Dear Editor, The selection of appropriate diagnostic techniques is an important step in the treatment of disease. An optimal diagnostic method can provide essential information, while minimizing cost and harm to patients. In dental radiography , attempts have been made to reduce patient exposure to radiation. Cone-beam computed tomography (CBCT) and digital radiography were developed to achieve...

background and aim: clinical and radiographic diagnoses of dental root fractures have always been difficult and require high accuracy in dental care and treatment. the aim of this study was to compare the diagnostic accuracy of intraoral digital radiography (psp) and cbct in the detection of horizontal root fracture (hrf) and vertical root fracture (vrf). materials and methods: for this experim...

BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...

X‐rays were discovered in 1895 by Wilhelm Roentgen. Digital radiology has overtaken conventional screen‐film radiography since it was introduced in the mid‐1980s.[1] Digital imaging uses sensor of solid‐state, and information is presented and stored as an image using a computer. The dawn of the digital era in dental radiography came in 1987 with the first digital radiography system called radio...

Background & Aims: Conventional radiography is used for the diagnosis of problems such as dental caries and failure in root canal therapy. The diagnosis accuracy of conventional radiography is acceptable in the evaluation of anatomical and pathological structures. However, it seems that by using digital radiography we can obtain more information in this field. The aim of this study is to compar...
