Comparison of bleeding on probing between two sites and across time at each site

BOP	Mean±SD		P
	Test site (n=21)	Control site (n=21)
Baseline	64.10±7.67	64.43±7.58	0.888 (NS)#
1 month	41.10±3.58	45.29±3.90	0.001 (S)#
3 month	38.00±3.62	46.81±4.33	<0.0001 (S)#
P	<0.0001 (S)**	<0.0001 (S)**

^#Obtained using paired t-test; **Obtained using repeated measures of ANOVA; P<0.05 implicating statistically significant difference; BOP: Bleeding on probing; NS: Not significant; S: Significant; SD: Standard deviation
