 Aim: It has been suggested that periodontitis may be associated with increased oxidative stress. The objective of this study is to evaluate the possible differences in antioxidant status between chronic periodontitis (CP) and aggressive periodontitis (AP), by assessing the concentrations of antioxidants with total antioxidant status (TAS) and lipid peroxidation status in serum and gingival crevicular fluid (GCF) of these patients. Materials and methods: Forty-six patients with CP, 32 patients with AP, and 50 healthy controls were included in this study. The level of enzymatic antioxidant, superoxide dismutase (SOD), nonenzymatic antioxidant uric acid, and TAS with lipid peroxidation measured in serum and GCF of patients suffering from CP and AP were compared with the healthy controls. Results: The TAS is decreased and malondialdehyde (MDA) level is increased in both serum and GCF in CP and AP compared with healthy controls (p < 0.001). Superoxide dismutase activities in GCF and serum are found to be low in both the groups of periodontitis (p < 0.001). The uric acid levels are found to be inconsistent in GCF and serum in both the groups of periodontitis. Conclusion: Lipid peroxidation and TAS were affected at systemic level in serum and in GCF of the periodontal pockets, in CP and AP. Similar comments may be made for the decrease in SOD activities and inconsistent uric acid levels. Clinical significance: Increased oxidative stress may have a role in the pathogenesis of periodontal disease activity. © 2018 Jaypee Brothers Medical Publishers (P) Ltd.
