Comparative evaluation of the sensitometric properties of screen-film systems and conventional dental receptors for intraoral radiography

This investigation determined the sensitometric properties of 27 rare-earth screen-film combinations and compared them to E- and D-speed films and xeroradiolography, the current standards for intraoral radiography. A series of exposures from base plus fog to film saturation were made to determine th...

Summary:This investigation determined the sensitometric properties of 27 rare-earth screen-film combinations and compared them to E- and D-speed films and xeroradiolography, the current standards for intraoral radiography. A series of exposures from base plus fog to film saturation were made to determine the Hurter and Driffield curve of each image receptor. The base plus fog, film saturation, speed, gamma, average gradient, and resolution were determined. When dental receptors and screen-film systems are compared on the basis of radiographic quality (contrast and resolution), many screen-film systems have similar resolution (>10 line pairs/mm), significantly greater contrast (>2.0), and a substantial speed advantage (>10). Thus selected screen-film systems may be an alternative to conventional dental receptors for intraoral radiography.
