# Comparative evaluation of VISTA using platelet-rich fibrin and placental membrane for multiple gingival recession

## TL;DR

This study compares two biomaterials used with a dental technique to treat gum recession and finds they are equally effective.

## Contribution

The study provides evidence that PRF and placental membrane are equally effective when used with the VISTA technique for treating gingival recession.

## Key findings

- Both PRF and placental membrane showed significant improvement in clinical parameters over six months.
- No statistically significant differences were found between the two biomaterials in treating gum recession.
- The VISTA technique combined with either biomaterial is effective for multiple gingival recessions.

## Abstract

Gingival recession is a prevalent clinical problem and limited evidence exists comparing biological membranes used with the VISTA
technique for its correction. Therefore, it is of interest to evaluate the effectiveness of VISTA combined with Platelet-Rich Fibrin
(PRF) versus placental membrane in 20 sites with Miller's Class I/II recession. Both groups demonstrated significant improvement in all
clinical parameters-including RD, RW, CAL, WKG and GT-over a 6-month period (p<0.001). Intergroup comparisons revealed no statistically
significant differences between PRF and placental membrane across all evaluated variables. Both biomaterials were equally effective when
combined with the VISTA technique, supporting their interchangeable use in managing multiple gingival recessions.
