Tooth Scaling Associated With Decreased Cardiovascular Disease
Recent study results showed an association between regular tooth scaling and a decreased risk of future cardiovascular events. “Poor oral hygiene has been associated with an increased risk for cardiovascular disease,” authors of the study wrote. “However, the association between preventive dentistry and cardiovascular risk reduction has remained undetermined.” Using a nationwide, population-based study and a prospective cohort design, the research team aimed to “investigate the association between tooth scaling and the risk of cardiovascular events.”
H-B. Leu, MD, of Taipei Veterans General Hospital, and colleagues selected participants aged at least 50 years from the nationally representative Taiwan National Health Insurance Research Database. Authors of the study, published in the American Journal of Medicine, used 10,887 subjects who had received full-mouth or localized tooth scaling and compared them to 10,989 subjects who had not received any tooth scaling. The group of participants exposed to the scaling was then propensity-score matched to the nonexposed group. After following the subjects for an average period of seven years, the authors reported finding that the group that had undergone tooth scaling had a lower incidence of acute myocardial infarction, stroke, and total cardiovascular events.
“Furthermore, when compared with the nonexposed group, increasing frequency of tooth scaling correlated with a higher risk reduction of acute myocardial infarction, stroke, and total cardiovascular events,” authors wrote.
