Abstract
Dentigerous cyst is normally associated with crown of an unerupted or developing tooth and is one of the most common odontogenic cyst. It is more commonly seen in association with mandibular third molar and maxillary canine. Dentigerous cyst generally occurs in second or third decades of life. Its association with incisors are rare entity. Dentigerous cyst usually includes a tooth which can not complete the eruption process and involves the crown by the fluid accumulation in between the layers of enamel organ. The treatment modalities for dentigerous cyst are marsupialization or enucleation and depends upon the involved structures. Here we report a case of dentigerous cyst associated with permanent mandibular lateral incisor. It was enucleated along with the lingually erupted lateral incisor. There was no recurrence observed after one year follow up. Keywords: Dentigerous cyst, Odontogenic cyst, Lateral incisor, Marsupialization, Enucleation.
Highlights
Dentigerous cyst is commonest developmental odontogenic cyst and has a incidence rate between 20% and 24% among all the jaw cysts.[1]
Dentigerous cyst are of two types: developmental and inflammatory
Developmental type is derived from reduced enamel epithelium, by accumulation of fluid between reduced enamel epithelium and enamel
Summary
Dentigerous cyst is commonest developmental odontogenic cyst and has a incidence rate between 20% and 24% among all the jaw cysts.[1] It is associated with the crowns of unerupted tooth or developing tooth bud, and is normally attached to the cervical margins of affected tooth. 2 permanent third molars are generally associated with this cyst but association with mandibular incisors are rarely seen. 3. Dentigerous cyst are of two types: developmental and inflammatory. Developmental type is derived from reduced enamel epithelium, by accumulation of fluid between reduced enamel epithelium and enamel. Inflammatory type is developed, as a result from periapical infection in its Predecessor deciduous tooth, which spread upto permanent. 4 Dentigerous cysts are always associated with a missing tooth or failure of tooth eruption, and may be asymptomatic until they become enlarged enough.
