Evaluation of the use of platelet-rich fibrin dressing in the management of free gingival graft clinical study

Abstract

Aim of the study: To evaluate the use of platelet-rich fibrin (PRF) dressing in the free gingival graft (FGG) recipient site by evaluating tissue healing and coverage of recession. Materials and methods: The study included 40 patients having at least one site with Miller’s class II recession to be treated via FGG. The participants were divided into two groups: PRF group consisted of 20 patients who had PRF dressing used over the FGG and Coe-Pak™ group comprising 20 patients who received normal dressing (Coe-Pak™). Clinical periodontal parameters, healing index, root cover, and attached gingival width (AGW) were recorded prior to treatment and at 1 and 3 months postsurgery. A statistical analysis was performed to examine the differences between the study groups. Results: The PRF group showed statistically significant differences in the level of healing index and root coverage. Conclusion: It may be concluded, within the study limits, that PRF dressing plays important role in the process of FGG healing. Clinical significance: Platelet-rich fibrin can be considered a useful reliable dressing.
