Abstract
This study evaluated the accuracy of conventional radiography and photostimulate phosphor plate system in localizing and visualizing experimentally created bone defects.Dry human mandibles with good bone integrity in the evaluated regions were selected. The bone defects were performed on the mandibule external face from the central incisors to the first premolar and within the posterior teeth sockets, using round burs # 2, 4, 6, 8 and 10, in low rotation.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.
