Radiographs determined the presence of a crown with a post in the gastric lumen (Figure 4).
Supine abdominal anteroposterior radiographs. At presentation (a), a linear opaque right upper quadrant object, a dental bit (arrow), was presumed to be within the pre-pyloric region of the stomach or in the first portion of the duodenum. A follow-up radiograph performed on the same date (b) demonstrated migration to the pelvis.

An initial abdominal radiograph revealed a linear radiopaque object in the right upper quadrant (Figure 5).

Supine anteroposterior (a) and coned-down lateral (b) abdominal radiographs. A tooth (arrows in a, b), most likely a maxillary canine, is located in the descending colon. There is a normal bowel gas pattern.

The abdominal radiographs (Figure 6) showed the presence of a tooth in the descending colon and no evidence of bowel perforation. It may become obscured by the overlying skeleton (Figure 6b), which necessitates the acquisition of biplane radiographs for initial evaluation of the ingested foreign bodies.

Anteroposterior (a) and lateral (b) neck soft tissue radiographs show a denture (arrows) in the hypopharynx. Mild distension of the pharynx with air, more apparent on the lateral view (b), is likely secondary to mass effect of the foreign body on the larynx.

The denture was lodged in the hypopharynx and discovered on soft tissue neck radiographs (Figure 7).
Portable anteroposterior chest radiograph shows pneumomediastinum (arrows) and soft tissue emphysema at the base of the neck (arrowhead). A denture lodged in the oesophagus is obscured by the overlying soft tissues and technique.

Chest radiograph findings of pneumomediastinum and cervical soft tissue emphysema were concerning for oesophageal perforation by the ingested denture (Figure 8).
Multiple spot images obtained during fluoroscopic oesophagography. An early image (a) reveals a denture (white arrowheads) within the oesophageal lumen outlined by the oral contrast. The extraluminal oral contrast in the mediastinum (straight white arrow) and the left pleural space (black arrowheads) is noteworthy. During the course of the study (b), the denture (white arrowheads) turned horizontally and began to protrude through the oesophageal rent. One of the final images (c) demonstrates further extraluminal migration of the denture (white arrowheads). Oral contrast outlines the cephalad margin of the midthoracic oesophageal tear (black arrow) communicating with the mediastinal contrast collection (straight white arrow). Oral contrast transit into the stomach is evident (curved white arrow).

Subsequent fluoroscopic oesophagography with water-soluble contrast revealed thoracic oesophageal tear with extraluminal contrast accumulation in the mediastinum and left pleural space (Figure 9).
