True about Dentigerous cyst:
Arises in relation to unerupted teeth
It most commonly encroaches maxillary antrum
Mandibular third molar is common site
Common in mandible
Ans. (a) Arises in relation to unerupted teeth, (c) Mandibular third molar is common site, (d) Common in mandible(Ref: Robbins 9th/734; Manipal Surgery 4th/292-93; Harsh mohan 7th/511-12)*Dentigerous cyst is defined as a cyst that originates around the crown of an unerupted tooth and is thought to be the result of fluid accumulation between the developing tooth and the dental follicle.*Radiographically, these are unilocular lesions most often associated with impacted third molar (wisdom) teeth. Histologically, they are lined by a thin layer of stratified squamous epithelium. Often, there is a dense chronic inflammatory cell infiltrate in the connective tissue stroma.*Complete removal of the lesion is curative.
