Purpose of ReviewPeriodontitis and cardiovascular diseases are both inflammatory conditions. Recent epidemiological studies have associated the effects of periodontitis on cardiovascular disease (CVD) progression. This review aims to summarize the relationship between those two conditions.Recent FindingsAlthough there is no evidence of a causal relationship, an association between the two conditions is apparent. The potential factors include bacterial pathway, inflammation, and genetics. Periodontal bacteria affect endothelial cells through interactions that aggravate the atherogenic process. Ulcerated periodontium produces cytokines which increase the production of acute-phase proteins that have been associated with cardiovascular events. Genetic studies have demonstrated the presence of risk alleles in the genes ANRIL and CAMTA1/VAMP3 that are shared between these two diseases.SummaryThis review discusses the current understanding of CVD pathogenesis, underlying mechanisms of periodontitis in CVD, and effects of periodontal therapy on CVD, and provides guidelines for treating patients with CVD risks in respect to periodontal disease.
