Periodontal Interventions and Cardiovascular Health

Periodontal disease, characterised by chronic inflammation of the supporting structures of the teeth, has emerged as a modifiable risk factor for cardiovascular disorders. Inflammation and microbial dysbiosis in periodontal tissues drive systemic immune activation, endothelial dysfunction and oxidative stress, all of which contribute to the development and progression of atherosclerosis and hypertension. Interventional strategies in dentistry, ranging from non-surgical debridement to adjunctive antimicrobial therapies, not only improve oral health but also yield measurable reductions in blood pressure and vascular inflammation. Emerging evidence highlights bidirectional communication between oral and systemic compartments, whereby changes in periodontal status can influence circulating inflammatory mediators and, conversely, systemic vascular health can affect periodontal healing. A holistic approach to patient care that integrates periodontal management into cardiovascular risk reduction protocols promises to enhance both oral and systemic outcomes on a global scale.

Periodontal Interventions and Cardiovascular Health publication trend

The graph below shows the total number of articles in periodontal interventions and cardiovascular health across all publications each year (not limited to Nature Index journals).

Technical terms

Periodontitis: A chronic inflammatory disease of the gums and supporting structures of the teeth, driven by microbial biofilms.

Atherosclerotic cardiovascular disease: A spectrum of conditions in which lipid-laden plaques develop within arterial walls, leading to ischaemic events.

Mendelian randomisation: An analytical approach using genetic variants as proxies for exposures to infer causal relationships in observational data.

Endothelial dysfunction: Impairment of the inner lining of blood vessels, marked by reduced vasodilatation and pro-inflammatory changes.

Dysbiosis: An imbalance in the composition or function of a microbial community, often leading to disease states.

Oral-gut microbial transmission: The migration and colonisation of oral microorganisms in the gastrointestinal tract, potentially influencing systemic health.
