摘　　要：BACKGROUND Radicular cyst is a lesion of odontogenic origin that arises from epithelial remains due to periapical periodontitis caused by inflammatory reactions generated at the apex of affected teeth with infected or necrotic pulps.The therapeutic mana gement of radicular cysts is controversial.There is only one case report of enucleation of a radicular cyst managed with microsurgery and apicoectomy,but without the use of the guided tissue regeneration(GTR)technique in the same surgical procedure.The present clinical case describes the management of a radicular cyst with microsurgical approach,performance of an apicoectomy of the tooth associated with the entity,application of GTR technique,use of a resorbable membrane of type I bovine collagen,and bovine xenograft.CASE SUMMARY A 68-year-old patient presented with a radicular cyst from an upper lateral incisor.The microsurgical management used was aimed at enucleating the chemical membrane,performing apicoectomy of the tooth along with careful and precise retrograde filling,and implementing GTR technique using a resorbable collagen membrane and bovine xenograft.The diagnosis of radicular cyst was confirmed using histopathological analysis.The patient underwent follow-up evaluations at 10 and 30 d postoperatively.At 4 months postoperative evaluation,she remained asymptomatic,and radiographs showed significant periapical healing with adequate bone formation.CONCLUSION These results suggest that microsurgical management using the GTR technique with collagen membrane and xenograft,contributes to bone regeneration.
