Teeth in Rare Locations with Rare Complications: An Overview.

Ectopic presence of teeth within the dentate region is common in clinical practice. However, the presence of teeth in non-dentate areas such as the nasal cavity or the maxillary sinus is rare. These may remain asymptomatic for years, may be misdiagnosed as foreign bodies, or may present with some serious complications involving the nose and paranasal sinuses. Complications such as nasal obstruction, epistaxis, headaches, rhinolith formation, epiphora, sinusitis and oro-antral fistula have been well described in literature, however, very few cases of antro-cutaneous fistulas have been reported. We discuss three cases of ectopic eruptions of teeth, all occurring in children. The clinical and radiographic findings of the cases, possible etiology, complication, diagnosis and treatment are discussed.
