The two strains of bacteria found to assist with periodontal health are Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans. Both are Gram-negative, anaerobic species of bacteria that are commonly found in the oral cavity, particularly in the subgingival biofilm.
Porphyromonas gingivalis is the most abundant and important bacteria found in periodontal diseases. It is a periodontal pathogen that produces a variety of enzymes, toxins, and other molecules that can cause tissue destruction and inflammation. Furthermore, P. gingivalis is associated with the development of periodontal diseases, including gingivitis and periodontitis.
Aggregatibacter actinomycetemcomitans is another Gram-negative, anaerobic bacterium that is commonly found in the oral cavity and has been linked to the development of periodontal diseases. It is known to produce a number of cell-surface components, including lipopolysaccharides and outer membrane proteins, which are thought to be involved in its virulence. Additionally, A. actinomycetemcomitans has been shown to produce enzymes that can degrade collagen, leading to tissue destruction and inflammation.
Both P. gingivalis and A. actinomycetemcomitans have been found to play an important role in the development of periodontal diseases. They are associated with the production of enzymes and toxins that can cause tissue destruction and inflammation, resulting in the destruction of periodontal tissues. Furthermore, their presence in the subgingival biofilm has been linked to the development of periodontal diseases. Therefore, it is important to reduce the levels of these two bacteria in order to maintain periodontal health.
