For example, when Porphyromonas gingivalis and Tannerella forsythia are present in the subgingival plaque, a patient is more likely to develop chronic periodontitis, more likely to progress to advanced periodontal disease, and less likely to experience a successful treatment outcome.
The microbiological parameters Aggregatibacter actinomycetemcomitans (Aa), Fusobacterium nucleatum (Fn), Porphyromonas gingivalis (Pg) and Prevotella intermedia (Pi) were recorded.
Microbiological studies have demonstrated Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Fusobacterium nucleatum, and Treponema denticola organisms, suggesting that many pathogens may be involved in the disease process.

This leaves us vulnerable to infections by bacteria that cause gum disease, such as Porphyromonas gingivalis.
Using culturing-based studies of the bacteria growing at healthy and periodontitis-affected sites, three species have been identified as significantly associated with clinical disease severity: Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia.
