Ghost artifacts on panoramic radiographs

Dental panoramic radiographs (DPTs) are used to diagnose caries, periodontal disease, trauma, pathologic conditions in the jaws, supernumerary teeth, and orthodontic needs. Digital imaging has been an improvement in terms of exposing patients to less radiation. Panoramic radiographs use an intensifying screen that is removed for digital panoramic radiographs. Panoramic radiographs involve a moving x-ray source and detector plate that will ideally display only the objects in the focal trough. However, they suffer from ghost artifacts that can limit their effectiveness and complicate interpretation.
