      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Prevention, Randomization description: In order to randomly assign qualified people to two groups, the Random allocation software version 2 will be used, and the random allocation method will be also a simple random method. First, the first eligible person will get number 1, and then the eligible people will get number 36, and based on the random allocation done by the software, each person will receive medicine A or B. In order to blind the random allocation, the list of random allocation will be provided to another person who is not in the study and before the patient's visit based on the number, the individual's treatment group will be asked by the third person by phone or SMS, Blinding description: Both mouthwashes will be put in similar bottles, the contents of which are not known. In order to blind the researcher, the researcher herself, who examines and performs the measurements, will have no knowledge of the type of substance inside the bottles.</study_design>

      <i_freetext>Intervention 1: Intervention group: This group is given Nigella sativa mouthwash. Patients are told to use 10 milliliters of mouthwash twice a day for 30 seconds for two weeks. The extract is obtained from a grocery in Yazd and used to produce mouthwash. Mouthwash is prepared with a concentration of 20%. Intervention 2: Control group: This group is given chlorhexidine mouthwash. 0.2% chlorhexidine solution (Shahr Daru, Iran) is used twice a day, 10 ml each time, for 30 seconds for two weeks.</i_freetext>
