Which bacteria is key in aggressive periodontitis?

  1. P. gingivalis

  2. T. denticola

  3. A.A

  4. Fusobacterium nucleatum

The correct answer is: A.A

Aggressive periodontitis is a type of gum disease that can cause rapid and severe damage to the gums and surrounding tissues. It is often caused by excessive growth of certain bacteria in the mouth. While P. gingivalis and T. denticola have been found to contribute to periodontitis, the key bacteria in aggressive periodontitis is actually A. A. This bacteria is known for its aggressive nature and ability to cause significant damage to the gums. Fusobacterium nucleatum may also contribute to periodontitis, but it is not considered the primary bacteria in aggressive cases.
