were used: Alginate, Poliéter, Condensation Silicon and Addition Silicon. During the case study, starting from the models of plaster and of the bitten foods, it was made the agents' of the bites identification, using the technique of the Metric Analysis, and, as control, the technique to put upon of images with use of the Software Adobe Photoshop 7.0. They were found forty two cases involving, among other types of lesions, the marks of bitten. The total of found lesions was of fifty six bitten: thirty three people were victims (31 female and 11 male) and eight were the authors of the aggressions (all men).
