    Gingival bleeding is linked to specific inflammatory cells in the connective tissue, not always dominated by plasma cells. This finding impacts diagnosing periodontal disease activity.

    Area of Science:

    • Oral biology
    • Periodontology
    • Immunohistochemistry

    Background:

    • Gingival bleeding is a common clinical sign in periodontal health assessments.
    • Understanding the cellular basis of gingival bleeding is crucial for accurate diagnosis of periodontal disease.

    Purpose of the Study:

    • To characterize the cellular composition of mid-interproximal gingival tissue.
    • To correlate specific cell populations with the presence or absence of gingival bleeding.

    Main Methods:

    • Obtained 30 interproximal gingival biopsies (15 bleeding, 15 non-bleeding).
    • Performed light microscopic evaluation and morphometric analysis of tissue components.

    Main Results:

    • Bleeding sites exhibited inflammatory lesions in the mid-interproximal connective tissue.

  • The inflammatory infiltrate primarily comprised mononuclear cells (lymphocytes, macrophages, monocytes).
  • Plasma cells and polymorphonuclear leukocytes were present in smaller proportions.

    • Conclusions:

    • Interproximal gingival bleeding can be associated with an inflammatory infiltrate not solely dominated by plasma cells.
    • The cellular profile of gingival bleeding warrants consideration in assessing periodontal disease activity.
