Abstract

Background: The relationship between periodontal disease and coronary artery disease has been suggested for more than a century. This study was carried out with the goal of surveying periodontal status in patients with coronary artery disease and understanding the relationship between periodontal status and severity of coronary artery disease. Subjects and methods: The study was conducted on two groups, including 50 patients with coronary artery disease, compared with control groups of the same age, sex. All subjects had a clinical dental examination to assess the periodontal indicators. Assessment of severity through coronary angiography in the group of diseases, thereby determining the relationships and correlations. Results: In the disease group, the average plaque index (1.96 ± 0.64), gingival index (1.49 ± 0.47) and clinical attachment loss (2.68 mm ± 1.12) was statistically significantly higher than the control group (p < 0.05). There was no difference in the periodontal pocket depth index between the two groups (p<0.05). The difference in the degree of gingivitis between the two groups was statistically significant (p<0.05). The average of periodontal indexes gradually increased according to the degrees of coronary artery stenosis (p<0.05).There is a significantly moderate positive correlation between the degree of coronary artery stenosis and the degree of periodontitis. Conclusions: There is an relationship between periodontal status and severity of coronary artery disease. Recognizing this relationship, we need to take measures to change people’s awareness about oral health with coronary heart disease through periodic dental examination and treatment.
