      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Supportive, Randomization description: Random sampling will be done among the patients referred to Tabriz Dental Faculty who are eligible for the study. The randomization method is simple and its unit is individual. Our tool for randomizing a table of random numbers. Based on this, the type of treatment is marked with code A (20 ppm ozone gel), B (1% chlorhexidine gel), and C (control) and placed inside sealed envelopes. Then the envelopes are placed in a bag and mixed. Then it is randomly selected from the bag and treatment is given to the patient by observing the code.
In order to avoid selection bias, the random assignment of people to the study groups will be concealed and will remain hidden until the interventions are carried out. None of the patients will be informed about the treatment of another patient, Blinding description: This study is double-blind. Patients are aware of the existence of some types of treatment, but they do not know which group they belong to. After preparation, the gels will be transferred to containers with the same shape and packaging and will be labeled, and only the code of the gels will be recorded on the label (blinding of the treatable people) and only one of the collaborators of the project will know the content of the gels and he knows how to allocate the patients in the groups, he will distribute the gels among the patients, and the examination and taking of plaque samples will be done by another colleague of the project who does not know the type of patient group (blinding of the treating people).</study_design>

      <i_freetext>Intervention 1: The first intervention group: O3life 20 ppm ozonated gel is applied twice a day (morning and night) half an hour after meals for 3 weeks using a finger on all dental surfaces. After three weeks, the final plaque index and the number of Streptococcus mutans bacteria will be calculated. Intervention 2: The second intervention group: HEXIGEL 1% chlorhexidine gel is applied twice a day (morning and night) half an hour after meals for 3 weeks using a finger on all dental surfaces. After three weeks, the final plaque index and the number of Streptococcus mutans bacteria will be counted. Intervention 3: Control group: The patient's clean finger is rubbed twice a day (morning and night) half an hour after meals for 3 weeks on all dental surfaces. After three weeks, the final plaque index and the number of Streptococcus mutans bacteria will be calculated.</i_freetext>
