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.

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 =/<0.05 and <0.001, the Chi-square test was used to analyze intragroup data and the paired -test was used to analyze intergroup differences.

RESULTS

Intragroup comparison showed a statistical significance for all the clinical parameters i.e. RW ( = 0.00*), RD ( = 0.00*), CAL ( = 0.00*), and GT ( = 0.042*) of the CAF group except for PD ( = 1.00) and WKT ( = 0.331) whereas, the SCRF group showed statistical significance for WKT ( = 0.001*) and GT ( = 0.00*). Remaining parameters of SCRF group were non-significant when compared from baseline to 6 months ( > 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 ( = 0.015*) and 3 months ( = 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.
