Key Clinical Message: Foreign bodies penetrating from the oral cavity can damage surrounding tissues. This case is considered an extremely rare and fortunate instance in which a maxillary denture appeared to weaken the external force and change the direction of the scissors, preventing damage to vital organs. The patient was a 73‐year‐old man. While on a ladder pruning a plant, he accidentally fell. The gardening scissors passed through the maxillary sinus from the maxillary alveolus and penetrated below the zygomatic arch. At the time of injury, the patient was wearing a metal‐frame denture on the maxilla, and contact between the cutting edge and the denture was speculated to have weakened the piercing force of the blade and changed the direction of the cutting edge. This extremely rare case demonstrates how a maxillary denture could reduce the severity of a penetrating injury caused by scissors. [ABSTRACT FROM AUTHOR]

Key Clinical Message: If a foreign body is seen on chest or abdominal radiographs, accidental aspiration or ingestion of a dental‐related foreign body may be suspected. This report describes a case in which vascular embolization coils seen on radiography were suspected to represent a swallowed dental prosthesis. A 72‐year‐old man with a history of endovascular embolization of portosystemic shunt was admitted for mandibular fracture. On hospital day 2, a foreign body was noted on chest radiographs taken to confirm pleural effusion. No foreign body had been evident on radiographs of the same area the previous day. The foreign body was suspected to be a dental prosthesis, but intraoral examination ruled out this possibility, and the foreign body turned out to be metal coils used to embolize the shunt. Dentists and oral surgeons should be aware that medical devices such as vascular embolization coils can produce images similar to a dental‐related foreign body on chest or abdominal radiographs, and dental‐related foreign body ingestion or aspiration should be considered in the differential diagnosis.
