RESULTS: Twenty-eight of the 42 teeth were proved intraoperatively to be fractured. The sensitivity and specificity averaged for the two reviewers in the assessment of vertical fractures were 23% and 70%, respectively, with dental radiography and 100% and 100%, respectively, with CT. Consensus reading showed sensitivities of 25% for dental radiography and 75% for CT. Eight (reviewer A) or nine ...
AIM To investigate the quality of periapical radiographic images produced by two digital dental radiography systems, a charge-coupled device (CCD) and a photostimulable phosphor (PSP) image plate system, and to examine the overall radiation exposure when using these systems in a clinical setting. METHODOLOGY Patients were randomly allocated to both systems and the resultant radiographs rated ...
nowadays, radiography is a necessary procedure in diagnosis and treatment of patients with dental problems. according to the alara (as low as reasonably achievable) principle, dentists must take radiographs of sufficient quality at the lowest possible radiation dose to the patients. the assessment of patient dose on panoramic radiography is difficult because of dynamic nature of the imaging pro...
Background: Currently, dental implant is one of the most modern approaches to teeth replacement. Panoramic radiography is considered as the prerequisite for implant therapy. The purpose of the present study was to investigate the vertical magnification of digital panoramic images in various anatomic parts of the mandible. Method: A total of 30 patients referred to Sajjad Radiography Center for...
