Panoramic radiograph
dental radiogram depicting the maxilla, or both maxilla and mandible, on a single film
A panoramic radiograph is a panoramic scanning dental X-ray of the upper and lower jaw. It shows a two-dimensional view of a half-circle from ear to ear. Panoramic radiography is a form of focal plane tomography; thus, images of multiple planes are taken to make up the composite panoramic image, where the maxilla and mandible are in the focal trough and the structures that are superficial and deep to the trough are blurred.
Other nonproprietary names for a panoramic radiograph are dental panoramic radiograph and pantomogram; Abbreviations include PAN, DPR, OPT, and OPG (the latter, based on genericizing a trade name, are often avoided in medical editing).
Types
Dental panoramic radiography equipment consists of a horizontal rotating arm which holds an X-ray source and a moving film mechanism (carrying a film) arranged at opposed extremities. The patient's skull sits between the X-ray generator and the film. The X-ray source is rectangular collimated beam. Also the height of that beam covers the mandibles and the maxilla regions. The arm moves and its movement may be described as a rotation around an instant center which shifts on a dedicated trajectory.
The manufacturers propose different solutions for moving the arm, trying to maintain constant distance between the teeth to the film and generator.
“Panoramic radiograph” enters the record as dental radiogram depicting the maxilla, or both maxilla and mandible, on a single film. Crown Archives preserves that source wording while asking what Panoramic, radiograph and dental can confirm, complicate or overturn.
Why this record matters
“Panoramic radiograph” is worth following because a concise public description often conceals a longer documentary argument. Here, Panoramic, radiograph and dental provides the most credible route into that argument.
Reception evidence should be dated and situated: later canonical status may differ sharply from the work’s initial circulation. The source revision retrieved here is dated Aug 18, 2026. The linked authority identifier is Q743868. None of the 0 selected statements returned an explicit reference.
Rights, attribution and provenance may remain disputed even when a general reference summary presents a stable account. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
