Table 4

Intergroup OHI and GI scores comparison postinterventions.

Groups	OHI scores			GI scores
	Mean difference	95% CI	value	Mean difference	95% CI	value
Group 1 (pictorial) vs. group 2 (video)	-0.097	-0.27, 0.07	0.537	-0.124	-0.31, 0.05	0.290
Group 1 (pictorial) vs. group 3 (control)	-0.274	-0.45, -0.09	0.001	-0.342	-0.52, -0.15	0.001
Group 2 (video) vs. group 3 (control)	-0.177	-0.35, 0.01	0.052	-0.218	-0.40, -0.03	0.015

OHI: oral hygiene index; GI: gingival index; CI: confidence interval; value of ≤0.05 was considered as statistically significant.
