Evaluation of the efficacy of Leukocyte-Platelet Rich Fibrin (L-PRF) membranes on the initial healing of intra-oral surgical buccal flaps removed over sticky bone (comparative clinical study)

Abstract

Background and Aim: this study was aimed to evaluate the efficacy of L-PRF membranes in comparative with collagen membranes on the initial healing of intra-oral surgical buccal flaps removed over sticky bone in the context of socket preservation after dental extraction.

Materials and Methods: The sample was included 30 buccal flaps with in 30 patients (30-50 years old) whose were submitted to socket preservation with sticky bone. The study was designed by applying L-PRF membranes in half of the sample (the study group, its' symbol is [PRF]) and applying collagen membranes in the other half (the control group, its' symbol is [COL]). 

Results: Using the digital coding of Galli.F et al that is used to evaluate the healing of intra-oral surgical incisions, the results of statistical tests exhibit that ten days after surgery there were significant differences between the means of two groups for the sake of PRF group. The mean was 0.56 for [PRF] and 0.9 for [COL].

Conclusion: The using of L-PRF membranes over sticky bone grafts enhanced and accelerated the initial healing of intra-oral surgical buccal flaps in the context of socket preservation after dental extraction in the posterior region of maxilla in comparative with collagen membranes.
