Effects of Systemic Simvastatin on the Concentrations of Visfatin, Tumor Necrosis Factor-α, and Interleukin-6 in Gingival Crevicular Fluid in Patients with Type 2 Diabetes and Chronic Periodontitis

Table 3

Correlations between the levels of visfatin, tumor necrosis factor-α, and interleukin-6 in gingival crevicular fluid and probing depth, clinical attachment level, and bone density.

	TNF-α		IL-6		Visfatin
		value		value		value
CAL	0.728	0.001	0.727	0.001	0.766	0.001
PD	0.622	0.001	0.620	0.001	0.590	0.001
Bone density	0.641	0.001	0.642	0.001	0.568	0.002

r, Spearman’s rank correlation coefficient; CAL, clinical attachment level; PD, probing depth; TNF-α, tumor necrosis factor-α; IL-6, interleukin-6. is statistically significant.
