Objective: Chronic periodontitis (CP) is a common, chronic inflammatory disease initiated by bacteria, which has an increased prevalence and severity in patients with type 2 diabetes mellitus (t2 DM). A variety of reactive oxygen species are able to cause direct damage to proteins, deoxyribonucleic acid, carbohydrates and lipids. Lipid peroxidation is always combined with the formation of reactive aldehydes like 4-Hydroxy-2-nonenal (HNE). The purpose of this study was to determine the presence of the HNE-His adducts levels in serum and gingival crevicular fluid (GCF) in t2 DM among CP subjects and to find an association, if any. Materials and Methods: A total of 40 subjects (20 males and 20 females) were selected based on their clinical parameters into three groups: Group 1 (10 healthy), Group 2 (15 subjects, CP without t2 DM), Group 3 (15 subjects, CP with t2 DM). Serum and GCF samples were collected to estimate the levels of the HNE-His adducts by the enzyme linked immunosorbent assay. Results: The mean HNE-His adducts concentration both in serum and GCF was highest for Group 3 followed by Group 2 and least in Group 1. Conclusions: All samples in each group tested positive for HNE-His adducts assay. Serum and GCF HNE-His adducts concentration both in t2 DM with CP and non-diabetic CP subjects were higher than the healthy controls. Further large scale longitudinal studies should be carried out to confirm positive correlations.
