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.
Aggressive periodontitis was found in 5.9% of the subjects (4.3% localized and 1.6% generalized). This was significantly associated with current smoking and ethnic origin (North African). [citation needed] Eres 2009 examined 3,056 students between the ages of 13 and 19 years at public schools in Turkey.
Dental plaque, the precursor of periodontal disease, is a complex biofilm consisting mainly of bacteria, but also archaea, protozoa, fungi and viruses. Viruses that specifically infect bacteria—bacteriophages—are most common in the oral cavity. Viral roles in the progression of periodontal disease as of 2017 remains poorly explored. [1]
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).
The bone destruction patterns that occur as a result of periodontal disease generally take on characteristic forms. This X-ray film displays a horizontal defect . This X-ray film displays two lone-standing mandibular teeth, #21 and #22: the lower left first premolar and canine, exhibiting severe bone loss of 30-50%.
