Exploring the Association Between Periodontal Disease and Cardiac Disease: Implications for Cardiac Patient Assessment and Periodontal Treatment


Periodontal disease, a chronic inflammatory condition affecting the supporting structures of the teeth, has been increasingly recognized as a potential risk factor for cardiac disease. This scientific article aims to provide an in-depth analysis of the association between periodontal disease and cardiac disease, emphasizing the importance of assessing periodontal health in cardiac patients. Furthermore, it highlights the role of periodontists in the treatment and management of periodontal disease in this patient population. The evidence presented underscores the need for interdisciplinary collaboration between cardiologists and periodontists to optimize patient care and improve overall health outcomes.

1. Introduction:

Periodontal disease and cardiac disease are prevalent chronic conditions with significant implications for public health. Research over the past decades has demonstrated a potential link between these two conditions. Periodontal disease, characterized by inflammation and destruction of the periodontal tissues, has been associated with an increased risk of developing or exacerbating cardiac disease. This article aims to explore the scientific evidence supporting this association, emphasizing the importance of periodontal assessment and treatment in cardiac patients.

2. Periodontal Disease and Cardiac Disease: Shared Risk Factors:

Both periodontal disease and cardiac disease share common risk factors, such as smoking, diabetes, obesity, and systemic inflammation. Chronic inflammation, a hallmark of periodontal disease, may contribute to the development and progression of cardiac disease by promoting endothelial dysfunction, atherosclerosis, and thrombosis. Furthermore, periodontal pathogens and their byproducts can disseminate systemically, potentially affecting distant organs and contributing to systemic inflammation and endothelial dysfunction.

3. Mechanisms Underlying the Periodontal-Cardiac Connection:

Multiple mechanisms have been proposed to explain the association between periodontal disease and cardiac disease. These include the direct entry of periodontal pathogens into the bloodstream, triggering an inflammatory response in the vascular endothelium, and the release of inflammatory mediators that promote atherosclerotic plaque formation and destabilization. Additionally, chronic periodontal infection may contribute to systemic inflammation, leading to endothelial dysfunction and an increased risk of adverse cardiovascular events.

4. Epidemiological Evidence:

Epidemiological studies have consistently shown an association between periodontal disease and cardiac disease, including coronary artery disease, myocardial infarction, and stroke. A systematic review and meta-analysis of observational studies revealed a significant association between periodontal disease and increased risk of cardiovascular events. These findings underscore the importance of recognizing periodontal disease as a potential modifiable risk factor for cardiac disease.

5. Cardiac Patient Assessment and Periodontal Treatment:

Given the established association between periodontal disease and cardiac disease, it is crucial to assess periodontal health in cardiac patients. Cardiologists should collaborate with periodontists to identify patients who may benefit from comprehensive periodontal evaluation and treatment. Periodontal therapy, including scaling and root planing, adjunctive antimicrobial therapy, and periodontal surgery when indicated, aims to control periodontal inflammation and reduce the burden of periodontal pathogens. Such interventions have shown promise in improving periodontal health and may potentially contribute to better cardiovascular outcomes.

6. Interdisciplinary Collaboration for Optimal Patient Care:

Interdisciplinary collaboration between cardiologists and periodontists is essential to provide comprehensive care to cardiac patients. By incorporating periodontal assessment and treatment into the management plan, healthcare providers can address both cardiac and periodontal disease, potentially improving overall health outcomes and quality of life for patients.


The association between periodontal disease and cardiac disease highlights the need for comprehensive patient care that addresses both conditions. Cardiac patients should undergo periodontal assessment.
