For which condition is a dentigerous cyst commonly associated?

A dentigerous cyst is commonly associated with an impacted third molar. This type of cyst typically forms around the crown of an unerupted tooth, most often the wisdom teeth, which are the third molars. The cyst arises from the accumulation of fluid between the reduced enamel epithelium and the crown of the tooth, leading to the cystic formation.

The link between dentigerous cysts and impacted third molars is significant because this location is where these cysts are most frequently identified in dental practice. As the third molar is often impacted due to insufficient space in the dental arch, it creates an environment that predisposes to the development of a dentigerous cyst.

While the other conditions listed may relate to dental issues, they are not the primary associations with dentigerous cysts. Supernumerary teeth can sometimes lead to cyst formation, but it is less common than with impacted third molars. Dental trauma and periodontal abscesses do not typically involve the development of dentigerous cysts in the same way.
