Abstract

Supernumerary, ectopic tooth eruption in a non-dental area is a rare entity. The ectopic development of tooth found in non-dental environment has been reported in places such as the nasal cavity, chin, maxillary sinus, mandibular bone, palate and orbital cavity. Ectopic tooth eruptions in the maxillary sinus are usually asymptomatic and are found incidentally during routine clinical or radiological investigations. The diagnosis is usually made by plain-film radiography. Computed tomography is indicated when an ectopic tooth is found prior to surgery. Standard treatment for an ectopic tooth is extraction of the tooth. Here, the authors present a case of supernumerary, ectopic tooth found in the maxillary sinus associated with a mucocele.
