This study included persons exposed to invasive dental treatment with a primary hospital discharge diagnosis of ischemic stroke or myocardial infarction from 2002 to 2006.
The rate of vascular events significantly increased in the first 4 weeks after invasive dental treatment (incidence ratio, 1.50) and gradually returned to the baseline rate within 6 months.
Invasive dental treatment may be associated with a transient increase in the risk for vascular events. However, the absolute risks are minimal, and the long-term benefits on vascular health will probably outweigh the short-lived adverse effects.
