Abstract: Gingival recession is a common condition in the population that often requires treatment because of its adverse consequences. Among the various treatment options available, connective tissue graft has demonstrated the best rate of effectiveness. However, this treatment involves harvesting connective tissue from the palate leading to additional surgical pain and wound healing problems. Recently, a platelet concentrate called “Platelet Rich Fibrin”, has been used as a substitute material to prevent several disadvantages related to connective tissue grafting. However, is the use of Platelet Rich Fibrin effective in treating gingival recessions? The objective of this study was to compare the efficacy of both protocols in terms of root coverage. We also measured the level of patient postoperative pain following each of the grafting procedure. This study includes a randomization of the chosen technique and measures were taken by simple blindness. At the dental clinic of periodontics of Université Laval, a total of 22 grafts were made with the Platelet Rich Fibrin, and 12 grafts with the connective tissue. During the first 10 days after the procedure, a pain questionnaire was completed by all of the patients. The final root coverage measurements were taken 6 months after the procedure. According to our results, the root coverage was significantly better with the connective tissue graft. However, postoperative pain was significantly greater following the connective tissue grafts as compared to Platelet Rich Fibrin grafts. These results confirmed that connective tissue graft remains the best option for treating gingival recessions. Nevertheless, the use of Platelet Rich Fibrin remains a valid treatment option in order to avoid greater postoperative pain.
