Periodontal disease is associated with which diseases, with causation not clearly established?

• A. Coronary artery disease and cerebrovascular disease; causation is unclear
• B. Diabetes only
• C. No association with cardiovascular disease
• D. Periodontal disease prevents heart disease

Answer: (A)

Periodontal disease is a chronic inflammatory condition that can have systemic effects through circulating inflammatory mediators and occasional bacteremia. Large observational studies have shown associations with cardiovascular conditions such as coronary artery disease and cerebrovascular disease, but these findings do not prove that periodontal disease causes these heart and brain vessels problems. Confounding factors like smoking, age, and diabetes can influence both periodontal health and cardiovascular risk, making it difficult to establish a direct causal link. While the idea that treating periodontal disease could reduce cardiovascular events is plausible, current evidence does not confirm causation. Therefore, the strongest, most accurate statement is that periodontal disease is associated with coronary artery disease and cerebrovascular disease, with causation not clearly established. The other options either overstate the relationship or misstate the evidence.
