Dental radiography chapter 21 terms (Principles and techniques 6th ed)

TermDefinition
Bite-wing image Radiographic image of the crowns of maxillary and mandibular teeth, interproximal areas, and areas of crestal bone on the same image
Interproximal Between two adjacent surfaces
Interproximal examination Intraoral examination used to inspect the crowns of both maxillary and mandibular teeth on a single image.
Bite-wing receptor Type of receptor used in interproximal examination. The bite-wing receptor has a "wing", or tab, and the patient "bites" on the wing to stabilize the receptor
Alveolar bone Bone that supports and encases the roots of teeth
Crestal bone Coronal portion of alveolar bone found between teeth; also known as the alveolar crest
Contact areas The area of a tooth that touches an adjacent tooth; the area where adjacent tooth surfaces contact each other
Horizontal bite-wing The bite-wing receptor is placed in the mouth with the long portion of the receptor in a horizontal direction
Opened contacts On a dental image, opened contacts appear as thin radiolucent lines between adjacent tooth surfaces; no overlapping of teeth in image.
Overlapped contacts The area where the contact area of one tooth is superimposed over the contact area of an adjacent tooth on a dental image
Vertical bite-wing The bite-wing receptor is placed in the mouth with the long portion of the receptor in a vertical direction
Beam alignment device A device used to position an intraoral receptor in the mouth and maintain the receptor in position during the imaging procedure
Angulation The alignment of the central ray of the x-ray beam in both horizontal and vertical planes
Central ray The theoretical center of the primary X-ray beam emitted from the tube
XCP (Extension Cone Paralleling) A standardized instrument system used in dental radiography to ensure that the X-ray beam is perfectly aligned with the X-ray film or digital sensor
