Successful Preservation of a Developing Unerupted Tooth Associated With Dentigerous Cyst in a Child: A Case Report.

Dentigerous cysts (DCs) are odontogenic cysts typically associated with the crowns of unerupted or impacted teeth and are usually discovered when they reach large sizes or get infected. Although common in adults, their occurrence in children are rare. Most cases in children are incidentally discovered on routine radiographic examination of infected deciduous molars. Treatment methods vary based on the size and extend of the lesion, with enucleation and marsupialization being the commonly employed approaches. Despite the variation in techniques, the overall prognosis and treatment outcomes are generally favorable. This case report describes the successful conservative management of a mandibular DC in an 8-year-old female through marsupialization in conjunction with a custom-made acrylic obturator.
