AB  - Problem statement: There is increasing evidence that periodontal disease could play a role in the Progression of coronary heart disease although there are conflicting results about this association in the literature and the difference of used periodontal scoring systems among the studies might be a reason. The purpose of this study was to evaluate a specific scoring system Periodontal Index for Risk of Infectiousness (PIRI) in comparison with one of the classic periodontal indices Extent and Severity Index (ESI). Approach: A Total of 200 patients (100 candidate for bypass Surgery and 100 presumably healthy controls) were enrolled in this cross-sectional study age and sex matching were done for the two groups. PIRI and ESI were used to assess the periodontal status in both groups. Results: The average of attachment loss extent in CHD group was 94.77±13 and for severity: 4.47±1.36. The mean ESI scores was significantly higher in patients than in controls (p<0/0001) PIRI score showed that 87 patients in CHD group were in moderate group and 13 patients in severe group also PIRI scores between two groups, showed a significant difference (p = 0/01). A logistic regression model showed a association between both indices and coronary situation of patients. Conclusion: Our findings suggest that PIRI might be the best indicator for quantifying of subgingival surface exposure to microbial products and the risk of systemic consequences of periodontitis. Although it should be evaluated in other studies.
