Saliva White Blood Cells: A Potential Biomarker for Heart Disease

A recent study by Canadian researchers suggests that elevated white blood cell counts in saliva, even among young and seemingly healthy individuals, may serve as an early warning sign of cardiovascular disease. Gum disease and oral inflammation can impact blood vessels around the teeth, potentially affecting heart health. The study proposes the development of a simple mouth rinse test to assess heart disease risk during routine checkups. While the research is based on a small sample size, it underscores the potential link between oral health and heart function, emphasizing the importance of dental hygiene and regular dental visits.
