Overview
In this study aimed to investigate the effect of nutrition on periodontal status in individuals diagnosed with obesity and without any other systemic disease, and to investigate the relationship between DII and periodontal disease risk. A total of 200 participants will be included in the study. Participants' overall daily Dietary Inflammatory Index (DII) scores will be calculated. The obtained scores will be divided into four groups, from low to high: Q1 (n=50), Q2 (n=50), Q3 (n=50), and Q4 (n=50). According to the DII, groups Q1 and Q2, which include lower scores, represent individuals on an anti-inflammatory diet, while groups Q3 and Q4, which include higher scores, represent individuals on a pro-inflammatory diet. Interleukin (IL)-1β, IL-10, total oxidant status (TOS), and total antioxidant status (TAS) were collected from gingival crevicular fluid (GCF) and serum samples. The levels of biomarkers such as malondialdehyde (MDA), glutathione (GSH), leptin, adiponectin, tumor necrosis factor (TNF)-α and C-reactive protein (CRP) from serum samples alone will be analyzed by ELISA method at the Recep Tayyip Erdoğan University Medical Biochemistry Laboratory.
