the patient. Had a single crown been ingested, it could have been allowed to pass through the intestines and could have been retrieved by examination of the feces to ensure that it had actually passed. Although the ingested fixed partial denture in our case may have passed through the intestines, the most prudent course of action was to retrieve it with endoscopy since it is possible that it could have caused an obstruction or even a perforation due to its relatively large size compared to a single crown. In summary, this is the first report of an ingested

Accidental ingestion and pulmonary aspiration of dental materials are among some of the most common adverse events occurring during dental treatment. According to a study completed by Susini et al 1 that quantified the frequency and type of ingested or aspirated dental materials, 29% were found to be dental prostheses, 27% were burs, and 2.2% were endodontic files. These statistics reinforce the importance of using airway protection (eg, a throat pack or screen) when performing a dental procedure. Currently, the gold standard for treating

Anteroposterior Radiograph After Passing the Amalgam Fragment

Anteroposterior radiograph obtained approximately 4 hours after the initial anteroposterior radiograph showing the amalgam fragment no longer present and presumed to have passed into the stomach.

Lateral Radiograph After Passing the Amalgam Fragment

Lateral radiograph obtained approximately 4 hours after the initial lateral radiograph. The amalgam fragment is no longer present and presumed to have passed into the stomach. Extracorporeal radiopacities represent hospital gown buttons (green arrowheads).

Initial Anteroposterior Radiograph Containing an Amalgam Fragment

Anteroposterior radiograph obtained upon patient's arrival at the emergency department. The amalgam fragment was located lateral to the midline at the level of C6.

Lateral Radiograph With an Outline of the Esophagus and a Potential Zenker's Diverticulum

The esophagus and likely position of the Zenker's diverticulum on the lateral radiograph have been outlined in red. This outline has been provided to explain the lateral positioning of the amalgam fragment seen in Figure 1.
