Effectiveness of the platelet-rich fibrin membrane associated to coronally repositioned flap

Abstract

Introduction: Coronally repositioned flap constitutes an advanced technique for the treatment of periodontal recession. When combined with different biomaterials the results are much more encouraging regarding root coverage and stability in time. Objective: to assess the effectiveness of the platelet-rich fibrin membrane combined with coronal repositioned flap in the root coverage. Methods: A quasi-experimental research was carried out in patients treated at the periodontal office of the Dentistry faculty in Villa Clara province from March 2017 to May 2019. The population was constituted by 41 patients who suffered from periodontal recession and required root coverage using coronally repositioned flap. An intentional non-probabilistic sample was used resulting in 26 patients with the established criteria. Study and control sites were established. Variables such as age, sex, recession length, root coverage, Miller’s classification, width and gaining of the attached gingiva, assessment categories and effectiveness of treatment were studied. Results: A favorable assessment category was predominant in 92,45 % of teeth located in the study sites. The percentage of effectiveness of treatment was higher in the study sites in 33,96 % in relation to the control sites . Conclusions: The treatment of the platelet-rich fibrin membrane associated with coronally repositioned flap was considered more effective.
