Comparative evaluation of coronally advanced flap and semilunar coronally repositioned flap, using platelet-rich fibrin in Miller’s Class I recession defects: A randomized clinical trial

Abstract

Background: For a periodontist, treating recession is always a proud moment and a challenging task. The current trial aimed at comparing and clinically evaluating semilunar coronally repositioned flap (SCRF) and coronally advanced flap (CAF) procedures combined with platelet-rich fibrin (PRF) in the management of Miller’s Class I recession defects. Materials and Methods: Thirty-six recession sites were randomly divided into the CAF or SCRF groups. Gingival thickness (GT), root coverage percentage (%RC), plaque index (PI), gingival bleeding index (GBI), and clinical attachment level (CAL) were measured at baseline and 3 and 6 months. Recession height (RH), recession width (RW), and width of keratinized tissue (WKT) were also measured. With significance set at p=/ 0.05). Further, intergroup comparison showed no significant difference in both the groups for all the parameters except for %RC where significance was reported at 1 month (P = 0.015*) and 3 months (P = 0.013*) when compared from baseline to 6 months. Conclusion: Root coverage is better in CAF with PRF than SCRF with PRF, in the treatment of gingival recession. PRF helped in soft-tissue healing and increased in GT.
