Periodontitis is a major chronic inflammatory disease associated with increased production of numerous proinflammatory cytokines, which leads to the destruction of the periodontal tissue and ultimately loss of teeth. Periodontitis has powerful and multiple influences on the occurrence and severity of systemic conditions and diseases, such as diabetes mellitus, cardiovascular disease and respiratory disease. Meanwhile, diabetes is associated with increased prevalence, severity and progression of periodontal disease. There is also abundant evidence showing that diabetes plays important etiological roles in periodontitis. High mobility group box 1 (HMGB1) was recently identified as a lethal mediator of severe sepsis and comprises a group of intracellular proteins that function as inflammatory cytokines when released into the extracellular milieu. From a clinical perspective, extracellular HMGB1 can cause multiple organ failure and contribute to the pathogenesis of sepsis, rheumatoid arthritis, cardiovascular disease and diabetes. We recently reported that HMGB1 expression in periodontal tissues was elevated in patients with severe periodontitis. In addition, the receptor for advanced glycation end-products (RAGE), a receptor for HMGB1, was strongly expressed in gingival tissues obtained from patients with type 2 diabetes and periodontitis compared with systemically healthy patients with chronic periodontitis patients. From these data, we hypothesize that HMGB1 might play a role in the development of diabetes-associated periodontitis.

For many years an association between diabetes and periodontitis has been suspected. In more recent times this relationship has been suggested to be bidirectional with each condition being able to influence the other. In this review the two-way relationship between diabetes and periodontitis is considered. For this narrative review a very broad search strategy of the literature was developed using both EMBASE and MEDLINE (via PubMed) databases. The reference lists from the selected papers were also scanned, and this provided an additional source of papers for inclusion and further assessment. The data available suggest that diabetes is a risk as well as a modifying factor for periodontitis. Individuals with diabetes are more likely to have periodontitis and with increased severity when diabetes is uncontrolled/poorly controlled. Possible mechanisms of how diabetes affects periodontitis include adipokine-mediated inflammation, neutrophil dysfunction, uncoupling of bone and advanced glycation end-products-receptor for advanced glycation end-products interaction. Evidence is accruing to support how periodontitis can affect diabetes and complications associated with diabetes. There is some evidence demonstrating that periodontal therapy can result in a moderate improvement in glycaemic control. Available evidence indicates that diabetes and peridontitis are intricately interrelated and that each condition has the capacity to influence clinical features of each other.
