      <study_design>Randomization: Randomized, Blinding: Triple blinded, Placebo: Not used, Assignment: Parallel, Purpose: Supportive, Randomization description: wax-sealed envelope are used.Envelops containing name Left or Right are prepared randomly.After the third molar removed by surgeon, the pockets are opened by surgical assistant, and according to this, the assistant inserts the L-PRF into desired cavity. One side is selected as the Intervention group, and the other side is only sutured as Control group, Blinding description: During surgery,after the surgeon extract the wisdom teeth from both sides, they leave the operating room and the surgical assistant,based on randomly opened envelope, place the L-PRF inside one of the sockets and sutures each socket with same suture. These processes are carried out by a surgeon and surgical assistant, neither of whom participates in data analysis or evaluation stages.</study_design>

      <i_freetext>Intervention 1: Intervention group:  In each patient,After extraction of both sides,one extraction socket is randomly treated with L-PRF and sutured.Patients will follow up in terms of wound healing for 2 weeks. Intervention 2: Control group:  In each patient,After extraction of both sides,one extraction socket without any intervention sutured.Patients will follow up in terms of wound healing for 2 weeks.</i_freetext>
