      <study_design>Randomization: Randomized, Blinding: Not blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: Thirty-eight patients who refer to the Department of Surgery of the School of Dentistry for their wisdom tooth surgery agree to carry out this research project and complete informed consent and form our study community. Patients are randomly selected and in each patient, the selection of one side tooth as control or test will be by simple randomization using coins in the form of taps/lines. Each patient who enters the study will be assigned a code from 1 to 38.</study_design>

      <i_freetext>Intervention 1: Control group: All patients were randomly selected and after completing the questionnaire, they were approved by at least two professors of the surgical department. Before the operation, chlorhexidine mouthwash was prescribed and gelofen was administered to them.  Extraction of both teeth will be performed by a surgeon under the same conditions.  To anesthetize patients, 3 carpol lidocaine containing epinephrine 1 in 80,000 was used and performed with lower alveolar block and long buccal technique.  In patients in this group, teeth are extracted normally.  To unify the patients, if the time difference between the two operations (from the beginning of the operation to the moment of the last suture) is more than 10 minutes, the patient will be excluded from the study.  Silent examination (pain, unpleasant odor and lack of proper clot formation in the extracted tooth cavity) are examined;  Patients are given questionnaires that indicate their pain on the first, second and ... days until the 7th day in the form of numbers from 1 to 10.  Clinical examination of the patient and completion of information forms are used to collect information and VAS method is used to assess pain. Intervention 2: Intervention group: All patients were randomly selected and after completing the questionnaire, they were approved by at least two professors of the surgical department. Before the operation, chlorhexidine mouthwash was prescribed and gelofen was administered to them.  Extraction of both teeth will be performed by a surgeon under the same conditions.  To anesthetize patients, 3 carpol lidocaine containing epinephrine 1 in 80,000 was used and performed with lower alveolar block and long buccal technique.  After tooth extraction, an antimicrobial porous gelatin gel (containing curcumin nanoparticles) is placed inside the cavity. The prepared gelfomes were cut into 1: 1 by 1 cm dimensions and sterilized by gamma rays. Zelfum has a spongy structure with pores of 200 nm and a loading percentage of 96% curcumin and a slow release pattern of curcumin. To unify the patients, if the time difference between the two operations (from the beginning of the operation to the moment of the last suture) is more than 10 minutes, the patient will be excluded from the study.  Silent examination (pain, unpleasant odor and lack of proper clot formation in the extracted tooth cavity) are examined;  Patients are given questionnaires that indicate their pain on the first, second and ... days until the 7th day in the form of numbers from 1 to 10.
