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

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.
