Study Notes

Host Immune Response in Periodontitis

The main effect of host immune-inflammatory response in the pathogenesis of periodontitis is tissue destruction and bone loss.

Virulence Factors of Periodontal Pathogens

One virulence factor of periodontal pathogens related to bacterial colonization is the ability to adhere to and colonize the tooth surface.
A key microbial virulence factor that represents direct damage of the periodontium is lipopolysaccharide (LPS).

Bacterial Colonization

The pellicle plays a crucial role in bacterial colonization to the tooth surface by providing a receptor for bacterial adhesion.
A. viscosus adheres to a polysaccharide receptor on cells of Streptococcus sanguis through surface fimbriae, facilitating bacterial colonization.
