Abstract 

Dentigerous cyst is the most common developmental odontogenic cyst of the jaws. They are frequently associated with impacted mandibular third molars and the maxillary canines. Association of ectopic tooth in the maxillary sinus with dentigerous cyst is quite uncommon. We report a case of dentigerous cyst associated with ectopic tooth at the roof of the maxillary sinus manifesting as a unilateral facial swelling with encroachment into the nose and orbit. This article addresses its unusual location, the important aspect of its etiopathologenesis, its clinical characteristics, differential diagnosis and management.

Key words: Dentigerous cyst, ectopic tooth, maxillary sinus, unilateral facial swelling, benign tumors.
