Abstract : We experienced a case of accidental ingestion of a root canal instrument. At first, surgical extraction was suggested by a medical doctor, however, the therapeutic strategy was changed upon presentation of a previously published paper. After ingesting fibrous foods, the patient excreted the instrument naturally on the seventh day. The maintenance of guidelines on accidental ingestion would enable treatment policies to be shared with other medical departments.
