Radiographic examination is an indispensable adjunct in endodontics, especially for diagnosis, treatment, and follow-up after endodontic therapy. Currently, periapical radiography is the first choice of imaging method in endodontics clinical practice and a valuable tool to diagnose and to follow-up patients. Furthermore, the practice of radiography is traditionally used in various stages of root canal therapy, such as for determination of work length. Digital intraoral radiography systems are being used increasingly for these purposes, with having similar accuracy as film radiography. Currently, a variety of digital intraoral systems are commercially available.
