[A survey on the periodontal status in type 2 diabetic patients].

Objective: To investigate the type 2 diabetic patient's periodontal condition and to analyze the influencing factors of periodontitis.
Methods: A total of 182 type 2 diabetic patients were included in the survey and requested to fill out a questionnaire, and their periodontal status was evaluated by measuring probing depth (PD), attachment level (AL), sulcus bleeding index (SBI), simplified oral hygiene index (OHI-S).
Results: The prevalence of periodontitis in this group of patients was 96.7% (176/182), including 20 patients with mild periodontitis, 156 with moderate to advanced periodontitis. The mean PD and AL of the 182 patients were (2.92 +/- 0.67) mm and (2.87 +/- 1.31) mm. At least one tooth was lost in 57.1% (104/182) of the patients. The factors related to periodontitis were age, gender, smoking, living in town or country, and 2 h plasma glucose of oral glucose tolerance test (OGTT). There was no relationship between the severity of periodontitis and education level. The majority of patients did not receive any periodontal therapy.
Conclusions: Periodontal status was bad in patients with type 2 diabetes. It is important to develop an education program on oral health for type 2 diabetic patients.
