Comparative evaluation of effect of injectable platelet-rich fibrin with collagen membrane compared with collagen membrane alone for gingival recession coverage

Figure 4 Comparison of injectable platelet-rich fibrin + collagen membrane and collagen membrane at different time intervals. A: Comparison of mean plaque index (PI) scores; B: Comparison of mean gingival index (GI) scores; C: Comparison of mean pocket depth (PD) scores; D: Comparison of mean recession depth (RD) scores; E: Comparison of mean recession width (RW) scores; F: Comparison of mean relative attachment level (RAL) scores; G: Comparison of mean keratinized tissue width (KTW) scores; H: Comparison of mean keratinized tissue thickness (KTT) scores. CM: Collagen membrane; i-PRF: Injectable platelet-rich fibrin; PI: Plaque index; mo: Month.
