Dentigerous cyst associated with ectopically impacted maxillary second premolar.

Dentigerous cysts are benign odontogenic cysts that are accompanying with the crown of permanent teeth. They are typically single in incidence and are situated in the mandible. They are usually associated with impacted mandibular third molar and maxillary canines. Here we report a very rare presentation of dentigerous cyst in anterior maxilla accompanying with ectopically impacted maxillary second premolar. The cyst was enucleated along with extraction of premolar.
