Perio Quiz Chapters 11-13

A single microscopic organism is termed:

• Bacteria

• Bacterium

• Nucleoli

• Aerobic

Bacteria that have a double cell membranes and do not stain purple with crystal violet are called

A well-organized community of bacteria that adheres to surfaces and is embedded in an extracellular slime layer is termed:

• Aerobic

• Anaerobic

• Biofilm

• Bacterial microcolony

Which structure of a biofilm protects the bacterial micro-colonies from systemic antibiotics and the body's immune system:

• Acquired Pellicle

• Extracellular slime layer

• Fluid Channels

• Primitive communication system

Which of the following would be the most effective in controlling the bacteria in a dental plaque biofilm?

• Systemic antibiotic

• Antimicrobial agent

• Very high doses of antibiotics

• Toothbrush and floss

Why is frequent periodontal instrumentation important in the control of dental plaque biofilms located in perio pockets?

• A toothbrush and floss cannot clean root surfaces within a perio pocket

• Few patients take the time for self-care at home

Current perspective on the etiology of perio disease states that plaque biofilm is necessary for initial inflammation, and plaque biofilm alone is not sufficient for periodontal destruction

• The first phase is true, second phrase is false

• The first phrase is false, the second phrase is true

• Both phrases are true

• Both phrases are false

The primary purpose of the immune system is to:

• Defend the life of the host

• Identify bacterial invaders

• Cause swelling and redness at the infection site

• Phagocytize bacteria

All of the following are classic symptoms of acute inflammation. EXCEPT:

• Loss of function

• Bruising

• Swelling

• Heat

Which immune cells secrete antibodies?
