Aggressive periodontitis is often characterised by a rapid loss of periodontal attachment associated with highly pathogenic bacteria and an impaired immune response. Various studies have associated Aggregatibacter actinomycetemcomitans , formerly known as Actinobacillus actinomycetemcomitans , with aggressive periodontitis.
Aggregatibacter actinomycetemcomitans is a Gram-negative, facultative anaerobe, nonmotile bacterium that is often found in association with localized aggressive periodontitis, a severe infection of the periodontium. It is also suspected to be involved in chronic periodontitis. [1]
Aggressive periodontitis is distinguished from the chronic form mainly by the faster rate of progression. Loss of attachment may progress despite good oral hygiene and in the absence of risk factors such as smoking. Aggressive periodontitis may occur in younger persons and there may a genetic aspect, with the trait sometimes running in families ...
[1] [2] At least 16 systemic diseases have been linked to periodontitis. These systemic diseases are associated with periodontal disease because they generally contribute to either a decreased host resistance to infections or dysfunction in the connective tissue of the gums , increasing patient susceptibility to inflammation-induced destruction.

At the time the system was designed, the initiation of periodontal disease was thought to develop from a continuum from an inflammation-free state to gingivitis, to calculus deposition and pocket formation and then to progressive disease. Treatment concepts were based on the concept of pocket depths being the most critical criterion for ...
Bone loss from aggressive periodontitis that led to an exposed furcation on an upper molar. In health, the bone exists about a millimeter and a half away from the cementoenamel junction, which is the line that separates the crown from the root trunk (the line can be seen clearly in the photo).
Entamoeba gingivalis from aggressive periodontal disease patient biofilm using phase contrast microscope 1000x. It is recognizable through its dense core in the middle, formed by a central point encircled by a circular halo and surrounded by bigger phagosomes inside a greyish cytoplasm.
