- Aim We investigated the association between angiographically verified coronary artery disease (CAD) and subgingival Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola. Materials and Methods The cross-sectional study population (n = 445) comprised 171 (38.4%) patients with Stable CAD, 158 (35.5%) with acute coronary syndrome (ACS) and 116 (26.1%) with no significant CAD (No CAD). All patients participated in clinical and radiological oral health examinations. Pooled subgingival bacterial samples were analysed by checkerboard DNA–DNA hybridization assays. Results In all study groups, the presence of P. gingivalis, T. forsythia and T. denticola indicated a significant (p ≤ 0.001) linear association with the extent of alveolar bone loss (ABL), but A. actinomycetemcomitans did not (p = 0.074). With a threshold level of bacterial cells 1 × 105 A. actinomycetemcomitans was significantly more prevalent in the Stable CAD group (42.1%) compared to the No CAD group (30.2%) (p = 0.040). In a multi-adjusted logistic regression analysis using this threshold, A. actinomycetemcomitans positivity associated with Stable CAD (OR 1.83, 95% CI 1.00–3.35, p = 0.049), but its level or levels of other bacteria did not. Conclusions The presence of subgingival A. actinomycetemcomitans associates with an almost twofold risk of Stable CAD independently of alveolar bone loss.

- BACKGROUND: This cross-sectional study characterizes the association between subgingival bacterial profile and periodontal parameters in patients assigned to coronary angiography because of cardiologic problems, which may affect the oral microbiota.METHODS: Pooled subgingival bacterial samples were collected from 477 dentate individuals during the oral examinations, along with periodontal probing depth (PD) and assessments of bleeding on probing (BOP) and radiographic alveolar bone loss (ABL). The checkerboard DNA-DNA hybridization assay was used to determine the levels of 29 oral bacteria, which were divided into three bacterial complexes.RESULTS: All bacterial combinations from the etiologic bacterial group and each species from the red complex were significantly associated (P <0.001) with grade of ABL. The prevalence of the etiologic bacterial group and the level of each species were also associated strongly with the proportion of sites with PD 4 to 5 mm and ≥ 6 mm, BOP, and ABL, except Aggregatibacter actinomycetemcomitans. Levels of Gram-negative oral bacteria correlated significantly with those of Gram-positive species (r = 0.840, P <0.001). In multiple logistic regression analysis, the prevalence of the etiologic bacterial group, levels of Gram-negative bacteria and Treponema denticola, and the prevalence of Porphyromonas gingivalis and T. denticola associated significantly with ABL, whereas other bacterial complexes and levels of Gram-positive species did not.CONCLUSIONS: Although levels of Gram-negative and -positive species paralleled periodontal parameters, only the species considered etiologic were associated with ABL.
