Context: Oxidative stress is associated with the pathogenesis of many systemic diseases including chronic periodontitis. Periodontal pathogen activated neutrophils liberate the reactive oxygen species (ROS), which causes the destruction of periodontal tissues. Antioxidants modulate the ROS production and inhibit the tissue destruction. Aim: We aimed to evaluate the oxidative stress marker malondialdehyde (MDA) in chronic periodontitis patients following scaling and root planing (SRP) after systemic lycopene supplementation. Materials and Methods: This was an interventional single arm study. Twenty systemically healthy patients with chronic periodontitis were recruited. Clinical parameters modified gingival index, probing depth, clinical attachment loss were recorded, and serum MDA levels were assessed by thiobarbituric acid reactive substances assay. Patients were supplemented with 8 mg lycopene daily for 2 months following SRP treatment. All the parameters were assessed at pretreatment and 2 months and 6 months posttreatment. Results: From pretreatment to posttreatment at 2 months, the mean values of all parameters were reduced. While from 2 to 6 months when lycopene was not administered, an increase in the mean values of all the parameters was observed; however, these values were still below baseline values. Conclusion: There was a reduction in oxidative stress and improvement in clinical parameters following systemic antioxidant therapy along with SRP, which was maintained up to 4 months after discontinuation of lycopene treatment.
