Mean CAL	I	II	0.93488	0.1618	0.000	1.326	0.5438
		III	1.08697	0.1618	0.000	1.478	0.6959

Mean PISA	I	II	654.278	127.80	0.000	963.166	345.391

Group I: Well-controlled T2DM; Group II: Uncontrolled T2DM group without microvascular complications; Group III: Uncontrolled T2DM group with microvascular complications. There was no significant difference between uncontrolled T2DM without microvascular complications group and uncontrolled T2DM group with microvascular complications for mean probing pocket depth, clinical attachment loss, and periodontal inflamed surface area (P = 1.00). SE: Standard error; PPD: Probing pocket depth; CAL: Clinical attachment loss; PISA: Periodontal inflamed surface area; T2DM: Type 2 diabetes mellitus.
