Microbial Insights: The Gingival Health Quiz
Microbial Insights: The Gingival Health Quiz
Test your knowledge of the microbial factors associated with gingival health and periodontal disease. This quiz explores complex theories about microbial biofilms and their role in oral health.
Key Topics:
- Microbial Complexes
- Red Complex Pathogens
- Biofilm Evolution
- Gram-Positive and Gram-Negative Bacteria
Microbes designated as __,__, __, and __ were thought to be compatible with gingival health
Red, Orange, Yellow, Green
Yellow, green, orange, blue
Yellow, green, blue, purple
Red complexes can be found in the absence of periodontal disease.
True
False
We now recognize...
Pathogenic microbial biofilm is a prerequisite for perio to develop, but the presence of a pathogenic oral biofilm alone is insufficient to cause the disease
A pathogen oral biofilm alone is enough to cause an inflammatory disease
While red complex are strongly associated with inflammatory disease, there is no evidence to support that they are potent initators of the disease
Red complex microorganisms are strongly associated with inflammatory disease and evidence shows they are potent initatiors of the disease
The ecological plaque hypothesis states thatit is a shift in the local environment that drives the changes in microbial composition
True
False
What theory is this: Host related factors and environment factors are all now recognized as major factors that contribute to the initiation and progression of periodontal disease
Ecological
Host-response
Keystone pathogen
What theory is this: The presence of certian microbial pathogens - even in low numbers - can cause a shift from beneficial to pathogenic microbes in the biofilm community
Ecological
Host Response
Keystone Pathogen
Biofilms can exist on any solid surface that is exposed to a microbe containing fluid
True
False
Select the time frame: Microbes produce an initial extracellular protective matric and become increasingly resistant to antiseptics and antibiotics
2 to 4 hours
6 to 12 hours
2 to 4 days
Select the time frame: The biofilm evolves into fully mature biofilm colonies that are extremely resistant to antibiotics; can rapidly recover from mechanical disruption and reform a mature biofilm with 24 hours
2 to 4 hours
6 to 12 hours
2 to 4 days
Select the time frame: Microbes form strongly attached microcolonies
2 to 4 hours
6 to 12 hours
2 to 4 days
Within minutes, free-floating microbes attach to a surface.
