摘要：Leukocyte-platelet rich fibrin is an aggregate obtained by centrifuging the patient's own blood, it is rich in platelets, growth factors and cytokines and seems to improve the healing of the surgical wound and alleviate postoperative morbidity in cases of root coverage. The aim of this study is to report and discuss a clinical case of multiple gingival recessions treated with the association of the coronary repositioned flap and leukocyte-platelet rich fibrin. Patient, female, 28 years old, complaining of dentinal hypersensitivity and esthetic dissatisfaction. After physical and radiographic examinations, type 1 gingival recessions were observed in teeth 22, 23 and 24. Surgical planning included oblique paramarginal incisions starting from the cementoenamel junction of tooth 23 towards the gingival margin of adjacent teeth, flap detachment, then venipuncture and centrifugation at 2,494 revolutions per minute (700 g) for 12 minutes. At the end of this process, membranes were obtained, which were positioned and sutured over the gingival recessions, followed by coronary repositioning of the surgical papillae. In the postoperative period, satisfactory tissue repair was observed. Although the gold standard for root coverage is connective tissue grafting associated with the coronary repositioned flap, platelet aggregates stimulate the repair and regeneration of soft and hard tissues and can be a great option in some cases. In this clinical case, it was possible to perceive the beneficial effects of the use of leukocyte-platelet rich fibrin membrane in the treatment of gingival recessions.
