1. elmex^® EROSION PROTECTION toothpaste has been specifically formulated to help protect teeth against erosive acid attacks, against toothbrushing-related loss of softened enamel and against caries. It works in multiple ways. Which of the below statements is not true:

a)

The ChitoActive technology™ leads to the formation of a protective layer on the tooth surface.

b)

Chitosan is incorporated into the softened enamel, making it more resistant against further erosive acid attacks and against loss of softened enamel caused by toothbrushing.

c)

Stannous compounds from the protective layer are incorporated into the softened enamel, making it more resistant against further erosive acid attacks and against loss of softened enamel caused by toothbrushing.

d)

Amine fluoride protects against caries.

2. Which of the following is not one of the main biological factors related to erosion?

a)

Saliva

b)

Blood

c)

Enamel

d)

Dentine

3. Which of the following statements is not true regarding the influence of saliva on erosion?

a)

Saliva neutralises acid and prevents acidification by providing tooth minerals

b)

Increasing a low salivary flow rate can under no means stop the aggravation of erosion

c)

The efficacy against erosion is determined mainly by its composition and flow rate

d)

Saliva is the source of the dental pellicle, which has protective properties

4. Which of the following is not a primary prevention technique of dental erosion?

a)

Education about aetiology and erosion mechanisms

b)

Assessment of dietary intake and behavioural factors

c)

Promotion of adequate oral hygiene habits

d)

Strengthen eroded teeth with an erosion protection dental rinse just after acidic challenges

5. Certain oral hygiene procedures can increase the symptoms of erosion. Why?

a)

They are highly abrasive and are used incorrectly (e.g. using too much pressure when brushing teeth)

b)

They have a low pH but have active ingredients such as polyvalent cations or fluorides

c)

They have a high pH and additionally can buffer a drop in pH

d)

They are gentle on the teeth

6. Which of the following factors need not be considered when diagnosing erosion?

a)

General health

b)

Salivary flow rate

c)

The clinical appearance of teeth

d)

Patient gender

7. Why is erosion difficult to detect in its early stages?

a)

Erosion is rare

b)

Clinical signs are subtle

c)

Patients begin to experience pain as erosive lesions develop

d)

Patients experience pain before the dentine is exposed

8. Which of these patients will probably not be at risk for dental erosion?

a)

a pregnant woman

b)

an obese man

c)

a poly-medicated cancer patient

d)

a well-monitored patient in your office

9. According to the BEWE system, what does a 2 represent in the scoring of erosive lesions?

a)

Distinct defect, dental hard tissue loss of more than 50% of the surface area

b)

No surface loss

c)

Distinct defect, dental hard tissue loss of less than 50% of the surface area

d)

Initial loss of surface texture

10. Which of the following is not a primary prevention technique?

a)

Brush teeth with an especially abrasive toothpaste

b)

Restrict acidic drinks to consumption with meals

c)

Rinse mouth with water or with an erosion protection dental rinse

d)

Use soft tooth brushes
