title: Radiographic and electronic diagnostic systems.
abstract: Radiography forms the basis for determining the length of tooth in endodontic therapy. Radiographs can be manipulated by digital image processing, which can improve their diagnostic quality as well as enable the images to be stored electronically. Electronic apex locators, when used in conjunction with radiographs and electronic imaging systems, become useful adjuncts in endodontic treatment. They provide the clinician with the ability to accurately determine the length of tooth, thus making apex locators an important component in endodontic therapy.
