Two dental x-ray films compared for rater preference using endodontic views.
Four groups of patients were selected during various phases of endodontic therapy to receive two comparable radiographic exposures. One exposure was made with Kodak Ultraspeed dental x-ray film and the second exposure was made with Kodak Ektaspeed dental x-ray film. The films were coded and mounted in a side-by-side format to be judged by thirty raters. A double-blind clinical protocol was followed. Ultraspeed film was judged superior to Ektaspeed film in terms of contrast, image quality and rater satisfaction.
