Comparison of gingival index scores in control group and experimental group at different time intervals

Time intervals	Groups	Gingival index scores		Unpaired t-test
		Mean±SD	Minimum-maximum
Baseline	Control group	1.61±0.26	1.20-2.20	t=1.08,
	Experimental group	1.75±0.31	1.20-2.20	P=0.29#
At 6th month	Control group	0.88±0.13	0.60-1.10	t=1.84,
	Experimental group	0.76±0.15	0.60-1.10	P=0.08#

^#Nonsignificant. SD – Standard deviation; t – t test value; p – probability value (p= 0.01)
