Poor oral hygiene can provoke transient bacteremia and systemic inflammation, a mediator of atrial fibrillation and heart failure..
.. In multivariate analysis after adjusting age, sex, socioeconomic status, regular exercise, alcohol consumption, body mass index, hypertension, diabetes, dyslipidemia, current smoking, renal disease, history of cancer, systolic blood pressure, blood and urine laboratory findings, frequent tooth brushing (≥3 times/day) was significantly associated with attenuated risk of atrial fibrillation (hazard ratio: 0.90, 95% confidence interval (0.83–0.98)) and heart failure (0.88, (0.82–0.94)). Professional dental cleaning was negatively (0.93, (0.88–0.99)), while number of missing teeth ≥22 was positively (1.32, (1.11–1.56)) associated with risk of heart failure.
Improved oral hygiene care was associated with decreased risk of atrial fibrillation and heart failure. Healthier oral hygiene by frequent tooth brushing and professional dental cleaning may reduce risk of atrial fibrillation and heart failure
