It has been used since 1970 in medical field and has entered dentistry in 1980 after some modifications. In this technique, x-ray is used with no need to developing and fixing radiographs, negatoscope and dark rooms. A selenium sheet is used in this method that is constantly charged electrostatically. A special powder called toner is used for developing process. In order to have a permanent cliché, a photograph is made from the image.
