The gingival immune response to periodontal pathogens in juvenile periodontitis

Oral Microbiology and Immunology, 1994
A gingival explant culture system was utilized to evaluate the reactivity of local immunoglobulins produced by juvenile periodontitis tissue. Gingival explant culture supernatant fluids were screened, via a standardized dot‐immunobinding assay, for antibodies reactive to: Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Prevotella ...

Prevalence of periodontal pathogens as predictor of the evolution of periodontal status

Odontology, 2016
The aim of this study was to determine the relationship between the prevalence of Porphyromonas gingivalis, its fimA genotypes, Aggregatibacter actinomycetemcomitans, Tannerella forsythia, and Treponema denticola and the evolution of periodontal health.

Periodontal conditions during the pregnancy associated with periodontal pathogens

Journal of Investigative and Clinical Dentistry, 2012
AbstractAimTo describe the bacterial associations in the periodontal pockets of pregnant women and to correlate the presence of Prevotella intermedia, Tannerella forsythia (T. forsythia), Treponema denticola (T. denticola), Aggregatibacter actinomycetemcomitans, and Porphyromona gingivalis (P.

QUANTITATIVE ANALYSIS OF PERIODONTAL PATHOGENS IN PERIODONTITIS AND GINGIVITIS.

Journal of biological regulators and homeostatic agents, 2015
Periodontal tissues surround the teeth and provide their attachment. Periodontal diseases include a mild and reversible form named gingivitis and periodontitis that is the main cause of tooth loss in adults. Gingivitis, that affects gums and coronal junctional epithelium, as well as periodontitis, that is characterized by loss of connective tissue ...

Subgingival Distribution of Periodontal Pathogenic Microorganisms in Adult Periodontitis

Journal of Periodontology, 1992
The association between specific plaque microorganisms and periodontal diseases has been the subject of much recent interest due to its potential importance in the diagnosis and classification of these diseases. In order to optimize microbiological tests in periodontal therapy, it is important to know how many subgingival plaque samples must be assayed

Direct microscopy of periodontal pathogens

Oral Microbiology and Immunology, 1986
Microscopic studies of the periodontal microbiota were among the first to demonstrate the existence of distinctive microbial populations in association with various states of periodontal disease and periodontal health. These findings led to further studies which indicated that conventional mechanical debridement is able to create shifts in the ...

Prevalence of periodontal pathogens in Brazilians with aggressive or chronic periodontitis

Journal of Clinical Periodontology, 2005
AbstractObjectives: Previous studies suggest differences between geographically and racially distinct populations in the prevalence of periodontopathic bacteria as well as greater periodontal destruction associated with infection by highly leucotoxic Actinobacillus actinomycetemcomitans.

Pathogenic Mechanisms in Periodontal Disease

Advances in Dental Research, 1994
Periodontal diseases have been considered as "infections" in which micro-organisms initiate and maintain the destructive inflammatory response. Host-mediated tissue destruction occurs via complement activation and the release of lysosomal enzymes, and connective tissue matrix metalloproteinases. Microbial enzymes may damage connective tissues directly,

Alcohol Consumption and Periodontitis: Quantification of Periodontal Pathogens and Cytokines

Journal of Periodontology, 2015
Background: There are few studies on periodontal status related to microbiologic and immunologic profiles among individuals not or occasionally using alcohol and those with alcohol dependence. The aim of this study is to determine the effect of alcohol consumption on the levels of subgingival periodontal pathogens and proinflammatory cytokines ...

Prevalence of periodontitis and suspected periodontal pathogens in families of adult periodontitis patients

Journal of Clinical Periodontology, 1994
Abstract The aim of the present study was to investigate the prevalence of periodontopathic microorganisms and periodontal destruction in the spouses and children of adult periodontitis patients. For this study, 24 families were selected on the basis of one parent with severe periodontal breakdown and the presence of Actinobacillus ...
