Dentigerous cyst in the maxillary posterior region associated with an impacted deciduous molar

Abstract

Dentigerous cyst, ranked the second most common developmental odontogenic cyst of the jaws after the radicular cyst, is a well-defined, unilocular radiolucent lesion without symptoms, frequently noted as an incidental finding in routine radiographs. The cystic lining is derived from epithelial remanants of the tooth-forming organ and the teeth most commonly affected are impacted mandibular third molars and permanent maxillary canines. While the dentigerous cyst is not uncommon, its development as a result of an impacted deciduous tooth is rare. The aim of this article was to make a brief literature review and report a case of dentigerous cysts associated with an impacted deciduous molar in the maxillary posterior region, with involvement of the right maxillary sinus.
