title: Evaluation of image quality in individual films of double film packets.
abstract: A total of 47 double film packets were exposed of a radiographic standard (step-wedge), a clinical model (dried skull), and a clinical situation (endodontic therapy). Dentists were employed as expert observers to compare detail and definition between front and back films within each packet. Front films (those closest to the source) had significantly superior image quality compared to back films (those further from the source). In vitro radiographic trials were significantly similar to in vivo radiographic results.
