Abstract: Dentigerous cysts are one type of odontogenic cyst originating from unerupted tooth follicles and are the second most common type of cyst after radicular cysts. These lesions are generally asymptomatic, but in children they can cause permanent tooth eruption disorders. This case report discusses the management of a dentigerous cyst associated with permanent central incisor impaction in a child. A 9-year-old boy came with his parent, complaining that his upper left front tooth had not grown in. Intraoral examination revealed persistence of deciduous tooth 62 and failure of permanent tooth 21 to erupt. Panoramic radiographic examination showed a well-defined radiolucent area surrounding the crown of impacted tooth 21. CBCT examination revealed a dentigerous cyst measuring approximately 11.9 mm x 9.6 mm. The treatment involved enucleation of the dentigerous cyst and observation for the eruption process of tooth 21. At six months postoperatively, tooth 21 had not erupted into the occlusal plane, necessitating further orthodontic intervention to facilitate eruption. The prognosis for tooth 21 remains favorable with continued follow-up and adjunctive orthodontic therapy. In conclusion, dentigerous cysts should be recognized as a potential cause of permanent-tooth eruption failure.
