Image quality enhancement in digital panoramic radiograph
One of the most common positioning errors in panoramic radiography is palatoglossal air space above the apices of the root of maxillary teeth. It causes a radiolucency obscuring the apices of maxillary teeth. In the case of this positioning error, the imaging should be repeated. This causes the patient be exposed to radiation again. To avoid the repetition of exposing harmful X-rays to the pati...
متن کاملDental Radiograph Interpretation
Interpreting dental radiographs can be daunting, but it is very similar to interpreting a standard boney radiograph. The major difference is that dental radiographic changes are often more subtle. In addition, there are pathologic states that are unique to the oral cavity. Finally, there are several normal anatomic structures that may mimic pathologic changes. This lecture concentrates on the m...
متن کاملFirst Dental Radiograph (1896)
In 1895, the German physicist, Wilhelm Conrad Röntgen (1845-1923), who was 50 years old by then, studied cathode rays with Crookes tubes. He was more precisely concerned with the penetration of the rays through the glass. At the time, it had already been established that cathode rays could pass through the tube wall and penetrate a few centimetres in the air. In the evening of November 8, durin...
متن کاملDiagnostic Reference Level Arising from Dental Panoramic Radiography
Introduction The present work describes a study in which, based on patient dose measurements, thermoluminescent dosimeters were used to obtain the diagnostic reference level arising from panoramic radiography. Materials and Methods Ten panoramic units and a sample of 15 patients per X-ray unit were studied. Two thermoluminescent dosimeter chips were placed on the skin surface of selected organs...
