Comparative Evaluation of Coronally Advanced Flap Using Platelet-rich Fibrin Membrane and Fresh Amniotic Membrane in Gingival Recession

Abstract

Background: the aim of this study was to evaluate and compare the effectiveness of root coverage with coronally advanced flap combined with Platelet Rich Fibrin or Fresh Amniotic Membrane. Materials and Methods: thirty patients had Miller class I or II in maxillary anterior teeth were involved in the present study. Each recession defect was randomly assigned to one of the treating groups: coronally advanced flap with Platelet rich fibrin (PRF group) and coronally advanced flap with fresh amniotic membrane (AM) (AM Group). Clinical measurements of recession depth (RD), root coverage percentage (RC%) pocket depth (PD), clinical attachment level (CAL) and width of keratinized tissue (WKT) were evaluated at the baseline, three months, six months and nine months postoperatively. Statistical analysis was performed for intergroup and intragroup comparisons respectively. Results: intragroup comparison displayed statistical significant difference with regard to RD and CAL at different time interval. No statistical significant difference between groups at different time interval with regard to RD, PD, CAL while WKT, AM group demonstrated statistical significant increase compared to PRF group. Conclusion: Both the membranes provided successful and predictable root coverage when combined with CAF. AM was more effective in terms of increase in WKT.

Comparative evaluation of modified triangular coronally advanced Flap alone or in combination with platelet rich fibrin or type I collagen membrane for treatment of Miller’s Class I and Class II gingival recession

“…On intergroup comparison between the three groups, no significant difference were seen at baseline and 6 months. This was found in accordance with a study done by Shalaby et al 2019 13 On comparing the CAL and GRD between the three groups no statistically significant difference was observed from baseline to 6 months. It is in accordance to a study by Raval et al 2022 14 which showed statistically no significant p-value while comparing the effect of PRF and Xenogenic collegen member in the treatment of gingival rcession using coronally advanced flap.…”
