1. 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.

2. 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

3. 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

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

a)

Certain medicines / drug abuse

b)

Strenuous exercise

c)

Lactovegetarian diet

d)

Oral hygiene products with fluoride content

6. 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

7. 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

8. What is the most common extrinsic cause of dental erosion?

a)

Frequent consumption of acidic food and drinks

b)

Inadequate dental hygiene habits

c)

Gastro-oesophageal reflux disease (GORD)

d)

Illegal drugs, such as ecstasy

9. 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.

10. 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
