What type of bacteria is present in periodontitis?

Many: "red complex" bacteria consisting of porphyromonas gingivalis, treponema denticola, and tannerella forsythia are strongly associated with periodontal infection. The change from periodontal health to disease is associated with the displacement of a predominantly gram-positive bacterial flora in the periodontal sulcus by gram-negative anaerobes.

Bacteria: Healthy and disease-causing bacteria can generally be grouped into two categories: the harmless or helpful bacteria are usually known as gram positive aerobic bacteria. In periodontal disease, the bacterial balance shifts over to gram negative. Most implicated bacteria include: actinobacillus actinomycetemcomitans, porphyromonas gingivalis, bacteroides forsythus, treponema denticola, t. Socransk.
