Adjacent dentigerous cysts with the ectopic displacement of a third mandibular molar and supernumerary (forth) molar: a rare occurrence.

Dentigerous cysts are the most common odontological cysts of the jaws, being associated with the crowns of permanent teeth, especially unerupted mandibular third molars. Multiple dentigerous cysts are rare and most often occur in association with a developmental syndrome. This article presents an unusual case of nonsyndromic adjacent dentigerous cysts associated with a mandibular third molar and a supernumerary molar. This occurrence has not been previously reported.
