Abstract

Dentigerous cysts (DC) are the most common odontogenic cystic lesions of inflammatory origin occurring in children. They are related to the crown of an unerupted tooth. These cysts are usually asymptomatic and often discovered as an accidental radiographic finding in association with an unerupted tooth. Conventionally they are treated by enucleation of the entire lesion. This article presents a case report where a conservative approach was done via marsupialisation. This conservative surgical technique allows simultaneously the normal eruption of the involved permanent teeth and the ossification of the bony defect. This case report describes management of dentigerous cyst in a 9 year old boy where extraction of 75 was done, followed by marsupialisation procedure where cyst cavity opening was kept patent with the help of an acrylic Obturator.
