We treated 109 cases of foreign bodies of dental origin in the airway and gastrointestinal tract in our hospital during the 8 years from 1987 to 1994. A statistical analysis was performed on 109 cases, and the results were as follows:<br>1. Of the 109 cases, 60 were males and 49 were females; 71 patients (65.1%) were over 40 years old.<br>2. Eleven cases involved foreign bodies in the airway and 98 cases involved foreign bodies in the gastrointestinal tract.<br>3. In both the airway and the gastrointestinal tract, crown restorations were the most common foreign objects, followed by dental instruments.<br>4. Gastrointestinal foreign bodies were ejected by defecation in all but 2 cases. In cases of spontaneous ejection, ejection occured within 4 days after misswallowing in 81.2% of patients.<br>5. The accidents occured during dental treatment in 92 cases (84.4%) and while eating in 17 cases (15.6%).<br>We stress the importance of making models of dentures and crown restorations that are misswallowed before removal.
