Abstract:
Ingestion or aspiration of foreign objects may present as a significant complication with various common dental procedures. The most reported ingested or aspirated dental materials have included endodontic instruments and metal restorative and prosthetic materials, which can often be identified clinically and radiographically from their relative radiodensities. The authors present an unusual report of lodged impression material in the hypopharynx, which was not detectable radiographically.
