Specific
bacteria as risk factors in periodontal disease
Several
bacterial species are known to be periodontopathogen. They have different
virulence factors and are more prevalent in cases than in healthy subjects.
Their detection could be used to planify more specific antimicrobial periodontal disease therapies
and also prevent a worst clinical prognosis.
These bacteria are Porphyromonas gingivalis, Bacteroides forsythus, Treponema
denticola and Actinobacillus actinomycetemcomitans.
- P. gingivalis is associated with chronic periodontitis and, sometimes,
advanced periodontal disease. It also has been detected in atheromatous plaques
in subjects with cardiovascular diseases.
- B.
forsythus is also associated with chronic periodontitis, and it
is very prevalent.
- Treponema
denticola is a spirochete involved in periodontal disease.
- A.
actinomycetemcomitans is associated with periodontitis in children
and adolescents, and with aggressive pictures.
