Which bacterial test for which patient?

If you only wish to obtain an overview of the 5 most pathogenic bacteria, an analysis with the basic micro-IDent® test is sufficient. An analysis of 11 bacterial species with micro-IDent®plus can give you a precise picture of your patient’s individual bacterial load, however.

Whether to test for 5 or 11 bacterial species?

A marker bacteria analysis with micro-IDent®/micro-IDent®plus provides information on the occurrence and concentration of 5 and 11 bacterial species respectively and their affiliation with “bacterial complexes”. According to Sigmund Socransky’s complex theory, the composition of the subgingival flora reflects the course of the periodontitis. The organisms Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola and Prevotella intermedia in particular are considered to have very high or high pathogenic activity.

The basic test micro-IDent® allows the detection of 5 periodontopathogenic germs

  • Aggregatibacter actinomycetemcomitans (Aa)
  • Porphyromonas gingivalis (Pg)
  • Tannerella forsythia (Tf)
  • Treponema denticola (Td)
  • Prevotella intermedia (Pi)

The "big" test micro-IDent®plus enables the detection of a total of 11 marker germs

  • Aggregatibacter actinomycetemcomitans (Aa)
  • Porphyromonas gingivalis (Pg)
  • Tannerella forsythia (Tf)
  • Treponema denticola (Td)
  • Prevotella intermedia (Pi)
  • Parvimonas micra (Pm)
  • Fusobacterium nucleatum (Fn)
  • Campylobacter rectus (Cr)
  • Eubacterium nodatum (En)
  • Eikenella corrodens (Ec)
  • Capnocythophaga sp. (Cs)

Advantage of testing for 11 marker bacteria

Although the five bacterial species that can be detected with micro-IDent® are the marker bacteria with the highest pathogenicity, testing for a total of 11 species with micro-IDent®plus is advantageous. The additional marker bacteria covered are “early colonizers” or “bridge species”, which play an important role in the development of periodontal diseases.

In some cases, these bacterial species are key factors in determining the choice of therapy. With regard to the choice of the most appropriate antibiotic in particular, it is important to know which periodontopathogenic bacteria are driving the disease in the individual patient. Because it is only on the basis of detailed information that the therapy be adapted in an ideal way, thus enhancing the success of treatment.
