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

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. 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

3. 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

4. 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)

5. Which of the following statements is not true regarding the Basic Erosive Wear Examination (BEWE) index?

a)

BEWE is a new scoring system for erosion development for the general practitioner

b)

BEWE gives guidance towards clinical management of erosion

c)

BEWE classifies clinical erosion defects and allows allocation in risk levels

d)

BEWE is a scoring system developed for epidemiological studies

6. Which of the following is not a proactive method in the assessment of erosion?

a)

Observing the patient’s dietary intake for several consecutive days

b)

Identifying intrinsic risk factors

c)

Reviewing the patient’s tooth brushing habits

d)

Ignoring the patient’s general health

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 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

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 following statements best describes the type of tooth wear, which might occur when a patient consistently brushes their teeth immediately before exposure to erosive agents?

a)

A reduction of the pellicle which reduces the protection against erosion from acidic foods and drinks

b)

Enamel wear due to attrition alone

c)

Abrasion due to softening of the enamel

d)

Increased vulnerability to erosion due to the softening of the dentine
