Tomografia computadorizada como método auxiliar no diagnóstico e tratamento de lesões intra-ósseas: caso clínico de odontoma composto
Abstract
O advento da tomografia computadorizada (TC) possibilita de visualização tridimensional, favorece o diagnóstico e proporcionando um tratamento mais preciso em virtude da localização exata da lesão e análise da proximidade com as estruturas anatômicas vitais relacionadas. Contudo o tratamento de lesões ósseas se torna mais segura, reduzindo o risco de lesão a dentes adjacentes e nervos. O Odontoma é considerado o tumor odontogênico que mais comumente acomete os ossos maxilares. A variante composta deste tumor apresenta a característica de muitas estruturas semelhantes a dentes envolvidas por um halo radiolúcido e grande freqüência na região anterior da maxila, porém o diagnóstico deste tumor nas demais localizações dos maxilares é pouco freqüente. Apresenta normalmente crescimento limitado e expande as corticais ósseas, porém sem tendência à recidiva. O tratamento do odontoma consiste na sua excisão cirúrgica. Os autores pretendem relatar a utilização da TC como método auxiliar no diagnóstico e tratamento de um caso de exérese de um odontoma composto na região anterior da mandíbula.
UNITERMOS: odontoma; tomografia; implante dentário.
SUMMARY
The advent of computed tomography (CT) has possibility of tridimensional visualization, corroborating to diagnosis and precise treatment throung of lesion localization and analysis of related vital structures proximity. However, the treatment of bone desease done more certain. Lesions decrease risk for nerves and adjacents teeth. Odontoma is considered the most common odontogenic tumour of the jaws. The compound type is characterized by many tooth-like structures surrounded by a radiolucent envoltory and has great frequency in the anterior maxilla. This lesion has limited growth pattern no tendency to recurrence but may expand cortical bone. The treatment of the odontoma consists of its excision. The authors present a case of CT used as auxiliary method of diagnosis and treatment a case of excision of a compound odontoma in the anterior mandible.
UNITERMS: Odontoma, tomography, dental implantation.
