Pathogenicity of periodontal pathogens during pregnancy
American Journal of Obstetrics and Gynecology, 2005Objective: Periodontal disease may cause several complications of pregnancy, including fetal death. The purpose of this study was to investigate in sheep the effects of the intra-amniotic injection of lipopolysaccharide from 3 periodontopathic organisms and to compare these effects with those resulting from similar injection of Escherichia coli ...

CCL28 Effects on Periodontal Pathogens
Journal of Periodontology, 2007Background: Chemokines are small proteins that signal to and attract cells of the immune system; they are vital components in the modulation of immunity and wound healing. A newly described chemokine was reported to have antibacterial and antifungal activity.

Periodontal Pathogen Sialometabolic Activity in Periodontitis
2020Periodontitis is a common bacterially induced inflammatory condition that damages the tooth-supporting apparatus and negatively impacts the systemic health. It affects over 700 million people worldwide with an estimated economic burden totaling to $442 billion annually.

The gingival immune response to periodontal pathogens in juvenile periodontitis
Oral Microbiology and Immunology, 1994A 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, 2016The 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.

QUANTITATIVE ANALYSIS OF PERIODONTAL PATHOGENS IN PERIODONTITIS AND GINGIVITIS.
Journal of biological regulators and homeostatic agents, 2015Periodontal 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 ...

Periodontal conditions during the pregnancy associated with periodontal pathogens
Journal of Investigative and Clinical Dentistry, 2012AbstractAimTo 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.

Direct microscopy of periodontal pathogens
Oral Microbiology and Immunology, 1986Microscopic 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 ...

Subgingival Distribution of Periodontal Pathogenic Microorganisms in Adult Periodontitis
Journal of Periodontology, 1992The 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

Pathogenic Mechanisms in Periodontal Disease
Advances in Dental Research, 1994Periodontal 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,
