1. What is the estimated prevalence of signs of erosion in the Western population?

a)

20%

b)

30%

c)

50%

d)

70%

2. 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

3. 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.

4. 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

5. 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

6. 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

7. Which of the following statements differentiates erosion from caries?

a)

Erosion is caused by extrinsic and intrinsic acids of bacterial origin; caries are caused by acids of non-bacterial origin

b)

The clinical presentation of erosion comprises localised silky shiny surface and rounded defects; caries present as white spots, with tooth surface intact initially, but later developing into rough defects

c)

Caries can be remineralised effectively with fluoride until there is no cavitation; erosive lesions can be remineralised effectively with fluoride at any stage of erosion development

d)

There is no need to differentiate caries from erosive defect because restorative treatment is needed in both cases

8. 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.

9. 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

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

a)

Attrition

b)

Caries

c)

Erosion

d)

Abrasion
