Ectopic Third Molar Associated With Dentigerous Cyst in Maxillary Sinus: A Case Report

Abstract

Dental development is an interactive event between the oral epithelium and mesenchymal tissue. Any abnormal interaction at any step may result in ectopic teeth development.Teeth that are ectopically developed in non- dental areas has been reported in the nasal cavity, nasal septum, chin and maxillary sinus. Ectopic teeth in the maxillary sinus are asymptomatic in most cases;however it may precipitate sinusitis or sometimes result in ophthalmic symptoms.We report a case of ectopic maxillary third molar inthe right maxillary sinus with a non-specific symptoms which was enucleated out with the surrounding dentigerous cyst via a Caldwell-Luc procedure.
