Spontaneous regression of bilateral dentigerous cysts: a case report.

UNLABELLED: A dentigerous cyst is the most common developmental odontogenic cyst and believed to be slowly progressive in nature. This case report describes an incidental finding of spontaneous regression of bilateral dentigerous cysts associated with lower impacted third molars in a 30-year-old, fully dentate female. Together with three other similar reports, a few possible explanations are postulated and the understanding of natural history of dentigerous cysts is questioned. CLINICAL RELEVANCE: The discovery of a dentigerous cyst in a patient always warrants special attention. This article highlights the fact that surgical treatment is not the only solution for a dentigerous cyst and, in rare cases, conservative management can save the patient from having unnecessary surgery.
