A case of accidental ingestion of a partial denture base removed by upper gastrointestinal endoscopy

Summary.The majority of accidental ingestions and aspirations of dental foreign bodies occur during dental treatment.However,most of them are naturally excreted without any problem although the time to excretion varies.Among dental foreign bodies,removable partial dentures involve the risk of causing perforation of the digestive tract due to the morphology of the clasp;therefore,improper treatment or measures may cause serious complications.Now,there are increasing opportunities to proactively use an endoscope to remove foreignsubstances from the gastrointestinal tract.We report a case of accidental ingestion of a removable partial denture,extracted by upper gastrointestinal endoscopy.It is important to remove blunt foreign substances by endoscopy at an early stage.Simultaneously,it is imperative to enhance cooperation between dentistry and medicine and take appropriate measures
