OBJECTIVES The diagnosis of root fractures by conventional radiographs is still difficult because of limitations of 2D images. Cone-beam volumetric tomography improves the diagnosis capacity in dentistry, such as increased radiation dose to the patient and presence of artifacts on the image. STUDY DESIGN This study compared the images obtained on conventional periapical radiographs and 3D sca...

Objective The aim of this study was to compare the diagnostic performance convolutional neural networks (CNNs) with human observers for detection simulated periapical lesions on radiographs. Study Design Ten sockets were prepared in bovine ribs. Periapical defects 3 sizes sequentially created. radiographs acquired each socket no lesion and size a photostimulable storage phosphor system. Radiogr...

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...

Periapical radiography is essential in diagnosis, treatment planning and follow-up in endodontics. However, image interpretation can be confounded by geometric distortion, superimposition of regional anatomy and technique errors. These problems can be overcome by utilizing small or limited-volume cone beamcomputed tomography imaging techniques, which produce accurate 3-D images of the teeth and...

OBJECTIVES To evaluate the accuracy of using routine 2-dimensional (2D) radiographs (panoramic and periapical) when evaluating the position of orthodontic temporary anchorage devices (mini-implants) in the maxilla, and to compare the results to 3-dimensional cone-beam computed tomography (CBCT). METHODS This cross-sectional study was conducted at King Abdulaziz University, Faculty of Dentistr...

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...

PURPOSE In the present study, we coined the term 'alveolar dome' and aimed to demonstrate the prevalence of alveolar domes through digital periapical radiographs. MATERIALS AND METHODS This study examined 800 digital periapical radiographs in regard to the presence of alveolar domes. The periapical radiographs were acquired by a digital system using a photostimulable phosphor (PSP) plate. The...

OBJECTIVE The aim of this study was to analyze the prevalence of AP in relation to the quality of endodontic treatment in an Italian adult population. METHODS We examined panoramic radiographs (OPG) of 384 patients aged between 18 and 60 years who came under observation for a first dental examination. Two experienced examiners assessed the radiographs according to standardized criteria by exa...

BACKGROUND This study aimed to evaluate the accuracy of two imaging methods in detecting the apical pathology in endodontically treated teeth. MATERIAL AND METHODS A clinical examination from a sample of 156 teeth of patients treated by students of masters in endodontics at the Care Center of the Faculty of Dentistry at St. Joseph University, Beirut was done after 5 years of follow-up. Perira...
