Mean and SD values of keratinized tissue thickness at 2 mm and 4 mm within each group at different study periods.

Point	Study Period	Groups		value
		Test	Control
Keratinized tissue thickness at 2 mm	Baseline	1.58 (±0.35)^B	1.54 (±0.40)^B	0.826 ns
	3 months	2.71(±0.33)^A	2.71(±0.42)^A	1.000 ns
	6 months	2.63 (±0.33)^A	2.50 (±0.36)^A	0.479 ns
