Digital radiography is a type of X-ray imaging that uses sensors to replace traditional photographic X-ray film, producing enhanced computer images of teeth, gums, and other oral structures and conditions.

Digital dental radiographs can be taken inside (intraoral) or outside (extraoral) the mouth. Intraoral X-rays, are the most commonly taken dental X-ray. They provide great detail and are used to detect cavities, check the status of developing teeth and monitor teeth and bone health. Extraoral X-rays do not provide the detail of
intraoral X-rays and are not used to identify individual tooth problems. However, they are used to detect impacted teeth, monitor jaw growth and development, and identify potential problems between teeth, jaws and tempromandibular joints
(TMJ), or other facial bones.
