      <study_design>Randomization: Randomized, Blinding: Triple blinded, Placebo: Used, Assignment: Parallel, Purpose: Prevention, Randomization description: Block randomization: 
For this purpose, after creating a computer-generated random sequence using Winpepi software, equal blocks of 6 will be used. unit of randomization is individual and randomization tool is sealed envelopes. These steps are performed by an independent statistician who is also responsible for transferring the envelopes containing the treatment code to the pharmacist in charge of the making of the treatment and placebo products, Blinding description: When entering the study, each of the participants will be given a number, which is transferred to the pharmacist in charge of the making of the treatment and placebo products. 
The participants, the person evaluating the results of the intervention and the data analyst will not know the type of treatment of the people.
Therapeutic products and placebo are packed in exactly the same opaque sealed bags, there is no difference in terms of color, smell and taste, and the label does not specify the nature of the treatment or placebo.</study_design>

      <i_freetext>Intervention 1: Intervention group: participants in this group brush their teeth twice a day for 4 weeks, using toothpaste containing post-biotic Bifidobacterium animalis subsp. animalis with a concentration of 2*10^ 9. Intervention 2: Intervention group: participants in this group wash their mouths daily for 4 weeks, using a mouthwash containing post-biotic Bifidobacterium animalis subsp. animalis with a concentration of 2*10^ 9. Intervention 3: Control group: Participants in this group use mouthwash and toothpaste similar to the intervention groups daily for 4 weeks. The only difference between toothpaste and mouthwash used by this group will be the absence of post-biotic.</i_freetext>
