1. Which of the following statements is correct in respect to caries and erosion?

a)

Caries and erosive defects will never be seen together in one patient

b)

Both result in hard tissue defects which are first treated with minimally-invasive fillings in first instance

c)

For both diseases, there does not exist any primary prevention techniques

d)

For both diseases, flouride containing rinses may constitute part of the therapy

2. What might be a clinical presentation of erosion?

a)

Erosion can lead to wedge-shaped defects with depth clearly exceeding width and sharp edges

b)

Erosion shows flat glossy areas with distinct margins and corresponding defects on antagonistic teeth

c)

Erosion can lead to defects with depth clearly exceeding width and sharp edges

d)

Erosion shows rounded edges and often shows a rim of intact enamel along the gingival margin of facial surfaces due to the protection by sulfus fluid and / or plaque

3. 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

4. How does elmex^® EROSION PROTECTION dental rinse potentially protect teeth from erosive dental hard tissue loss?

a)

It leads to the formation of an amorphous precipitate rich in stannous ions on the tooth surface

b)

It encourages the integration of insoluble stannous-compounds into the outermost tooth layers

c)

It makes enamel and dentine more resistant to erosive acid attacks

d)

All of the above

5. 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

6. Which factor may cause erosion?

a)

Teeth grinding

b)

Sparkling mineral water

c)

Gastric fluids

d)

Milk

7. 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)

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

a)

Saliva

b)

Blood

c)

Enamel

d)

Dentine

9. 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

10. Which of the following statements is not true regarding the BEWE diagnostic system?

a)

It is a tool which helps to guide the practitioner in erosion management

b)

It’s a simple scoring system that evaluates the severity of erosion

c)

It was created because of a lack of harmonisation in the erosion diagnosis methods

d)

The scores of all the teeth are recorded
