Table 1.

Alveolar bone level and numbers of inflammatory cells counted in the connective tissue and epithelium.

	Alveolar bone level*	Inflammatory cells*	Inflammatory cells*
	(mm)	connective tissue	epithelium
		(cells/1600 μm2)	(cells/1600 μm2)
Group 1	1.08 ± 0.03	3.9 ± 0.7	3.4 ± 0.8
(Experimental periodontitis with 10 days period)	1.08 (1.03–1.13)	4.0 (3.0–5.0)	3.0 (2.0–5.0)
Group 2	1.37 ± 0.05	5.4 ± 1.2	4.5 ± 0.7
(Experimental periodontitis with 40 days period)	1.39 (1.29–1.44)	5.5 (4.0–7.0)	4.0 (4.0–6.0)
Group 3	0.93 ± 0.07	0.5 ± 0.5	0.3 ± 0.5
(Healthy control group)	0.96 (0.80–1.01)	0.5 (0.0–1.0)	0.0 (0.0–1.0)

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

*Significant difference in histomorphometric findings between groups (P < 0.001).
