title: Approximal carious lesion depth assessment with insight and ultraspeed films.
abstract: This study evaluated the efficiency of a new E/F-speed film, Insight, at the determination of approximal carious lesion depths compared with Ultraspeed. Radiographs of 80 extracted human molars and premolars were taken with both films under standardized conditions. The presence or absence of caries and depth of lesions was determined by three observers using a predetermined scale. The actual status of each surface was determined histologically. Observer responses were assessed with the Gamma measure of association test. Differences between the observers' agreement levels were not significant. The efficiency of Insight and Ultraspeed at true depth diagnosis was found to be 54.9%; 55.8% and Gamma values were found to be 0.883 and 0.922, respectively, at p<0.001. The difference between the two films was not statistically significant (p=0.852). This study suggested that there was no statistically significant difference between the two films at detecting the depths of approximal carious lesions.
