THE EFFECTS OF CHRONIC PERIODONTITIS AND OBESITY ON TOTAL ANTIOXIDANT/OXIDANT STATUS AND OXIDATIVE STRESS INDEX.

ABSTRACT

Objective: Both obesity and periodontal diseases are significant diseases that affect the quality of life. Recent studies have focused on the relationship between obesity and periodontal disease. The aim of this study is to determine the pathophysiological relationship between obesity and periodontal disease by evaluating the clinical periodontal parameters and oxidative status. Subjects and Methods: The study included 80 individuals divided into four groups including 20 individuals in each group as following; periodontally healthy patients with normal weight, (NH), patients with chronic periodontitis and normal weight (NCP), periodontally healthy patients with obesity (OH) and patients with chronic periodontitis and obesity (OCP). Clinical periodontal parameters were recorded, and serum, saliva and gingival crevicular fluid (GCF) samples were obtained. Local and systemic levels of total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI) were assessed biochemically. Results: No statistically significant difference was found among the groups regarding TAS, TOS and OSI values in serum and saliva samples (p>0.05). GCF-TAS values in NH group were statistically significantly higher compared with other groups (p<0,05) . GCF TOS values increased in obese groups (OH, OCP) compared with non-obese groups (NH, NCP) (p<0.05). Our results suggest that obesity and chronic periodontitis do not effect oxidant/antioxidant levels in serum and saliva. Conclusions: Many factors such as daily living conditions of the individual, stress and nutritional habits TAS and TOS levels of the individual may affect oxidative stress parameters. However, these factors could not be standardized in the study.
