It has been reported that an increased levels of inflammatory biomarkers such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and c-reactive protein (CRP) are elevated in diabetic individuals and may induce periodontitis [27, 28] It has also been suggested that advanced glycation end products (AGEs), which are produced during DM, interact with receptors of advanced glycation end products (RAGEs) in the periodontal tissues to cause oxidative damage and worsen periodontal disease [29, 30]. This evidence concerns the gene IL6 and periodontal disorder.
