Periodontal Disease Pathogenesis Quiz

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.
