Periodontitis: from microbial immune subversion to systemic inflammation

Open access
Hajishengallis, George·2015·Nature Reviews Immunology

Abstract

Periodontitis is a dysbiotic inflammatory disease with an adverse impact on systemic health. Recent studies have provided insights into the emergence and persistence of dysbiotic oral microbial communities that can mediate inflammatory pathology at local as well as distant sites. This Review discusses the mechanisms of microbial immune subversion that tip the balance from homeostasis to disease in oral or extra-oral sites.

  • Recent studies have highlighted that the mineralized structure of calculus may promote a dysbiotic shift in the microbial community, contributing to persistent inflammation and disease progression.

    “Recent studies have also highlighted that the mineralized structure of calculus may promote a dysbiotic shift in the microbial community, contributing to persistent inflammation and disease progression [4].”
  • Periodontal disease is caused by dysbiosis of subgingival microbial communities that adversely affects the host immune system such that it creates and maintains unmitigated inflammation in gingival and periodontal tissues, thus preventing immune subversion and tissue recovery.

    “Periodontal disease is caused by dysbiosis of subgingival microbial communities that adversely affects the host immune system such that it creates and maintains unmitigated inflammation in gingival and periodontal tissues, thus preventing immune subversion and tissue recovery.10”
  • Aspiration pneumonia is closely related to oral microorganisms due to the aspiration of oropharyngeal secretions.

    “It is speculated that aspiration pneumonia is also closely related to oral microorganisms due to the aspiration of oropharyngeal secretions (Hajishengallis, 2015).”

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.
