Interpretation of artificial and in vivo periapical bone lesions comparing conventional viewing versus a video...

The purpose of this study was to compare the interpretation of conventional radiographs transmitted by a video teleconferencing system to conventional viewbox interpretation for both artificial and in vivo periapical bone lesions. A total of 30 radiographic images were used in this study: 20 radiographic images of artificial lesions and 10 radiographs from actual patients. Two endodontists evaluated the 30 images by giving a "yes" or "no" response when determining whether a periapical lesion was present on the radiograph. The study was conducted in two sessions, separated by a 6-wk interval to minimize evaluator recall. Results of the study revealed no statistical difference between the ability of the evaluator to identify periapical bone lesions using conventional radiographs on a viewbox and his ability to interpret the same images transmitted on a monitor screen.
