摘要: Abstract Objective The diagnostic accuracy of direct digital radiography for the detection small, experimentally made, periapical lesions was compared with that E-speed film. high- and low-contrast resolutions imaging systems were also compared. Study design high-contrast resolution evaluated a line-pair plate. determined contrast-detail plexiglass phantom. To evaluate accuracy, region dry human mandibles examined. Receiver operating characteristic based on readings seven observers generated. Results system inferior, but comparable to For no significant difference seen between areas under receiver curves. Conclusions quality images is film bone lesions.
