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 ...

Risk Indicators for Harboring Periodontal Pathogens

Journal of Periodontology, 1998
The risk for harboring 6 putative periodontal pathogens in 4 selected periodontal pockets, in whole saliva, or in either site (i.e., orally) was determined in 52 Caucasians, 49 African‐Americans, 48 Asian‐Americans, and 50 Hispanics living in Los Angeles.

Identification of Periodontal Pathogens in Atheromatous Plaques

Journal of Periodontology, 2000
Background: Recent studies suggest that chronic infections including those associated with periodontitis increase the risk for coronary vascular disease (CVD) and stroke. We hypothesize that oral microorganisms including periodontal bacterial pathogens enter the blood stream during transient bacteremias where they may play a role in the development and

Immunological assays for putative periodontal pathogens

Oral Microbiology and Immunology, 1986
Immunological tests including immunofluorescence microscopy, latex agglutination, flow cytometry, and enzyme‐linked immunosorbent assays are being developed for the detection of carcinogenic microorganisms and periodontal pathogens. In the present study, indirect immunofluorescence microscopy was used to examine two hundred eighty‐three subjects for ...

DNA probe detection of periodontal pathogens

Oral Microbiology and Immunology, 1986
The technology for hybridization of nucleic acids using isotopically labeled whole genomic or species‐specific cloned deoxyribonucleic acid (DNA) probes for Actinobacillus actinomycetemcomitans, Bacteroides intermedius and Bacleroides gingivulis can be used to detect as few as 102 cells of these periodontal pathogens. The sensitivity and specificity of
