Lateral dentigerous cyst associated with mandibular 2nd molar: an unusual entity

Dentigerous cysts are generally associated with the crowns of impacted or unerupted permanent teeth and are more common in the third and fourth decades of life. Most dentigerous cysts are mainly developmental in origin but may not be similar for all cases. The purpose of this paper is to present a case of lateral dentigerous cyst with unusual presentation in a 14 year old boy and discuss the variation in etiology, presentation of such a cyst and in its management.
