A panoramic radiograph shows a small radiopaque ring/loop superimposed over the roots of an endodontically treated maxillary molar (tooth #14). What does this most likely represent?

On panoramic images, metallic objects such as earrings produce a 'ghost image' projected to the opposite side and at a different vertical level; an earring not removed creates a ring-shaped radiopacity overlapping the contralateral structures.Other options: Calcified canals, supernumeraries, and odontomas have characteristic dental morphology, not a free-floating metallic ring.Key exam takeaway: Panoramic ghost images = real radiopaque objects (earrings) projected to the opposite, higher side; remove all jewelry first.
