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.
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 ...
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.
[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.
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]
Periodontal pathogens are bacteria that have been shown to significantly contribute to periodontitis. 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 ...
1: Total loss of attachment (clinical attachment loss, CAL) is the sum of 2: Gingival recession, and 3: Probing depth. Gingival recession, also known as gum recession and receding gums, is the exposure in the roots of the teeth caused by a loss of gum tissue and/or retraction of the gingival margin from the crown of the teeth. [1]
Generalized bone loss occurs most frequently as horizontal bone loss. [2] Horizontal bone loss manifests as a somewhat even degree of bone resorption so that the height of the bone in relation to the teeth has been uniformly decreased, as indicated in the radiograph to the rig defects occur adjacent to a tooth and usually in the form of a triangular area of missing bone, known as triangulation.
