RESUMO

The aim of this study was to evaluate the relationship between periodontal disease and obstructive atherosclerotic coronary disease (OACD) in patients with indication for percutaneous transluminal coronary angioplasty (PTCA). Eighteen patients with diagnose of periodontal disease and OACD were selected for this study. After thorough periodontal examination subgengival biofilm samples were collected in periodontal pockets with probing depth _ 5mm. The balloons used to crush the atherosclerotic plaques during the angioplasty procedure were collected. Bacteria found in biofilm and balloons were identified using polymerase chain reaction (PCR) assays. Bacteria from periodontal pockets were compared with the microorganisms detected in the atherosclerotic plaques obtained from the same patient and with the pure DNA of periodontal pathogens (Aggregatibacter actinomycetencomitans - Aa, Porphyromonas ginginvalis - Pg, Prevotella intermédia - Pi, Tannerella forsythensis - Tf). After the microbiological analysis it was observed the presence of Pg in 11.1% of the samples, Tf in 38.9% of the balloons. None of the balloons were positive for the presence of Pi and Aa. After statistic analysis for McNemar test, with significance level of 5%, and within the limits of this study, it can be concluded that even though two periodontal pathogens (Porphyromonas gingivalis e Tannerella forsythensis) were found both in the balloons and subgingival biofilms, the correlation between the samples was not significant, thus not allowing the assertive that there is a causal relationship between periodontal disease and obstructive atherosclerotic coronary disease
