Summary
Actinobacillus actinomycetemcomitans colonization outside the gums is influenced by deep periodontal pockets and diagnosis. Buccal mucosa levels reflect subgingival bacterial load in periodontitis patients.
Area of Science:
- Oral microbiology
- Periodontology
- Bacterial pathogenesis
Background:
- Actinobacillus actinomycetemcomitans is linked to periodontitis.
- Understanding its extracerevicular oral colonization is crucial for disease management.
Purpose of the Study:
- To identify factors affecting Actinobacillus actinomycetemcomitans colonization in the oral cavity beyond the gums.
- To correlate subgingival bacterial load with extracerevicular sites.
Main Methods:
- Quantified cultivable Actinobacillus actinomycetemcomitans in subgingival plaque, saliva, and buccal/tongue mucosa samples from 33 periodontitis patients.
- Compared bacterial levels between localized juvenile periodontitis (LJP) and non-LJP patients.
- Utilized multiple regression analysis to assess influencing factors on buccal mucosa colonization.
Main Results:
- Significantly higher Actinobacillus actinomycetemcomitans levels were found in subgingival plaque of LJP patients compared to non-LJP patients.
- Actinobacillus actinomycetemcomitans infected buccal mucosa (85%) and saliva (77%) frequently.
- Deep periodontal pockets and diagnosis significantly influenced buccal mucosa bacterial counts.
Conclusions:
- Buccal mucosa colonization by Actinobacillus actinomycetemcomitans appears to mirror the subgingival bacterial burden.
- Periodontal status and specific diagnoses are key determinants of extracerevicular oral colonization.
