A clinical analysis of 15 patients with foreign bodies of dental origin in the air and food passages treated in our department during the 7 years from 1984 to 1990 is described.<BR>The foreign bodies were present in the alimentary canal in 14 patients and in the airway in one patient at the time of the initial examination. The age of the patients ranged from 6 to 83 years and there was a slight predominance in females with a male to female ratio of 2 to 3. The foreign bodies consisted of 3 inlays, 2 crown bridges, 2 onlays, 2 postcrowns, 1 denture, 1 reamer, 1 metal crown, 1 resin temporary crown, 1 conus inner crown and 1 amalgam filling. The accidental swallowing and aspiration occurred during fitting in 7 patients and dental extraction in 2 patients. The accident occurred while eating in 2 other patients. The foreign bodies were removed by endoscopic or bronchoscopic procedures on the day of the accident in 2 patients. Spontaneous evacuation in the stool occurred within 3 days in 9 patients. The fate of the foreign bodies was unknown in the 4 other patients. Serious complications resulting from the accidental swallowing or aspiration were not encountered in any patients.
