title: A case of an inverted tooth in the nasal cavity.
abstract: We report a case of an inverted tooth in the nasal cavity. The patient was a 27-year-old man who attended our hospital in May 1998, complaining of left cheek-pain. There was nothing remarkable in his medical or family history. Fiberscopic (intranasal) and radiological examinations revealed a white foreign body in the left nasal cavity, within 2 cm of the left nostril. This foreign body was diagnosed as an inverted tooth. It was removed under general anesthesia and found to be 17 mm in length. Although the tooth showed a single root, it possessed two cusps and we deduced it to be a molar.
