Demographic and clinical characteristics of the study population (mean ± SD).

Variable	Control group (𝑁=10)	Saline group (𝑁=10)	EO group (𝑁=10)
Age (years)	55.4 ± 9.3	55.6 ± 10.0	54.1 ± 8.7
Gender (𝑛)
Male/female	8/2	6/4	6/4
Smoking (𝑛)
Smoker/nonsmoker	4/6	3/7	3/7
Number of teeth	24.0 ± 3.2	24.2 ± 3.9	23.4 ± 2.5
PPD (mm)	15/10/5	16/9/5	15/8/7
CAL (mm)	3.7 ± 0.7	3.8 ± 0.8	4.0 ± 0.9
BOP (% positive)	3.8 ± 0.5	3.9 ± 0.7	4.0 ± 1.0
	52.0 ± 18.7	54.3 ± 16.6	52.9 ± 15.9

EO: essential oil-containing antiseptic; PPD: probing pocket depth; CAL: clinical attachment level; BOP: bleeding on probing. No statistically significant difference at the 0.05 level was observed for any variables between the groups (Kruskal-Wallis test).
