1. Which of the following statements is true for the Erosion Diagnostic Set?

a)

It offers clear assessment of erosive lesions, systematic assessment of risk factors, treatment and monitoring

b)

It is an alternative documentation system for all recall patients

c)

It is based on opinions of dentists and dental hygienists regarding erosion treatment

d)

This set offers office-specific adaptation possibilities for measuring salivary flow rate

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. 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

4. 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

5. 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

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

a)

Attrition

b)

Caries

c)

Erosion

d)

Abrasion

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

a)

20%

b)

30%

c)

50%

d)

70%

8. 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

9. 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

10. 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
