There is slight horizontal overlap between the maxillary premolars. Correct horizontal angulation, direct the PID more toward the distal. With film bending, images appear stretched and distorted. There will be more coverage of maxillary teeth and fewer mandibular teeth. The overlapping is more excessive toward the mesial of the film than the distal of the film. Placing the receptor more lingual to the teeth where the palate and floor are deeper will make positioning easier and more comfortable for the patient. A thin radiolucent line appears on the film with film creasing. Match each letter with its proper sequence number. Radiopaque artifacts or radiolucent scratch marks on the image indicate which of the following? What can you do to prevent this problem from occurring? position the image receptor parallel to the long axis of the tooth. (1). Which one is the EXCEPTION? Patient movement causes a blurred image. (4). This X-ray beam was angled too much to the distal. This error occurs due to the rectangular collimator being seated improperly in the indentations of the aiming ring. Intraoral Imaging: Basic Principles, Techniques and Error Correction. Placement errors will be discussed first as they are the most common of all errors. The film was exposed in the patient's mouth twice. (2). Match each letter with its proper sequence number. DEN 112 practice final exam 1 - when preparing a paent - Studocu dr. shelly peyton has asked you to take a panoramic radiograph on a 12-year-old patient of record, (not a new patient). Which one is the EXCEPTION? This is a common problem in small mouths. direct the x-ray beam through the interproximal regions. This causes the embossed pattern on the foil, a herringbone or diamond effect, to appear on the processed film. decrease the vertical angulation of the tubehead. _______________ in the developer solution. FIGURE 5. Double-exposed film causes two images in the radiograph. which of the following areas would appear gray on a radiographic image of correct density? 3. It is acknowledged that the routine performance of radiography is not recommended.
