RESUMEN
Along with the better understanding of the pathogenesis of periodontal diseases, the treatment modalities for various periodontal diseases have also gone a step ahead. One of the most important and currently unsolved problems in clinical periodontics is the predictable successful treatment of inadequate width of attached gingiva. Recently, importance has been given to the use of platelet-rich fibrin (PRF) for predictably treating periodontal diseases. PRF is an intimate assembly of glycan chains, glycoproteins, and cytokines. These are enmeshed in a slowly polymerized fibrin network which has the potential to accelerate soft and hard tissue healing. This article presents the clinical results of treatment of inadequate width of attached gingiva with PRF.
