Panoramic radiographs are a relatively simple technique that is commonly used in all dental specialties. In panoramic radiographs, in addition to the formation of real images of metal objects, ghost images may also form, and these ghost images can hinder an accurate diagnosis and interfere with the accuracy of radiology reports. Dentists must understand the formation of these images in order to avoid making incorrect radiographic diagnoses. Therefore, the present study sought to present a study of the formation of panoramic radiograph ghost images caused by metal objects in the head and neck region of a dry skull, as well as to report a clinical case n order to warn dentists about ghost images and to raise awareness thereof. An understanding of the principles of the formation of ghost images in panoramic radiographs helps prevent incorrect diagnoses.
A dilaceração radicular é uma anomalia de forma dentária, geralmente associada a fatores etiológicos traumáticos, na qual há uma mudança de direção da raiz, onde a parte calcificada é deslocada em relação à parte não calcificada, podendo ocorrer em qualquer ponto ao longo do comprimento radicular, dependendo do estágio da formação radicular quando ocorre o trauma, o local e a intensidade. Esta condição acomete cerca de 3% dos dentes permanentes. O tratamento da dilaceração radicular é controverso e o planejamento é essencial. O objetivo deste trabalho é demostrar a importância das imagens radiográficas e tomográficas para o diagnóstico e planejamento do tratamento da dilaceração radicular por meio de um caso clínico.
