Validation of a specific selection criterion for dental periapical radiography.
It has been recommended that the prescription of dental radiographic examinations be based on a series of selection criteria. This study evaluated the usefulness of the presence of a large or deep restoration as an indicator for the need for a radiographic examination. Patients in need of routine examinations were questioned regarding pain in restored teeth. The radiographs of 2269 restored tee...
متن کاملExtraoral periapical radiography: an alternative approach to intraoral periapical radiography
It is difficult to take intraoral radiographs in some patients who are intolerable to place the film in their mouth. For these patients, Newman and Friedman recommended a new technique of extraoral film placement. Here we report various cases that diagnostic imaging was performed in patients using the extraoral periapical technique. This technique was used to obtain the radiographs for the pati...

METHODOLOGY A total of 86 subjects were examined. All participants underwent a full-mouth radiographic survey (14 periapical radiographs) and a panoramic radiography. The periapical status,...
متن کاملExtraoral Periapical Radiography: A Technique Unveiled
Introduction: Extraoral periapical radiography (EOPAR) is a technique where the film is placed extraorally overlying the tooth of interest and the X-ray beam is directed from the opposite side of the face. This technique was first proposed by Newman and Friedman (2003) and later modified by Chia-Hui Chen et al (2007) to assist certain patient populations who are unable to tolerate intraoral fil...
متن کاملRemoving Distortion of Periapical Radiographs in Dental Digital Radiography Using Embedded Markers in an External frame
To carry out in vivo and in vitro comparative pilot study to evaluate the preciseness of a newly proposed digital dental radiography setup. This setup was based on markers placed on an external frame to eliminate the measurement errors due to incorrect geometry in relative positioning of cone, teeth and the sensor. Five patients with previous panoramic images were selected to undergo the propos...
