Gingival tissue and serum PTX3 levels in experimental periodontitis and control groups (ng/mL).

	Gingival tissue	Serum*
Group 1	1.6 ± 0.4a	1.2 ± 0.3
(Experimental periodontitis with 10 days period)	1.5 (1.3–2.4)	1.1 (0.9–1.6)
Group 2	1.2 ± 0.2b	1.1 ± 0.2
(Experimental periodontitis with 40 days period)	1.2 (1.0–1.5)	1.1 (0.9–1.4)
Group 3	1.1 ± 0.2b	1.0 ± 0.2
(Healthy control group)	1.1 (0.9–1.5)	1.0 (0.8–1.3)

Data were analyzed by one-way ANOVA and expressed as the means ± standard deviation and medians (minimum-maximum).

^aSignificant difference between groups 2 and 3 (P < 0.01).

^bNo significant difference between groups (P > 0.05).

*No significant difference in serum PTX3 levels between groups (P > 0.05).
