Periodontitis as a systemic inflammatory disorder - implications for cardiovascular and neurodegenerative diseases.

OBJECTIVE

Aim: Periodontitis is a chronic inflammatory condition associated with oral microbiome dysbiosis and the dominance of Gram-negative bacteria such as Porphyromonas gingivalis. It is characterized by progressive destruction of the supporting tissues of the tooth, leading to loss of connective tissue attachment, resorption of the alveolar bone, and, consequently to tooth loosening and loss. If left untreated, it leads to recurrent bacteremia and persistent systemic inflammation. The aim of this study is to discuss the mechanisms linking periodontitis to cardiovascular and neurodegenerative diseases.

Methods

A comprehensive literature review was conducted examining clinical studies, systematic reviews, and meta-analyses assessing the impact of periodontal disease on the development of cardiovascular and neurodegenerative diseases.

CONCLUSION

Conclusions

Chronic activation of the immune response, oxidative stress, and lipid metabolism disorders promote endothelial dysfunction and the progression of atherosclerosis, increasing the risk of cardiovascular events. At the same time, systemic inflammation can affect the permeability of the blood-brain barrier and exacerbate neuroinflammatory processes, promoting β-amyloid accumulation and the progression of Alzheimer's disease. Analysis of the literature indicates the significant, albeit complex, nature of these relationships, emphasizing the importance of prevention and treatment of periodontal disease as part of comprehensive patient care. The key in the approach to periodontal patients is an interdisciplinary perspective, integrating dentistry, cardiology, neurology, and geriatrics.
