The relationship between the quantitative measurement of streptococcus sanguinison dental plaque with the periodontal status of patients with coronary heart disease

Streptococcus sanguinis (S. sanguinis) is a common bacteria found in periodontal disease and coronary heart disease (CHD). This bacteria is suspected to have an important role in the relationship between both diseases through the blood stream. Objectives: To analyze the difference in thequantity of S. sanguinis on dental plaque between CHD and non-CHD patients. Methods: 66 CHD and 40 non-CHD patients were examined for periodontal status, and supragingival dental plaque was collected. A quantitative measurement of S. sanguinis was done with a real-time polymerase chain reaction. As the result showed that statistical analysis using the Mann-Whitney test was no significant difference between the number of S. sanguinis in CHD and non-CHD patients (p> 0.05). The Spearman test showed there was no correlation between the quantity of S. sanguinis with plaque accumulation, gingival bleeding, and pocket depth in CHD and non-CHD patients (p> 0.05). It was concluded that there is no difference between the quantity of S. sanguinis in CHD and non-CHD patients. There is no correlation between the quantity of S. Sanguinis and periodontal status in CHD and non-CHD patients.
