Characteristics	Healthy; ()	Gingivitis; ()	Periodontitis; ()
Demographic characteristics
Age in years	26.72 ± 8.59	27.43 ± 10.36	49.16 ± 13.93
Female (%)	81.81	50.00	68.42
Periodontal parameters
Salivary pH	6.92 ± 0.45	6.95 ± 0.33	6.97 ± 0.36
GI (%)	11.09 ± 4.34	41.06 ± 18.36	56.44 ± 29.58
BOP (%)	12.69 ± 3.11	33.04 ± 15.96	52.33 ± 28.13
CAL index scores	0.00 ± 0.00	0.91 ± 0.25	1.44 ± 0.42
PD index scores	0.97 ± 0.11	1.06 ± 0.01	1.18 ± 0.17

GI: gingival index, BOP: bleeding on probing, CAL: clinical attachment loss, and PD: probing depth.
PD index score in each individual = (1 × number of sites with PD score 1) + (2 × number of sites with PD score 2) + (3 × number of sites with PD score 3)/total measured PD sites.
CAL index score in each individual = (1 × number of sites with CAL score 1) + (2 × number of sites with CAL score 2) + (3 × number of sites with CAL score 3)/total measured CAL sites.
Mean ± SD.
Statistical analysis: One-way ANOVA.
