Pathogenesis of periodontitis.

M A Listgarten

    Journal of Clinical Periodontology
    |May 1, 1986

    Summary

    Periodontitis, an inflammatory gum disease, involves bacterial infections causing tissue destruction. Understanding bacterial translocation into tissues is crucial for distinguishing passive entry from active invasion in periodontitis.

    Area of Science:

    • Oral microbiology
    • Periodontal disease pathogenesis

    Background:

    • Periodontitis is an inflammatory condition characterized by progressive destruction of tooth-supporting tissues.
    • Its etiology involves complex microbial infections within the oral cavity, with over 300 bacterial species recognized.
    • The disease progresses in cycles of rapid tissue destruction and remission, leading to symmetrical alveolar bone loss and pocket formation.

    Purpose of the Study:

    • To elucidate the role of bacterial translocation in periodontitis.
    • To differentiate between passive bacterial entry and active invasion in periodontal tissues.

    Main Methods:

    • Review of existing reports on bacterial presence in periodontitis lesions.
    • Analysis of evidence for bacterial translocation, including bacteremia following oral activities.

    Main Results:

    • Bacterial cells are frequently found in the pocket walls of periodontitis lesions.
    • Translocation of bacteria from the pocket into periodontal tissues is common.
    • Bacteremia is frequently observed in periodontitis patients after routine activities.

    Conclusions:

    • Bacterial translocation into periodontal tissues is a common feature of periodontitis.
    • Distinguishing passive bacterial introduction from active invasion is critical for understanding disease pathology.
