Obesity and oxidative stress in patients with different periodontal status: a case-control study.

Background And Objective: Obesity has become an important global health concern as obesity-associated adiposity is supposedly related to systemic immunologic and inflammatory alterations. The aim of this study was to evaluate the effects of obesity on periodontally healthy and diseased tissue according to the changes in malondialdehyde (MDA), protein carbonyl (PC) and total antioxidant capacity (TAOC) levels in gingival crevicular fluid as biomarkers of oxidative stress (OS).

Material And Methods: The study sample comprised systemically healthy normal-weight (n = 45) and obese (n = 48) adults.
