Effect of leukocyte and platelet-rich fibrin on free gingival graft healing: A clinical and histological study in rabbits.

Recently, the use of leukocyte- and platelet-rich fibrin (L-PRF) has been recommended due to the presence of various growth factors to increase the success of free gingival grafts (FGG). This study evaluated the effect of using L-PRF in the healing of FGG in rabbits. Twenty rabbits were randomly divided into two groups.
