Aim The aim of this study was to compare three phosphor plate intraoral imaging systems (Digora (DA), Digident (DT), Denoptix (DX)) and E-speed conventional film (CF) for the imaging of root canals. Methodology Sixty extracted permanent teeth were ex

To evaluate observers' use of image-enhancement facilities and time consumption in assessing caries in radiographs taken with four digital systems.In total, 131 extracted human premolars and molars were mounted three in a line. Radiographs were taken

This study investigated technical errors in the production of lateral cephalograms necessitating a retake and the extent to which the retake, as ordered by the radiologist, actually produced a gain in quality as assessed by the orthodontist. All the

Medical history is replete with technologies rapidly accepted but quickly disappearing as their lack of benefit becomes evident. The difference between long and short-lasting technologies depends to a large extent on how critical the scientific com

Increasing film speed may potentially jeopardize diagnostic quality because of a more rapid build up of fog and an ensuing decrease in image contrast. A standardized amount of fog was simulated by pre-exposing E-speed dental films before use to obtai
