In periodontitis, which pathogen is known for its severity?

• A. Streptococcus mutans
• B. Aggregatibacter actinomycetemcomitans
• C. Streptococcus sobrinus
• D. Actinomyces israelii

Answer: (B)

The pathogen known for its severity in periodontitis is Aggregatibacter actinomycetemcomitans. This bacterium is particularly associated with aggressive forms of periodontitis, which can lead to rapid tissue destruction and tooth loss. It is recognized for its ability to evade the host's immune response and contribute to inflammatory processes that exacerbate periodontal disease. Aggregatibacter actinomycetemcomitans releases various virulence factors that enhance its pathogenic potential. These include toxins that can damage periodontal tissues and promote bone loss, making it a major contributor to periodontal disease severity. Its presence in subgingival plaque indicates a higher risk for the development of advanced periodontitis, distinguishing it from other pathogens which may be present but do not have the same association with aggressive disease progression. Other pathogens listed may play a role in periodontal disease, but they are not as strongly linked to severe periodontitis as Aggregatibacter actinomycetemcomitans, which is key to understanding the complexity of periodontal pathogens and their impact on oral health.
