title: Bronchial impaction of an implant screwdriver after accidental aspiration: report of a case and revision of the literature.
abstract: BACKGROUND
  Adverse outcomes resulting from aspiration or ingestion of instruments and materials can occur in any dental procedure. Clinical manifestation depends on the location, the obstructive potential of the foreign body, and the temporal factor since the accidental incident. Accidental inhalation of dental appliances can be an even more serious event than ingestion and must always be treated as an emergency situation.
  
  
  METHODS
  A 62-year-old woman was admitted to our hospital with the suspicion of ingestion of a screwdriver implants. In spite of the clinically asymptomatic presentation, chest radiography in posteroanterior and lateral projections showed a radiopaque dental instrument impacted on the right main inferior bronchus. Rigid bronchoscope was successful to remove the dental instrument under general anesthesia, and the patient was discharged 24 h later.
  
  
  CONCLUSIONS
  Aspiration and ingestion of dental foreign objects are infrequent, but they can occur at large multidisciplinary dental procedures. These episodes have the potential to result in acute medical and life-threatening emergencies since the beginning of the event or at a late stage in proceeding in the underdiagnosed patient. Prevention of such incidents is, therefore, the best approach via the mandatory use of precautions during all dental procedures, and in case of suspicion with no retrievable material, patient must always be submitted to a radiographic study.
