Association of salivary lipid peroxidation levels, antioxidant enzymes, and chronic periodontitis.
This study assessed the activities of antioxidant enzymes superoxide dismutase (SOD), glutathione reductase (GR), and catalase (CAT) and free radical damage marker malondialdehyde (MDA) levels in saliva of 30 patients with chronic periodontitis (CP) compared to 30 healthy controls by spectrophotometry. MDA levels were significantly elevated in the CP group, whereas the SOD, CAT, and GR activities were significantly reduced compared to healthy controls. MDA levels demonstrated a significant direct correlation with all periodontal parameters, whereas all antioxidant enzymes studied (SOD, CAT, and GR) showed an inverse correlation. These findings support the idea that oxidative stress has a role in periodontal disease pathogenesis.
