Use of an inclined footrest for panoramic dental radiography.
An inclined footrest was evaluated as a positioning aid for dental panoramic radiography. Experimental and control groups of students were examined by a conventional panoramic technique, with and without the addition of an inclined footrest. All radiographs obtained were evaluated for six parameters in a single-blind fashion by three dentists. Results indicated that the inclined footrest reduced spinal-shadow artifacts and improved over-all image quality.
