A leukocyte travels through the bloodstream to an infection site and pushes its way between the cells lining the blood vessel. This process of exiting the blood vessel is termed:

Pus at a site of inflammation consists of:

The complement system is part of:

A leukocyte secretes a biologically active compound that attracts more immune cells to an infection site. Biologically active compounds secreted by cells that activate the body's immune system are termed:

One human mouth is home to more microorganisms than there are people on the planet Earth. Periodontal disease is a bacterial infection. (t/f)

The type of bacteria that can cause periodontal disease are referred to as:

The cell-to-cell adherence of one oral bacterium to another is termed:

Socransky grouped microorganisms into complexes and assigned each a color. Which color signifies bacterial species that are dominant in the late stages of biofilm development?

What is periodontitis?

why is it is difficult to identify specific periodontal pathogens?

Periodontal pathogens can be passed from the oral cavity of one person to another by direct contact. Periodontal pathogens also can be spread by contact with inanimate objects, such as cell phones. (t/f)

Which of the following statements best describes bacterial blooms?

Research suggests that this type of bacterial subgingival attachment is the most detrimental to the periodontal tissues:

A biofilm is a living film that grows on a surface. Biofilms are only found in the mouth. (t/f)

Legionnaire's disease, which killed 29 people in 1976, was caused by:

When examining a bacterium under a microscope, you note the following features: a double cell membrane and a red stain. Which type of bacteria are you examining?

How do bacteria adhere during the process of coaggregation to a tooth surface?

Which of the following statements best describes bacterial blooms?

All of the following are true regarding the benefits of daily disruption of plaque biofilms, EXCEPT:

What is true regarding the benefits of daily disruption of plaque biofilms?

What is the term for a bacterial virulence factor that is a class of proteins found in living bacterial cell membranes?

Free-floating periodontal pathogens can cause periodontal disease. Biofilm development always begins supragingivally (t/f)

If a bacterium wants to join a biofilm, it should look for which of the following conditions:

A leukocyte exits the blood vessel and enters the connective tissue to travel to the site of an infection. What is the process called whereby leukocytes are attracted to an infection site?

Your friend is walking on the beach barefoot and cuts his foot on something sharp hidden in the sand. At home, he washes the foot and puts on an adhesive bandage over the cut. The next day the area around the cut is swollen, red, and hot. What is the cause of the REDNESS?

A leukocyte secretes a biologically active compound that attracts more immune cells to an infection site. Biologically active compounds secreted by cells that activate the body's immune system are termed:

In a bacterial infection of the periodontium, the cells that arrive to the infection site first (the rapid responders) are the:

The complement system is part of:

All of the following are symptoms of inflammation EXCEPT:

The intensity of the immune response is the same for every person. The local immune response is the same for each affected area. (t/f)

In which phase of periodontal disease progression does PGE2 mediate bone destruction by stimulating large numbers of osteoclasts to resorb alveolar bone?

Which of the following is a biochemical mediator that plays the most important role in the bone destruction seen in periodontitis?

In which phase of periodontal disease progression do the increasing numbers of PMNs rush to the site of the periodontal pathogens and in doing so destroy healthy gingival connective tissue and migrate through the junctional epithelium to form a "wall of cells" between the plaque biofilm and the sulcus wall

In which phase of periodontal disease progression does the coronal-most portion of the junctional epithelium first detach from the tooth surface?

Bleeding on probing is considered a clinical indication of active periodontitis (t/f)

The absence of BOP means that the particular site is unlikely to lose attachment (t/f)

What is an important parameter for assessing the failure of an implant?

What does radiographic assessment indicate?
