Periodontal status at baseline and post-intervention

Variable	Baseline	After 8 weeks	Δ	P-value	P-value*	P-value**	P-value***
PD (mm)
Control group (n=21)	4.85±1.01	4.66±0.91	−0.19±0.51	0.1	0.77	0.51	0.04
Intervention group (n=21)	4.95±1.16	4.42±1.39	−0.52±0.51	<0.001
CAL (mm)
Control group (n=21)	3.00±0.77	2.85±0.72	−0.14±0.35	0.08	0.85	0.07	0.003

Notes: Values are expressed as means±SD. P<0.05 was considered as significant using Paired t-test. *P<0.05 was considered as significant using independent t-test between the two groups at baseline. **P<0.05 was considered as significant using independent t-test between the two groups post-intervention. ***P<0.05 was considered as significant changes using independent t-test between the two groups post-intervention. Δ: difference between PD (mm) and CAL (mm) at baseline and after 8 weeks.

Abbreviations: CAL, clinical attachment loss; PD, pocket depth.
