Objective The objective of the study is to examine the connection between oral status and the extent of coronary artery disease (CAD), which is diagnosed by angiography. Background Periodontitis and tooth loss have been linked to atherosclerosis and CAD in previous studies. However, no distinct connection was revealed due to the diversity of the results and the variety of diagnostic methods. To provide a more consistent data pool and stronger evidence, there is a need for studies with standard measurements and diagnostic criteria. Methods 309 patients, who consulted to Ankara University, Faculty of Medicine, Department of Cardiology and had coronary angiography, were enrolled to this study. Individuals were grouped based on their coronary angiography results, as CAD (+) (n = 233) and CAD (-) (n = 76). Studied parameters included cardiovascular risk factors, plaque index (PI), remaining teeth count, bleeding on probing (BOP), and probing pocket depth (PPD). Periapical radiographs were taken from teeth with >= 4 mm PPD. Oral status was categorized as periodontally healthy subjects/patients with gingivitis (Group 1), patients with periodontitis (Group 2), and edentulous subjects (Group 3). Results PI (P < 0.001), PPD (P = 0.001), BOP (P = 0.004), the number of patients with less than 10 teeth (P = 0.014), and edentulism (P = 0.009) were significantly higher in CAD (+) patients, who were mostly older (P < 0.001) and male (P < 0.001). Multivariate logistic regression analysis revealed that Group 2 (odds ratio = 2.48, 95% confidence interval = 1.24-4.95,P = 0.010) and Group 3 (odds ratio = 2.01, 95% confidence interval = 1.14-5.17,P = 0.040) were highly associated with CAD. Two and three stenosed vessels were significantly higher in Groups 2 and 3 compared to Group 1 (P = 0.003). Conclusions It was found that both edentulism and periodontitis were related to CAD.
