Infl ammatory Dentigerous Cyst Arising from a Non- Vital Primary Tooth and Associated with a Developing Premolar: A Pediatric Case Report

A dentigerous cyst is a type of odontogenic cyst that typically develops in individuals in their first and second decade. It is characterized by its association with an unerupted tooth and forms around the crown due to fluid accumulation between the layers of the enamel organ, preventing normal tooth eruption. Although rare, dentigerous cysts can occur during the first decade of life, often developing in an immature permanent tooth as a result of chronic inflammation from an overlying non-vital primary tooth. This report presents a case of a dentigerous cyst in the primary dentition of a 7-year-old child. The cyst was completely enucleated, and the unerupted permanent first premolar was extracted from the primary mandibular right premolar region. No recurrence was observed during an 18-month follow-up period. Key Words: Children, Dentigerous cyst, Developing premolar
