Insights
People with destructive periodontitis have a higher risk of cardiovascular disease (CVD). Periodontal therapy may help prevent or slow the progression of CVD, although more direct data is needed.
Area of Science:
- Periodontology
- Cardiology
- Public Health
Background:
- Cardiovascular disease (CVD) is a leading cause of mortality.
- Periodontitis, a common chronic inflammatory condition, is increasingly linked to CVD.
- Observational studies suggest a 1.3 to 2-fold increased risk of CVD in individuals with periodontitis.
Purpose of the Study:
- To explore the association between periodontal disease and cardiovascular disease.
- To review the biological plausibility and indirect evidence regarding the periodontal-cardiovascular link.
Main Methods:
- Review of observational studies on periodontitis and CVD prevalence.
- Examination of animal models investigating the impact of periodontal pathogens (e.g., Porphyromonas gingivalis) on atherosclerosis.
- Analysis of indirect data on the effects of periodontal therapy on cardiovascular risk markers.
Main Results:
- Consistent observational data show a significant association between periodontitis and increased CVD risk.
- Animal studies demonstrate that Porphyromonas gingivalis infection exacerbates atherosclerosis.
- Indirect evidence suggests mechanical periodontal therapy can reduce inflammatory markers like C-reactive protein, a surrogate CVD marker.
Conclusions:
- A consensus panel concluded that periodontal therapy may play a role in preventing or managing CVD.
- Patients and clinicians should be aware of the potential link between oral health and cardiovascular health.
- Further direct intervention studies are needed to confirm the impact of periodontal therapy on CVD outcomes.
Abstract:
Cardiovascular disease (CVD) and periodontitis are common chronic conditions, and the former remains a major contributor to human mortality. Recent attention has focused on a potential link between periodontal disease and CVD. Observational studies consistently indicate that people with destructive periodontitis may be 1.3 to 2 times more likely to have CVD. This association appears to be biologically plausible, and investigations in atherosclerosis animal models demonstrate larger atheroma sizes in animals infected with the periodontal pathogen, Porphyromonas gingivalis, compared with control animals. Although direct intervention data on the effects of periodontal therapy on CVD risk in patients are not currently available, indirect data suggest that mechanical periodontal therapy can decrease surrogate cardiovascular markers such as serum C-reactive protein. After a recent systematic review on the periodontal-cardiovascular link, a consensus panel concluded that patients and clinicians should be informed that periodontal therapy may prevent the onset or progression of CVD.

Regulation of the Cardiovascular System
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
