Inverted supernumerary nasal tooth

Abstract

The eruption of a tooth into the nasal cavity is a rare and incidental finding during routine clinical or radiological examination. Since the 1960s there were more than 60 reported cases of nasal teeth. To the best of our knowledge, this is only the sixth case report of a supernumerary intranasal canine in the selected period. A 22-year-old male presented with a history of recurrent rhinorrhea, nasal congestion, tension headaches, and insomnia but without previous epistaxis or facial trauma episodes, and with no history of congenital craniofacial malformations. Following a computed tomography examination, a diagnosis of a supernumerary inverted ectopic canine eruption into the left nasal cavity was established. To identify such rarities and prevent possible complications, it is essential to acquire detailed patient history, be familiar with both normal and variant maxillofacial structures, and conduct systematic radiological image analysis
