The Effect of Using Injectable Platelet-rich Fibrin on Root Surface Closure in Patients with Gingival Recession.

Local anesthesia will be applied to the area with gingival recession. Before the procedure, the venous blood taken from the patient will be centrifuged at 700 RPM for 3 minutes in glass and non-addition tubes to obtain i-PRF. i-TZF will be taken into a 2 cc injector. In 2020, Özsağır et al. Decortication, that is, microneedling, will be performed with insulin needle tips according to the protocol defined by Dr. Then the prepared i-PRF will be infected to the apical mucogingival junction of the keratinized gingival area. This process will be repeated once a month for 3 months. After the 3rd month, the horizontal and vertical gingival recession values will be evaluated and recorded at the end of 6 months and 1 year.
