[Case report of bronchial aspiration of metal casting during dental treatment].

Abstract

The authors experienced the bronchial aspiration of metal crown during dental treatment. This article discussed prevention and management of this event. The following conclusions were obtained from this study. 1. The preventive measures such as pharyngeal screen must be used in insertion and removal of metal casting. 2. The patient should be informed of this event before treatment. 3. If prosthesis was disappeared in oral cavity during dental treatment, a dentist must consult the radiologist for diagnostic x-ray taking, even though patient has no symptoms suggestive of aspiration of foreign body. 4. If expulsion of a prosthesis from the airway is not occurred, consultation to the ENT for bronchoscopy should be accompanied.
