title: Two dental x-ray films compared for rater preference using endodontic views.
abstract: 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.
