Reviewing the literatures, the most frequently impacted tooth was mandibular third molar, followed by the maxillary third molars, the maxillary canines and the mandibular premolars. The current case report aimed to present a rare inverted and impacted maxillary third molar incidentally detected in a patient of mandibular unicystic ameloblastoma on panoramic radiography, highlighting the importa...

OBJECTIVES To report radiographic findings of examinations with computed tomography (CT) of impacted lower third molars with an intimate relation to the mandibular canal and to investigate how findings of a dark band across the roots of the lower third molar on panoramic views correspond to the CT findings. METHODS CT images of 90 lower third molars (64 patients, mean age 34.6 years) in which...

PURPOSE This study was performed to investigate the course of the mandibular canal on panoramic radiography and the visibility of this canal on both panoramic radiography and cone-beam computed tomography (CBCT). MATERIALS AND METHODS The study consisted of panoramic radiographs and CBCT images from 262 patients. The course of the mandibular canal, as seen in panoramic radiographs, was classi...

An extradural catheter was inserted at the third lumbar interspace for relief of pain during labour in a 21-year-old gravid patient. Attempts to withdraw the catheter met with resistance and produced severe pain in the distribution of the second left lumbar nerve. Radiography revealed an acutely angled loop of the catheter over the L2-3 nerve root.

conclusions however, root and canal anatomies of third molar teeth are unknown, but studies focusing on third molar teeth have shown their possibility of treatment. results according to the study on 173 mandibular third molars, 92.4%, 4.6%, and 2.89% had two, one, and three roots, respectively. majority of them had two or three canals and most of mesial root canals were type 2; but in 179 maxil...

background: designing and shielding of an appropriate radiography room has been one of the major concerns of radiation scientists since the first decade after the invention of x-rays. recently, report no.147 of national council on radiation protection and measurements (ncrp) has been published. in this study the researchers have investigated the effect of new report recommendation on primary an...

BACKGROUND Lodox-Statscan is a whole-body, skeletal and soft-tissue, low-dose X-ray scanner Anterior-posterior and lateral thoraco-abdominal studies are obtained in 3-5 minutes with only about one-third of the radiation required for conventional radiography. Since its approval by the Food and Drug Administration (FDA) in the USA, several trauma centers have incorporated this technology into the...
