Methods Patients with periodontitis associated with type 2 diabetes，patients with simple periodontitis and healthy controls were selected. They were requested to fill a questionnaire;periodontal status was evaluated by measuring probing depth （PD），clinical attachment level （CAL），sulcus bleeding index（SBI），simplified oral hygiene index（OHI-S） and tooth mobility（TM）. Taking fasting venous blood and the intravenous blood of research object 2 hours after taking 75g glucose orally. Then，serum biochemical indicators were analyzed by automatic biochemical analyzer. Results The prevalence of periodontitis was 96.7% in type 2 diabetic patients. Excluding the impact of sex， age， place of residence and education level，the probing depth and clinical attachment loss of periodontitis associated with type 2 diabetes group was significantly higher than group of simple periodontitis.
