Objectives: Increased levels of reactive oxygen species lead to oxidative stress. Recent data suggest increased lipid peroxidation (LPO) levels and oxidative stress in periodontitis. Malondialdehyde (MDA), a significant LPO product, increases in oxidative stress. In this study, MDA levels and total oxidant status (TOS) in serum, saliva and gingival crevicular fluid (GCF) were investigated in patients with chronic periodontitis (CP).
