Study Notes
Virulent Factors in Periodontitis
- Pathogens in periodontitis express various virulent factors, which increase their ability to cause disease.
- These factors may include fimbriae and toxins that enhance bacterial adherence and tissue invasion.
Host Immune-Inflammatory Response
- The host's immune response in periodontitis leads to inflammation, resulting in tissue destruction and loss of dental support structures.
- Prolonged inflammation can exacerbate periodontal tissue damage, contributing to disease progression.
Bacterial Strains and Adherence
- Streptococcus gordonii is an example of a bacterial strain that adheres to a polysaccharide receptor on cells of another strain, enhancing co-aggregation among bacteria in the oral cavity.
Coaggregation in Pathogenesis
- Coaggregation allows different bacterial species to adhere to one another, forming complex biofilms in periodontal pockets.
- This process facilitates the development of pathogenic communities that can resist host defenses and conventional treatment methods.
Importance of Adhesin Receptors
- Adhesin receptors on bacterial surfaces mediate the initial attachment to host tissues, which is crucial for colonization and infection.
- These receptors enhance the ability of bacteria to persist in the periodontal environment and contribute to the disease's chronic nature.
