Dentigerous cyst associated with mandibular lateral incisor-Report of a rare case

The dentigerous cyst is a common type of odontogenic cyst that encloses the crown of an unerupted tooth by way of expansion of its follicle due to the collection of cystic fluid. Reported cases commonly involved the mandibular third molars and maxillary canines. They rarely involve the incisors. The highest incidence of dentigerous cysts occur during the second and third decades. We report a case of dentigerous cyst involving the permanent mandibular lateral incisor which is a rare occurrence. The pathogenesis, clinical and radiological features are discussed.
