The participants were randomly assigned to three groups: interproximal brush, water flosser, and dental floss.

Conversely, both the interdental brush and dental floss exhibited a slight increase in IL-6 levels at the second visit (60.73 ± 2.93 and 55.7 ± 10.64, respectively) compared to the mean at the first visit (58.38 ± 3.24 and 54.6 ± 2.22, respectively).
