Ectopic tooth in maxillary sinus: Case series

Shandilya Ramanojam et al. Ann Maxillofac Surg. 2013 Jan.

Abstract

Ectopic eruption of a tooth within the dentate region of the jaws is often noticed in clinical practice and is well documented in the literature. But the ectopic eruption into the non dentate region is rare and scantly documented. The maxillary sinus is one such a non dentate region, apart from nasal septum, mandibular condyle, coronoid process and the palate, to accommodate such ectopic eruptions of teeth. Due to its rarity and lack of consensus over its management, the incidence deserves to be added to the literature and discussed. Early surgical intervention for removal of ectopic tooth along with enucleation of the associated cyst, if any, is the treatment of choice.

Keywords: Antral tooth; dentigerous cyst; ectopic tooth; maxillary antrum; tooth in sinus.
