Use of Injectable Platelet Rich Fibrin in Lichen Planus

Platelet Rich Fibrine (PRF), which promotes wound healing by supporting angiogenesis, immunity and epithelial proliferation phases. over a decade has since past since PRF was developed and many clinicians now point to the potential use of a liquid version of PRF. a liquid injectable-platelet-rich fibrin (i-PRF) was developed by modifying spin centrifugation forces. At lower centrifugation speeds and by utilizing non-glass centrifugation tubes, the fibrin coagulation could be slowed down at early time points thus generating an injectable PRF. Much like traditional PRF, i-PRF contains an increase in leukocyte number and is further able to stimulate growth factor release. Lichen planus is a common chronic mucocutaneous inflammatory disorder which generally affect s middle aged adults. Therapeutic methods including topical and systemic corticosteroids for the treatment of oral lichen planus (OLP) are suggested. However, long -term use of corticosteroids may be associated with local and systemic complications, and moreover, some patients may not be responsive. The investigators aimed to apply a treatment of autogenous origin (including no foreign products), considering the side effects of our corticosteroids. The study was designed as a split mouth. The investigators planned to administer I-PRF to one side and intralesional corticosteroid therapy to the other side at patients with bilateral atrophic / erosive oral lichen planus lesions
