AR-SA Xeroradiography is a modern imaging method that
can aid diagnosis of oral, dental and maxillofacial lesions, treatment planning
and follow-ups. 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. The image brightness and contrast
is much better than conventional radiographs while the time of exposure and
developing is less. While in medical fields it is used in extraoral imaging, in
dentistry xeroradiography is used only in intraoral imaging.
