      <study_design>Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: Sampling Method is randomly Available among Individuals referring to pediatric Department of Tabriz Dental faculty. The randomization Method is simple and the Unit is individual, our Tool for randomization is the randomized Number Chart. Furthermore, the Allocation of treatment to Patients is done Randomly. To do this, the types of treatment are identified with code A (control) and B (case) and then the sealed in Envelopes that will be placed in a Box and stirred.  Then they are randomly chosen from the Box and after observing the code, the treatment is given to the Patient.  None of the Patients will be informed about another Patient's treatment, Blinding description: Participants do not know that different types of treatment are being studied. They are also totally blinded to the information of the other Participants.</study_design>
