title: Crevicular fluid elastase levels in relation to periodontitis and metabolic control of diabetes.
abstract: The purpose of this study was to investigate the associations between gingival crevicular fluid (GCF) elastase levels, clinical measures of periodontal status, and metabolic control of diabetes in insulin dependent (type 1) diabetes (IDDM) and non-insulin dependent (type 2) diabetes (NIDDM) patients. Sixty patients were recruited from the Diabetes Center at the University of California in San Francisco. Thirty subjects were type 1 diabetics and 30 subjects were type 2 diabetics. Metabolic control was evaluated by glycosylatted hemoglobin (HbA1c) levels. Demographic information was obtained using a structured interview with the subjects. Clinical measurements and GCF samples were taken from the mesio-buccal surfaces of 2 premolars and 2 molars from the most diseased sextant. GCF elastase was determined by measurement of p-Nitroanalide resulting from hydrolysis of elastase specific peptide. Crevicular fluid elastase levels were significantly correlated with gingival index, bleeding index, probing depth and attachment level in both type 1 and type 2 diabetes groups (0.01 <p < 0.001). HbA1c levels were not correlated with clinical measurements and GCF elastase. The results suggest that GCF elastase. age and smoking are risk indicators for periodontitis in patients with diabetes mellitus, and periodontal status is not associated with the duration and metabolic control of diabetes.
