Figure 2

Scatter plot of difference (∆) in IL-8 and (∆) in clinical indices. (A) Difference (∆) in salivary interleukin-8 (ng/mL) and difference (∆) in plaque index (%). (B) Difference (∆) in salivary interleukin-8 (ng/mL) and difference (∆) in bleeding on probing (%). (C) Difference (∆) in salivary interleukin-8 (ng/mL) and difference (∆) in pocket depth (mm). ∆IL-8 = baseline IL-8–after treatment IL-8; ∆plaque index = baseline plaque index–after treatment plaque index. ∆Pocket depth = baseline pocket depth–after treatment pocket depth.
