1. 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

2. Which factor may cause erosion?

a)

Teeth grinding

b)

Sparkling mineral water

c)

Gastric fluids

d)

Milk

3. 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

4. Which of the categories below does not describe tooth wear?

a)

Attrition

b)

Caries

c)

Erosion

d)

Abrasion

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

a)

Gives guidance toward clinical management

b)

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

c)

Classifies clinical visible defects

d)

Matches clinical signs to risk levels

6. 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

7. 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

8. 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.

9. 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

10. 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
