BACKGROUND Chronic inflammation in periodontal disease has been suggested as a potential risk factor in Alzheimer's disease (AD). The purpose of this study was to examine serum antibody levels to bacteria of periodontal disease in participants who eventually converted to AD compared with the antibody levels in control subjects. METHODS Serum samples from(More)
Capture ELISAs with biotinylated monospecific antibodies were developed to detect both C-reactive protein (CRP) and haptoglobin (Hp) in serum of adult periodontitis (AP) patients and normal subjects. Each acute-phase reactant was significantly increased in serum from AP patients with CRP at 9.12 +/- 1.61 mg/l versus 2.17 +/- 0.41 mg/l (P < 0.001) and Hp at(More)
These studies determined the characteristics of tissue destruction in a murine abscess model elicited by mixed infection with the periodontopathogens Fusobacterium nucleatum and Porphyromonas gingivalis. The interbacterial effects of this synergism, the kinetics of the relationship of the bacterial interaction, and the characteristics of the bacteria(More)
One of the predominant polymicrobial infections of humans is expressed clinically as periodontal disease. Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia have been strongly implicated as members of a pathogenic consortium in the etiology of adult periodontitis. In this study we hypothesized that P. gingivalis, T. denticola, and T.(More)
BACKGROUND Tumor necrosis factor-alpha (TNF-alpha), C-telopeptide pyridinoline cross-links of type I collagen (ICTP), and receptor activator of nuclear factor-kappa B ligand (RANKL) have been associated with bone remodeling and periodontal tissue destruction. This study evaluated the level of these biomarkers in saliva with respect to periodontal disease(More)
Bacteria can indirectly affect the course of periodontal diseases by activating host cells to produce and release inflammatory mediators and cytokines. These mediators and cytokines manifest potent proinflammatory and catabolic activity and may play key roles in local amplification of the immune response as well as in periodontal tissue breakdown. This(More)
Eight juvenile periodontitis (JP) patients with progressing disease were evaluated for clinical, immunologic, and microbiologic features. Clinically, bleeding on probing, pocket depth, and attachment level were unrelated to progressing disease. Only Actinobacillus actinomycetemcomitans was related to a marked increase in attachment loss when examined on(More)
