Clinical Comparison of the Volumetric Changes in Single Pontic Site Development through Connective Tissue Grafting Using Modified Pouch Technique versus Pouch Technique in the Maxillary Esthetic Zone: A Randomized Controlled Clinical Trial

Table 1

Mean and SD values for comparison in volumetric soft tissue changes (mm³) between both groups at different study periods.

Interval	Volumetric changes (mm^3) mean (±SD)		value
	Test (Modified pouch technique)	Control (Pouch technique)
Baseline	175.67 (±57.12)^B	145.19 (±65.76)^B	0.339 ns
3 months	203.44 (±50.65)^A	182.75 (±58.00)^A	0.460 ns
6 months	198.17 (±50.39)^A	173.51 (±57.84)^A	0.379 ns
-value	<0.001	<0.001

Means with different superscript letters within the same horizontal row are significantly different. ; significant () ns; nonsignificant ()
