Effect of non-surgical periodontal treatment on HbA1c levels in non-diabetic patients with chronic periodontitis in an Iranian population.

Non-surgical periodontal treatment resulted in a significant decrease in HbA1c levels in non-diabetic patients with chronic periodontitis. Although these levels did not reach the level of non-diabetic patients without periodontitis, it could be concluded that an improvement in the periodontal condition might lead to near-normal glycemic levels.
