Measurements	Control (healthy site) (n = 15)	Chronic periodontitis (n = 15)	Generalized aggressive periodontitis (n = 15)
PD (mm)	1·27 ± 0·45	6·8 ± 1·65***	7·07 ± 1·48***
CAL (mm)	1·27 ± 0·45	8·4 ± 2·35***	8·07 ± 1·79***

Significance of differences compared to the control group (^***P < 0·0001; ^**P < 0·01; ^*P < 0·05). Values represent means ± standard deviations. PD = pocket depth; CAL = clinical attachment loss; PI = plaque index; BOP = bleeding on probing.
