      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Prevention, Randomization description: This study will be performed as a randomized double-blind trial in which the patient and the examiner will be absolutely unaware of the contents of the envelope provided to the surgeon. To this end, a total of 34 apparently similar envelopes will be selected and placed in a 17 surgical card packs together with gelofen, and the other 17 surgical envelopes contain no gelofen. The surgeon chooses randomly one of the envelopes before surgery, and will perform the operation according to the envelope type, Blinding description: In this double-blind study, only the researcher( surgeon) will be informed of the main drug or placebo assigned to each patient.  The participants will not be informed of the sucket contents of the surgery .The patient does not see a dental sucket during surgery and the evaluator is also absent during surgery.Neither the participant nor evaluator not know who is in which group .</study_design>

      <i_freetext>Intervention 1: The intervention group is treated with gelofen-containing gelfoam in the socket of wisdom teeth. The contents of a 400 mg gelofen tablet (Jaber-ibne Hayan Co., Iran) is discharged by a syringe containing 1 cc of gelofen, then transferred to the gelfoam(Apadanatac Co.,Iran). Intervention 2: Control group: The control group is treated with gelofen-free gelfoam (Apadanatak Co.، Iran. placebo)in the socket of wisdom teeth.</i_freetext>
