Correlation coefficients (R) for salivary IL-1β, IL-1Ra, IL-8, MCP-1, and VEGF levels between the visits at baseline and at day 4, 7, 10, and 24

	Baseline vs. day 4	Baseline vs. day 7	Baseline vs. day 10	Baseline vs. day 24
IL-1β	0.33	0.45*	0.38	0.66**
IL-1Ra	0.38	0.37	0.44*	0.85**
IL-8	0.48*	0.46*	0.53*	0.79**
MCP-1	0.63**	0.50*	0.68**	0.40*
VEGF	0.40*	0.40*	0.54*	0.80**

*p < 0.05; **p < 0.01.

IL, interleukin; IL-Ra, IL-1 receptor antagonist; MCP-1, monocyte chemoattractant protein; VEGF, vascular endothelial growth factor.
