Efficacy of injectable platelet-rich fibrin in the erosive oral lichen planus: a split-mouth, randomized, controlled clinical trial.

Objective: Our study compared the effects of injectable platelet-rich fibrin (i-PRF) with those of corticosteroids in the treatment of erosive oral lichen planus (EOLP).

Methodology: This split-mouth study included 24 individuals diagnosed histopathologically with bilateral EOLP. One bilateral lesion was injected with i-PRF, whereas the other was injected with methylprednisolone acetate in four sessions at 15-day intervals.

Injectable platelet-rich fibrin and microneedling for gingival augmentation in thin periodontal phenotype: A randomized controlled clinical trial.

Aim: The aim of this present study was to evaluate the effect of gingival thickness (GT) and keratinized tissue width (KTW) using injectable platelet-rich fibrin (i-PRF) alone and with microneedling (MN) in individuals with thin periodontal phenotypes.

Materials And Methods: In this split-mouth study, 33 systemically healthy patients with thin periodontal phenotypes were randomly treated with MN + i-PRF and i-PRF. I-PRF was injected on one side, and MN + i-PRF was performed on the other side of the same patient at 4 sessions with 10-day intervals.
