Periapical cyst enucleation and lumina bone and L-PRF filling: case report

RELATO DE CASO

Abstract

Introduction: The root cyst originates from a periapical granuloma with preexisting epithelium, which
constitutes a focus of granulation tissue, chronically inflamed, at the apex of a tooth without vitality. The
prevalence of the radicular cyst corresponds to about 60% of the maxillary and mandible cysts, representing
the most common odontogenic cysts. Objective: The objective of this study is to report a clinical case of
periapical cyst enucleation and cavity filling with biomaterial and platelet and leukocyte-rich fibrin (L-PRF).
Case report: CAFS, male patient, 62 years old, asymptomatic and referred for endodontic treatment to the
tooth 34. After radiological examination, radiolucent lesion was detected with defined limits involving the root
apices of the teeth 33, 34 and the region of 35 (absent), with a periapical cyst hypothesis. It was planned for
the enucleation of the cystic lesion and filling of the bone antrum with the synthetic bovine bone (LuminaBone) and L-PRF, for better healing and aid in the new bone formation, better final results of the surgery,
besides reducing inflammatory reaction and also assisting in the repair of cut. Final Considerations: L-PRF
presents itself as a viable alternative in the control of inflammatory conditions, helping the gingival repair
process and stabilizing the grafting material, thus allowing the future rehabilitation of the patient through
osseointegrable implants. The anatomopathological diagnosis of the case was confirmed as periapical cyst
