Investigate if there an association between chronic apical periodontitis and coronary artery disease
N=103 patients underwent coronary angiography (52 men, 51 women; mean age 62)
Prevalence of Chronic apical periodontitis (CAP)- 41.7 % and Coronary Artery Disease (CAD)- 65 % (Patients were categorized having CAD if they had coronary artery obstruction > 50 % in at least 1 coronary artery)

Patients with CAP had a 2.79 times higher risk of developing CAD
In these patients, the presence of CAP was independently associated with CAD
