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.
