ABSTRACT

Dentigerous cysts are benign odontogenic cysts that are associated often with the crowns of permanent teeth. The aim of this paper is to help practitioners in the diagnosis, treatment and follow-up of a child with a dentigerous cyst, and to show the possibility of dental replantation after ablation of the cystic lesion. A ten-year-old boy was referred to our department of oral surgery with a diagnosis of dentigerous cyst involving maxillary right first premolar. Cyst enucleation was carried out with extraction of the involved tooth. Then, the premolar was immediately replanted into the cystic cavity. At the radiographic follow-up at 12 months, no recurrence was detected. After eight year follow up period the tooth was fully erupted and in perfect occlusion with positive response to the vitality test. Dental X-ray showed a lamina dura with root development. Cyst enucleation, extraction of involved tooth and immediate replantation might be considered as a viable treatment to obtain healing of the lesion, spontaneous eruption of the tooth and physiological restoration of bone.
