Periodontal Disease and Cardiovascular Risk Factors

Various studies have suggested a bidirectional association between periodontal disease and systemic health conditions. Periodontitis is caused by polymicrobial infection, and it affects 7 - 11% of adults worldwide in an age-dependent manner. Besides its local manifestations, including gingival inflammation, periodontal pocket formation, and alveolar bone loss, periodontitis is linked to several systemic conditions. Emerging evidence points to associations with obesity, diabetes, Cardiovascular (CV) Disease (CVD), chronic renal disease, inflammatory bowel disease, respiratory diseases, rheumatoid arthritis, unfavorable pregnancy outcomes, specific cancers, neurodegenerative disorders, psychological diseases, and autoimmune disorders. These links seem to be mediated by 3 main mechanisms: dysbiotic oral biofilms, chronic low-grade systemic inflammation, and the spreading of periodontal pathogenic microbes throughout the body. The pathophysiologic mechanisms involved comprise high concentrations of pro-inflammatory cytokines (e.g., tumor necrosis factor alpha, interleukin 6), increased C-reactive protein, worsened immune function, oxidative stress, and molecular mimicry. Certain periodontal pathogenic microorganisms (e.g., Porphyromonas gingivalis) play a role in triggering and maintaining systemic inflammatory responses. Importantly, management of periodontitis has led to improvements in various systemic conditions, underscoring the clinical importance of these links. Thus, periodontitis represents more than a local oral disease; it significantly contributes to the overall systemic inflammatory burden, with implications for general and cardiovascular health. Therefore, an organized multidisciplinary approach for the prevention, early detection, and optimal management of periodontal disease is essential for improving both cardiovascular and overall patient outcomes. In this respect, healthcare providers should regard oral health as a crucial and integral component of systemic health.
