Abstract

Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans) is a Gram-negative, facultative anaerobic bacillus that causes periodontal diseases such as localized aggressive periodontitis (LAP) and. consequently. bone resorption. The potential virulence factors of this organism are powerful leukotoxin, lipopolysaccharide (LPS), cell surface-associated materials, enzymes, and less well-defined virulence factors that will modulate the activity of the host defenses. This organism can induce bone resorption by various virulence factors in periodontal disease. In this review article, we reviewed the pathogenic roles of A. actinomycetemcomitans in periodontal disease and the mechanism which can induce bone resorption. Findings from several studies indicate that the interaction between virulence factors and the host immune system's response often progress bone resorption in periodontal disease. In this organism, GroEL, DnaK, HtpG, LTX, CDT, LPS, and cell surface-associated materials produce cytokines when exposed to the immune system. The produced cytokines are the main cause of tissue destruction and bone resorption in A. actinomycetemcomitans inflammation in periodontal disease.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Fusobacterium nucleatum and A actinomycetemcomitans are well recognized in periodontal disease, and F nucleatum is noted for its role in the development of anaerobic microenvironments that facilitate the outgrowth of anaerobic periodontal pathogens.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
