A Case of Supernumerary Tooth within Fungus Ball in the Maxillary Sinus

Abstract

The ectopic eruption of a supernumerary tooth can occur in the sinonasal area, but due to its rarity, few cases of ectopic tooth eruption in the maxillary sinus have been reported. A fungus ball in the paranasal sinuses usually involves just one sinus, most frequently the maxillary sinus. Here, the authors present a case of an ectopic supernumerary tooth embedded in a fungus ball of the maxillary sinus.
