Significant Immune Findings in Periodontal Diseases

Periodontal diseases are associated with various immune responses that can influence disease progression and severity. Understanding these immune findings is crucial for diagnosing and managing different forms of periodontal disease.

Immune Findings in Specific Periodontal Diseases

1. Acute Necrotizing Ulcerative Gingivitis (ANUG):

   • Findings:
     • PMN (Polymorphonuclear neutrophil) chemotactic defect: This defect impairs the ability of neutrophils to migrate to the site of infection, compromising the immune response.
     • Elevated antibody titres to Prevotella intermedia and intermediate-sized spirochetes: Indicates an immune response to specific pathogens associated with the disease.

2. Pregnancy Gingivitis:

   • Findings:
     • No significant immune findings reported: While pregnancy gingivitis is common, it does not show distinct immune abnormalities compared to other forms of periodontal disease.

3. Adult Periodontitis:

   • Findings:
     • Elevated antibody titres to Porphyromonas gingivalis and other periodontopathogens: Suggests a heightened immune response to these specific bacteria.
     • Occurrence of immune complexes in tissues: Indicates an immune reaction that may contribute to tissue damage.
     • Immediate hypersensitivity to gingival bacteria: Reflects an exaggerated immune response to bacterial antigens.
     • Cell-mediated immunity to gingival bacteria: Suggests involvement of T-cells in the immune response against periodontal pathogens.

4. Juvenile Periodontitis:

   • Localized Juvenile Periodontitis (LJP):
     • Findings:
       • PMN chemotactic defect and depressed phagocytosis: Impairs the ability of neutrophils to respond effectively to bacterial invasion.
       • Elevated antibody titres to Actinobacillus actinomycetemcomitans: Indicates an immune response to this specific pathogen.
   • Generalized Juvenile Periodontitis (GJP):
     • Findings:
       • PMN chemotactic defect and depressed phagocytosis: Similar to LJP, indicating a compromised immune response.
       • Elevated antibody titres to Porphyromonas gingivalis: Suggests an immune response to this pathogen.

5. Prepubertal Periodontitis:

   • Findings:
     • PMN chemotactic defect and depressed phagocytosis: Indicates impaired neutrophil function.
     • Elevated antibody titres to Actinobacillus actinomycetemcomitans: Suggests an immune response to this pathogen.

6. Rapid Periodontitis:

   • Findings:
     • Suppressed or enhanced PMN or monocyte chemotaxis: Indicates variability in immune response among individuals.
     • Elevated antibody titres to several gram-negative bacteria: Reflects an immune response to multiple pathogens.

7. Refractory Periodontitis:

   • Findings:
     • Reduced PMN chemotaxis: Indicates impaired neutrophil migration, which may contribute to disease persistence despite treatment.

8. Desquamative Gingivitis:

   • Findings:
     • Diagnostic or characteristic immunopathology in two-thirds of cases: Suggests an underlying immune mechanism.
     • Autoimmune etiology in cases resulting from pemphigus and pemphigoid: Indicates that some cases may be due to autoimmune processes affecting the gingival tissue.
