Análise de Defeitos Ósseos Utilizando a Radiografia Convencional e Sistema de Imagem Digital Digora

The mandibles were radiographed with Ekta-speed Plus EP-21 Kodak film and optical plates of the Digora system. The visualization of bone defects was performed in the radiographic images, with the aid of a viewbox; in the digital images (standard, 3D, contrast inversion), it was performed in the computers screen, with the support of Windows for Digora software. The findings showed that the bone defect in cortical bone are best viewed in conventional radiography and in cancelous bone are best in digital images. When digitized images were compared it was observed that standard and contrast invertion images were more accurate than those in 3D, in the visualization of bone defects.
