Potential Association of Paraoxonase-1, Type 2 Diabetes Mellitus, and Periodontitis
2013
Background: The association between periodontitis and systemic diseases, including cardiovascular diseases and diabetes mellitus (DM), has been recognized repeatedly. Paraoxonase-1 (PON-1) is involved in the prevention of atherosclerosis, and decreased enzyme activity in patients with DM has been shown. The aim of this study is to investigate a possible correlation between decreased PON-1 activity and the association between impaired glucose metabolism or DM and periodontitis.Methods: PON-1 phenotype distribution and enzyme activities were characterized by measuring the hydrolysis of phenylacetate and paraoxon in serum samples of 87 patients with type 2 DM and 46 patients with pre-DM showing impaired fasting plasma glucose and/or impaired oral glucose tolerance. The control group comprised 64 individuals with normal fasting plasma glucose and normal glucose tolerance. Altogether, 154 study participants were available for complete clinical periodontal examination.Results: No difference in periodontitis pre...
