Abstract
A mesiodens is a supernumerary tooth located in the premaxilla between the two central incisors. Although various complications attributed to mesiodens have been reported, oronasal fistula are rare. We encountered a 62-year-old male patient with a complaint of leakage of water into the nose over the past 1 year. A small fistula was observed in the middle of the hard palate. Computed tomography revealed two inverted impacted mesiodens with osteolytic changes extending from the oral cavity to the nasopalatine canal; thus, we diagnosed the patient with an oronasal fistula attributed to infection of the mesiodens. The two mesiodens were extracted under general anaesthesia and closure of the fistula was performed. No recurrence was observed at the 1 year follow up.
