E) Neither the statement nor the reason is correct.

Answer 1

Both the statement and the reason are correct, and they are related.

The most commonly used disclosing ingredient is:

A) methylene blue.
B) erythrosine dye.
C) formaldehyde.
D) fluorescein dye.

Answer 3

erythrosine dye.

Question 4

Oral biofilm in a healthy mouth is located mainly supragingivally but grows subgingivally in plaque-induced gingival disease. In the presence of mature bacterial plaque, the host immune response is activated.

A) Resistant to essential oils
B) Bacteria in biofilm relocate to state a new community
C) Transparent, mineralized mass of bacterial colonies
D) Composed of loosely attached and unattached, free-flowing bacteria

Question 8

Bacterial plaque as a biofilm is a risk factor for periodontal disease and oral malodor, whereas dental calculus does not cause oral disease.

A) Both parts of the statement are true.

D) before the client sees the oral findings.

Question 11

Dental plaque as a transparent film can be detected in several ways. Select all of the methods that can be used to detect dental plaque.

A) Use of a disclosant
B) Visibly evident thick deposits

B) Amount of calculus
C) Location of deposits
D) Presence of food debris

Question 14

A significant percentage of the population exhibits some type of periodontal disease. Effective oral hygiene assessment provides which of the following benefits? Select all that apply.

A) Communicates unmet needs to a client
B) Instructs a client in effective, individualized self-care
C) Protects a client from health risks
D) Determines a client's unmet needs

Question 15

Disease occurs when bacteria cause destruction that exceeds the reparative ability of the host. Furthermore, the quantity (amount) of the plaque is more important than the types (quality) of microorganisms present.

B) The first statement is false, and the second statement is true.
C) Both statements are true.
D) Both statements are false.

Question 16

A dental index converts specific clinical observations into a numeric value (score) to measure the level of oral hygiene of an individual or population. A high numeric value or index score indicates good oral hygiene.
