OBJECTIVE Several studies have shown that periodontitis is a risk factor for cardiovascular diseases. There is an association between inflammation and endothelial dysfunction. The purpose of this study was to evaluate endothelial function in patients with coronary artery disease (CAD) who had periodontitis. METHODS AND RESULTS We evaluated forearm blood flow (FBF) responses to acetylcholine (...

Our aim was to investigate the value of salivary concentrations of four major periodontal pathogens and their combination in diagnostics of periodontitis. The Parogene study included 462 dentate subjects (mean age 62.9 ± 9.2 years) with coronary artery disease (CAD) diagnosis who underwent an extensive clinical and radiographic oral examination. Salivary levels of four major periodontal bacteri...

BACKGROUND Periodontitis is a common, chronic inflammatory disease. Although n-3 fatty acids have anti-inflammatory properties, it is unclear whether n-3 fatty acids can treat or prevent periodontitis. METHOD We studied 9,182 adults aged 20 years and older who participated in the National Health and Nutrition Examination Survey between 1999 and 2004. Periodontitis was assessed by dental exam ...

This study investigated if chronic obstructive pulmonary disease (COPD) is correlated with periodontitis via periodontal microbiota and if certain bacteria affect periodontitis as well as COPD. Moreover, the study investigated whether suffering from COPD is associated with a decrease in the richness and diversity of periodontal microbiota. Subgingival plaque was obtained from 105 patients. Bact...

UNLABELLED Phagocytosis by neutrophils and monocytes constitutes the main defense mechanism against bacterial challenges in periodontitis. Phagocytosis by neutrophils has already been evaluated, whereas phagocytic function of monocytes has hardly been addressed so far. OBJECTIVES The aim of this study was to assess phagocytosis by neutrophils and monocytes in periodontitis. MATERIAL AND MET...

BACKGROUND Porphyromonas gingivalis, a black-pigmented, gram-negative anaerobe, is found in periodontitis lesions and its presence in subgingival plaque significantly increases the risk for periodontitis. We have previously shown that patients with aggressive forms of periodontitis that are seropositive for P. gingivalis have less attachment loss than those that are seronegative. This suggests ...

Periodontitis is a chronic inflammatory disease that affects the interface of teeth and surrounding tissues. Gingival crevicular fluid (GCF) is an exudate of the periodontal tissues and can be collected from the gap between the tooth and gum (gingival sulcus or periodontal pocket) with paper strips. Testing of GCF is a low-cost and minimally invasive procedure. In a variety of diseases, microRN...

OBJECTIVE There are conflicting reports in the past literature documenting the tendency of anemia in patients with periodontitis. Hence, this study was undertaken to assess whether periodontitis may cause an anemic state, by evaluating and comparing the red blood cell count, levels of hemoglobin, hematocrit, erythrocyte sedimentation rate (ESR), serum iron and serum ferritin between subjects wi...

BACKGROUND AND AIMS Recent epidemiological studies have shown that individuals with periodontitis have a significantly higher risk of developing coronary heart disease, which might be attributed to the complex microbiota in the dental plaque. Periodontopathogens have been reported as risk factors for cardiovascular disease. This study evaluated association of chronic periodontitis and periodont...

PURPOSE In longitudinal studies, the onset of the index condition (e.g. exposure) does not always coincide with the start of a study's observation period, leading to the possibility of bias in estimation that derives from studying prevalent exposure rather than new exposure. We investigate the possible role of this bias in the relationship between periodontitis progression and coronary heart di...
