ABSTRACT
O objetivo neste estudo foi comparar a precisão das imagens radiográficas realizadas com posicionadores de três diferentes marcas: Rinn XCP utilizando localizador curto e longo, Hanshin e lndusbello com localizador curto. As médias das medidas radiográficas foram calculadas e comparadas com o tamanho original dos dentes. Os resultados foram submetidos à análise de variância e ao teste de Tukey com a=0,05. Todos os posicionadores analisados ampliaram o tamanho da imagem sendo que o da Rinn XCP com localizador longo promoveu a menor ampliação. Não houve diferença estatisticamente significativa entre Rinn XCP com localizador longo e Hanshin. Os posicionadores da técnica da bissetriz e do paralelismo, quando utilizados com as distâncias recomendadas, possibilitaram a obtenção de mensurações dentárias próximas ao tamanho real.
The objective with this work was to compare the radiographic images precision of the dental elements accomplished with film holders of three different brand: RINN XCP used short and long beam-indicating devices, HANSHIN and INDUSBELLO used short beam-indicating devices. The mean measurements of radiographic image were calculated and compared with the teeth length size. All the film holders analyzed promoted the magnified radiographic and the RINN XCP's film holders with long beam indicating device promoted the minor magnified. No significant differences were found among RINN XCP's film holders with long beam-indicating device and HANSHIN. The film holders for the parallel and bisecting-the-angle technique when used with the recommended distances make possible to obtain radiographic image measurements close tooth length size.

A radioterapia tem atualmente um papel fundamental no tratamento do câncer de cabeça e pescoço. Dois terços dos pacientes com câncer recebem em alguma fase de sua doença tratamento com radiações, seja como tratamento exclusivo ou associado à cirurgia e/ou quimioterapia. As principais conseqüências orais decorrentes da radioterapia de cabeça e pescoço são mucosite, xerostomia, perda do paladar, trismo, cárie de radiação, candidíase e osteorradionecrose. É de fundamental importância que o cirurgião dentista esteja familiarizado com tais complicações para que possa juntamente, com a equipe oncológica, prevenir, controlar e tratar tais conseqüências. O objetivo deste estudo é apresentar as principais complicações orais advindas da radioterapia e descrever a conduta clínica geral em pacientes antes, durante e após o tratamento radioterápico

This reports a case of peripheral osteoma occurring at the mandibular border in a 16-year-old girl. Clinically, a swelling with a hard surface was observed at the inferior border of the right mandibular body, causing facial asymmetry. Radiographic examination revealedradiopacity and a well-circumscribed mass approximately 2 cm in size. The lesion was treated surgically. The histopathological evaluation revealed features compatible with osteoma, such as vital compact and mature medullary bone tissue, showing osteocytes and medullary spaces containing a loose connective tissue with capillaries.There was no evidence of any recurrence
