Comparative evaluation of the efficacy of coronally repositioned flap with PRF and with placental membrane allograft (Amniotic Membrane) in the treatment of gingival recession

Abstract

Gingival recession presents a significant aesthetic problem in dental patients. A variety of surgical techniques have been used to cover these defects. The present study was carried out on 30 selected sites having either Miller’s Class I or II marginal tissue recession. This is a clinical study designed as a split mouth randomized controlled trial. Each site constitutes one sample of the study. 15 sites were randomly assigned for the test group (Coronally Advanced Flap with Amnion membrane) and another 15 sites were assigned for the control group (CAF with PRF). All subjects received clinical periodontal examination by a single examiner.There was a statistically non significant difference seen for the values between the inter and intra groups (p>0.05) for RD at all time intervals.Both the treatment modalities for gingival recession coverage demonstrated a significant improvement in the recession coverage and width of keratinized gingiva and can be used in treatment of gingival recession defects.
