Question 1

Which caries risk case requires an acid neutralizing rinse after snacks and meals for patients 6 years and older to adult?&#10;A) Low risk&#10;B) Moderate risk&#10;C) High risk&#10;D) Extreme risk

Accepted Answer

Only extreme risk requires acid neutralizing rinses after snacking and meals. Low risk, moderate risk, and high risk do not require acid neutralizing rinses.

Question 2

Two or more applications of fluoride varnish per year are effective in preventing caries in high-risk populations. Applying fluoride varnish every 6 months is effective in preventing caries in children and adolescents.

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

Both statements are true.

Accepted Answer

Both statements are True. Both of these are accurate clinical recommendations for fluoride varnish application. The other choices are incorrect.

Question 3

What is the recall interval for a patient age 6 years and older to adult who has moderate caries risk?&#10;A) 1 to 2 months&#10;B) 3 months&#10;C) 4 to 6 months&#10;D) 12 months

Accepted Answer

Recall intervals for caries risk examinations are shorter as caries risk increases. An interval of 4 to 6 months is recommended for recall examinations for moderate caries risk patients; 1 to 2 months and 3 months are too short for patients at moderate risk. The 6 to 12 month range is recommended for patients at low risk.

Question 4

The goal of caries management is to restore and maintain a balance between protective factors and pathologic factors because this balance leads to remineralization of early carious lesions and/or prevents future caries.

A) Both the statement and the reason are correct, and they are related.
B) Both the statement and the reason are correct, but they are not related.
C) The statement is correct, but the reason is not.
D) The statement is not correct, but the reason is correct.
E) Neither the statement nor the reason are correct.

Accepted Answer

The statement and reason for restoring a caries balance as the goal of caries management are both correct. The other choices are incorrect.

Question 5

Saliva is essential to controlling caries because saliva provides minerals and proteins that protect the teeth.&#10;A) Both the statement and the reason are correct, and they are related.&#10;B) Both the statement and the reason are correct, but they are not related.&#10;C) The statement is correct, but the reason is not.&#10;D) The statement is not correct, but the reason is correct.&#10;E) Neither the statement nor the reason is correct.

Accepted Answer

Both statements are correct and related. Adequate salivary flow is important to protect the teeth from dental caries. The other choices are incorrect.

Question 6

Placement of restorations reduces the bacterial challenge. Bacterial challenge can be reduced by antibacterial therapy.&#10;A) Both statements are true.&#10;B) Both statements are false.&#10;C) The first statement is true, and the second statement is false.&#10;D) The first statement is false, and the second statement is true.

Accepted Answer

Placement of restorations does not reduce the bacterial challenge. Bacterial challenge is reduced by antibacterial therapy such as chlorhexidine use. The other choices are incorrect.

Question 7

All of the following types of fluoride are included in dentifrices marketed in the United States except one. Which is the one exception?&#10;A) Sodium fluoride&#10;B) Sodium monofluorophosphate&#10;C) Stannous fluoride&#10;D) Silver diamine fluoride

Accepted Answer

Silver diamine fluoride is not included in toothpastes marketed in the United States. The other choices are all included in toothpastes marketed in the United States.

Question 8

Patients with frank carious lesions, radiographic approximal lesions, white spot lesions, or restorations in the past 3 years should have a saliva and a bacterial culture taken. All patients should have a salivary flow rate test for caries risk assessment.

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

Accepted Answer

Patients with any of these four disease indicators should have a bacterial culture taken. Only patients with dry mouth or visually detected low salivary flow should have a salivary flow rate test.

Question 9

Select the factors for high caries risk in a child 0 to 4 years old.&#10;A) Visibly adequate salivary flow&#10;B) Sleeps with bottle filled with something other than water&#10;C) Nurses ad lib&#10;D) Appliances present&#10;E) Any between meal snacks containing sugar or cooked starch&#10;F) Recent dental restorations (<2 years)

Accepted Answer

Sleeps with bottle filled with something other than water, nurses ad lib, appliances present, and recent dental restorations are factors for high caries risk in a child 0 to 4 years old. Visibly adequate salivary flow is a protective factor. Any between meal snacks containing sugar or cooked starch is incorrect as frequent snacking more than 3 times a day between meals is the risk factor.

Question 10

All of the following statements are true regarding xylitol except one. Which is the one exception?&#10;A) Xylitol enhances remineralization.&#10;B) Xylitol inhibits the transfer of bacteria from person to person.&#10;C) Xylitol inhibits future recolonization.&#10;D) Xylitol use is recommended twice daily.

Accepted Answer

Xylitol use is recommended four to five times daily, two tabs of gum or two lozenges each time. The other statements are all correct statements about xylitol.

Question 11

Which caries risk classification requires use of 1.1% sodium fluoride toothpaste rather than an over-the-counter (OTC), fluoride-containing toothpaste for patients age 6 years and older to adult?&#10;A) Low risk&#10;B) Moderate risk&#10;C) High risk&#10;D) Extreme risk

Accepted Answer

The answer of Which caries risk classification requires use of...

Question 12

For high-risk and extremely high-risk individuals, chlorhexidine is recommended because it can be more effective than fluoride when there is high bacterial challenge.&#10;A) Both the statement and the reason are correct, and they are related.&#10;B) Both the statement and the reason are correct, but they are not related.&#10;C) The statement is correct, but the reason is not.&#10;D) The statement is not correct, but the reason is correct.&#10;E) Neither the statement nor the reason is correct.
