Abstract
OBJECTIVE
The relationship between dental caries and stroke remains inconclusive. The aim of this study is to investigate whether different severities of dental caries affect the risk of stroke.
METHODS
This retrospective cohort study was conducted using the 2000-2013 Taiwan National Health Insurance Database. We selected 23,662 patients with advanced/severe dental caries and 23,662 patients with incipient/moderate dental caries between 2000 and 2006. These patients were followed to the occurrence of stroke or to the end of the study in 2013. Hazard ratios (HRs) and 95% confidence intervals (CIs) derived from the Cox proportional hazards models were calculated to assess the association between severity of dental caries and the risk of stroke.
RESULTS
The advanced/severe dental caries group had a significantly higher risk of stroke compared with incipient/moderate dental caries group (adjusted HR, 1.16; 95% CI, 1.03-1.31). Stratified analyses showed that advanced/severe dental caries was positively associated with the risk of ischemic stroke in patients aged ≥40 years and with the risk of hemorrhagic stroke in patients aged <40 years.
CONCLUSION
There is a severity-dependent association between dental caries and stroke in an Asian population.
