Objectives: To assess and compare five diagnostic imaging methods used in the identification of periapical diseases, of different diameters, mechanically simulated. Methods: The sample of the present study consisted of 12 dried human mandibles. Digital panoramic radiography, conventional and digital periapical radiography (charged couple device and photo-stimulable phosphor plate), and high-res...
This study investigated the accuracy of diagnosing periapical lesions through conventional radiography (CR) and direct digital radiography (DDR) technique. A total of 170 patients with clinically suspected periapical pathosis and 30 normal subjects were included in the study. Both the conventional and digital images were taken with same exposure parameters keeping the film without lead foil and...
conclusions based on 8.2 mm cut-off point could differentiate 83% periapical granulomas and 79% radicular cysts from radiography images. background the distinction between radicular cysts and apical granulomas is important in treatment decision. objectives the current study aimed to differentiate these two lesions based on radiography images. results average size of radiography in periapical gr...
Background and Aims: Dental diagnosis may be affected by the occurrence of the errors in the intra-oral radiographic images and the patients’ treatment plan can be problematic in these cases. The repetition of these radiographs increases the risks of radiation exposure for the patients in turn. The present study assessed the incidences of common periapical radiographic errors taken by dental st...
Objectives: This review article is aimed to determine the accuracy of extraoral periapical radiography as a determinant working length in endodontic treatment and advantages disadvantages this technique.
 Review: Endodontic dental for damages reaching pulp which aims maintain tooth. One way succeed an accurate length. The can be determined by intraoral examination but some people are sensi...
AIM To compare the diagnostic accuracy of intraoral digital periapical radiography with that of cone beam computed tomography (CBCT) for the detection of artificial periapical bone defects in dry human jaws. METHODOLOGY Small and large artificial periapical lesions were prepared in the periapical region of the distal root of six molar teeth in human mandibles. Scans and radiographs were taken...
Introduction Dental implant placement in the region of the mental foramen has been known to cause neurosensory deficit due to nerve injury.1-4 The identification and preservation of the anterior loop (AL) of the mental nerve is an important means of avoiding such neurosensory deficit.5-7 There is a general consensus that plain film radiographs are inadequate for the accurate identification of t...
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...
