  • Change from Baseline IL-8 level of GCF at 2 months

    GCF samples were collected with paper strips and IL-8 levels of GCF were measured using commercial kits by using ELISA method

    baseline, 1st and 2nd months

  • Change from Baseline IL-10 level of GCF at 2 months

    GCF samples were collected with paper strips and IL-10 levels of GCF were measured using commercial kits by using ELISA method

    baseline, 1st and 2nd months

Secondary Outcomes (3)

  • Change from Baseline GCF volume at 2 months

Randomization was performed by one researcher that had never any role in participant's treatment and clinical measurement processes (E.O.E). Patients' all measurements and treatments were made by a single researcher who doesn't know in which group participants were included (N.E.).
