OBJECTIVE The relationship between mechanical stress and radiographic progression in rheumatoid arthritis (RA) is unclear. The assumption is that mechanical stress is greater in the dominant hand. Therefore, the aim of the present study was to compare the presence and progression of erosions and joint space narrowing (JSN) in the dominant and non-dominant hand. METHODS Data from 194 patients ...
Introduction: Infraorbital ethmoid air cells are such anatomical variations may result sinusitis. CT scan is commonly used for imaging infraorbital ethmoid cells but panoramic radiographs often show infraorbital ethmoid cells. This study aim to determaine the prevalence of infraorbital ethmoid cells on panoramic radiographs in cases older than 4 years referred to Dental School of Islamic Azad U...
Abstract Some craniofacial diseases or anatomical variations are found in radiographic images taken for other purposes. These incidental findings (IFs) can be detected orthodontic patients, as various radiographs required diagnosis. The data of 1020-orthodontic patients were interpreted to evaluate the rates IFs three-dimensional (3D) cone-beam-computed tomography (CBCT) with a large field view...
introduction: the use of panoramic radiography has shown a remarkable expansion over the past 20 years. accurate positioning and preparation of patients is needed to avoid image distortion. the aim of this study was to evaluate the common errors on panoramic radiographs taken in the radiology department of rasht dental school. materials and methods: the study sample included 390 digital panoram...
Posterior wall acetabular fractures that involve 10% to 40% of the posterior wall may or may not require an open reduction and internal fixation. Dynamic stress examination of the acetabular fracture under fluoroscopy has been used as an intraoperative method to assess joint stability. The aim of this study was to demonstrate the value of intraoperative ISO computed tomography (CT) examination ...
