Bilateral dentigerous cyst associated with polymorphism in chromosome 1qh+.

Non-syndromal bilateral dentigerous cysts are rare. It is conceivable that they are either under-recognized or under-reported. In this article we report the unusual occurrence of non-syndromic bilateral dentigerous cysts associated with mandibular third molars with polymorphism in chromosome 1qh+. It is suggested that in non syndromal cases of bilateral dentigerous cysts karyotyping should be done to confirm the association with chromosomal 1 anomaly.
