1. Which of the statements regarding the measurement of erosion progression is untrue?

a)

The assessment of the progression of erosive processes is largely standardised

b)

Study casts are difficult to quantify

c)

Computer generated 3D images are costly

d)

Metal markers are a simple way to measure erosion

2. 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

3. Is it advisable for people at risk of erosion to brush their teeth, and why?

a)

No, because the risk of losing even more dental hard tissue is too big (abrasion).

b)

No, this is not needed, as the acid kills the oral bacteria anyway.

c)

Yes, because otherwise caries may develop.

d)

Yes, because toothbrushing helps to remove the acidic compounds from the oral cavity.

4. Which of the following statements is not true regarding wedge-shaped defects?

a)

Wedge-shaped defects can be worsened by dental erosion

b)

Wedge-shaped defects should always be treated with adhesives; there is no need to assess aetiology

c)

Wedge-shaped defects may also be prone to caries

d)

Wedge-shaped defects have a multicausal aetiology

5. 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.

6. What is the difference between primary prophylaxis and secondary prophylaxis of erosion?

a)

Secondary prophylactic measures are implemented when primary measures fail

b)

Primary prophylaxis addresses the risk factors for erosion before erosive lesions are present; secondary prophylaxis prevents the progression of existing lesions

c)

Primary prophylaxis prevents the progression of existing erosive lesions; secondary prophylaxis prevents the development of new lesions

d)

Primary prophylaxis measures should only be considered when working in a preventive orientated dental office; secondary prophylaxis measures in all cases are restorative treatments

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

a)

Saliva

b)

Blood

c)

Enamel

d)

Dentine

8. What kind of toothbrush is recommended for people at risk of erosion or patients with erosion?

a)

a soft toothbrush

b)

a toothbrush of medium hardness

c)

a hard toothbrush

d)

No toothbrush, as you should not brush at all (too much abrasion)

9. Presence of erosive lesions often positively correlates with:

a)

Caries activity

b)

Fast drinking habit

c)

High buffering capacity of saliva

d)

Low salivary flow rate

10. According to the BEWE scoring system, which of the following numbers represents the most severe level of erosion?

a)

1

b)

3

c)

5

d)

10
