1. 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

2. What is dental erosion?

a)

Dissolution of dental hard tissue by intrinsic or extrinsic acidic environment without the involvement of bacteria

b)

Loss of dental hard tissue due to mechanical interaction of teeth and other materials, such as a toothbrush and toothpaste

c)

Abnormal occlusal loading, predisposing cervical enamel to mechanical and chemical wear

d)

Dissolution of hard tissue by bacterial acids

3. 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

4. Which of the following common foods and drinks may have an erosive effect?

a)

Milk

b)

Bread

c)

Honey

d)

Sports drinks

5. Erosion can be caused or aggravated by various extrinsic factors. Which of the following do not apply?

a)

Certain medicines / drug abuse

Strenuous exercise

c)

Lactovegetarian diet

d)

6. Which of the following statements does not describe the benefits of BEWE?

a)

Gives guidance toward clinical management

Helps to monitor the process as the amalgam-fillings “elevate” above the tooth

Classifies clinical visible defects

d)

Matches clinical signs to risk levels

7. Which of the following may never be the first visible signs of erosion?

a)

Localised silky and shiny tooth surface

b)

Optical radioopacity

c)

Rim of intact enamel on facial surfaces along gingival margin

d)

Loss of perikymata

8. 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

9. 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

10. 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
