In a nutshell
This paper studied whether gingival (gum) inflammation increases the risk for stroke.
Some background
Gingival inflammation, also known as gingivitis, refers to redness and swelling of the gum tissue in the mouth. Gingivitis is a response to infection in the mouth. This can be reduced with good oral hygiene. Chronic infections of the gums have been shown to be involved in the development of heart disease. Thus, it is suggested that gingivitis would be associated with stroke (not enough blood supply to the brain).
Methods & findings
In total 1,676 individuals (838 men and 838 women) were studied. They underwent a comprehensive investigation of the mouth, teeth and gums. They were followed for 26 years.
Overall, 2.3% of participants had a stroke. Smoking was more common among participants who had a stroke than participants who did not have a stroke. Gingival inflammation was more severe among participants who had a stroke than participants who did not have a stroke. Participants with gingival inflammation were 2.2 times more at risk of stroke. Dental plaques (mass of bacteria) were more common among participants who had a stroke than participants who did not have a stroke.
The bottom line
The authors concluded that gingival inflammation was associated with stroke, highlighting the importance of oral hygiene.
