Dentigerous Cyst in the Children: A Case Report

Introduction: Dentigerous cysts are the second most common developmental odontogenic cysts of the jaw, arising from impacted, embedded or unerupted permanent teeth. They apparently develop by accumulation of fluid between the reduced enamel epithelium and the tooth crown of an unerupted tooth. There is usually no pain or discomfort associated with the cyst unless there is an acute inflammatory exacerbation. Case Presentation: The purpose of this case report is to present a case of a dentigerous cyst with an unusual presentation in a 6-year-old child came with the swelling over right back region of the jaw which was asymptomatic appearing bony hard on palpation. Radiography showing unilocular radiolucency with an unerupted mandibular tooth crown is seen. Histology revealed H & E-stained section showing non keratinized epithelium 2-3 cell layer thick underlying connective tissue wall is loose fibrocellular with mild to moderate inflammatory cells infiltrate comprising of plasma cells, lymphocytes & numerous blood vessels and the definitive diagnosis of Dentigerous cyst was made. Management is done using enucleation of the cystic space with curettage & extraction of associated teeth. Conclusion: Management of odontogenic lesions, such as dentigerous cysts in children, presents an unparalleled challenge to general and pediatric dentists alike. A thorough understanding of the nature of the lesion backed by good clinical history and state-of-art radiography can go a long way in helping the clinician to arrive at the correct therapeutic choice of approach, ameliorate the condition in the best long-term interests of the young patient.
