Infected dentigerous cyst in maxillary antrum mimicking maxillary sinusitis

Abstract

Cyst is defined as a pathological cavity which may or may not be lined by an epithelium and is usually filled with solid, semisolid or gaseous material. Dentigerous cyst is of odontogenic origin and is usually associated with an impacted tooth. Dentigerous cyst in maxillary antrum is often misdiagnosed in peripheral health care centers due to initial complaints mimicking maxillary sinusitis with patients reporting to general physicians/otolaryngologist for treatment. This article intends to report a case of infected dentigerous cyst initially managed as recurrent maxillary sinusitis in a peripheral rural health care center in high altitude region with limited health care facilities.
