Aim:
To evaluate the effect of dental screening on the risk of cardiovascular disease (CVD) using data from a nationwide population-based cohort.
Materials And Methods:
This retrospective cohort study extracted data of 478,245 individuals aged 40-79 years who participated in a health screening programme during 2002-2003 from the National Health Insurance Service-National Health Screening Cohort. Based on screening experience, participants were classified into the non-screening, general screening only, and dental screening groups. Using Cox proportional hazard models, hazard ratios (HRs) were determined for major adverse cardiovascular events (MACE) during each group's 11-year follow-up period.
Results:
The risk of MACE in the dental screening group was 10% lower than that in the non-screening group (adjusted HR, 0.90; 95% confidence interval [CI], 0.87-0.93; p < .001) and 9% lower than that in the general screening only group (adjusted HR, 0.91; 95% CI, 0.89-0.94; p < .001).
Conclusions:
Dental screening was associated with a lower MACE risk; however, decreases in CVD-related healthcare utilization and costs were not clinically significant. The association could be attributed to healthy habits of participants in the dental screening group; nevertheless, it is conceivable that the improvement of oral health through dental screening influenced CVD prevention.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
