Results	Forty participants were enrolled. The periodontal treatment group (n = 20) received non-surgical periodontal therapy. The control group (n = 17) received only oral hygiene instructions. Changes in HbA1c in the periodontal treatment group were not significantly different with those in the control group at 3 and 6 months. Mean probing pocket depth, clinical attachment level, systemic oxidative stress balance and QOL significantly improved in the periodontal treatment group compared to the control group at 3 months. In the subgroup analysis (moderately poor control of diabetes), the decrease in HbA1c levels in the periodontal treatment group was significantly greater than that in the control group at 3 months.
