1. 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

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 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. Which of the following factors need not be considered when diagnosing erosion?

a)

General health

b)

Salivary flow rate

c)

The clinical appearance of teeth

d)

Patient gender

5. Which of the following statements is not true, regarding the acid-resistant coat obtained with dental products containing stannous ions?

a)

Only the stannous ions incorporated in the outermost layers of the enamel show proven efficacy against erosion

b)

The stannous forms a depot on the tooth surface which already has protective properties against erosion

c)

Stannous ions form an insoluble reservoir on the tooth surface

d)

Stannous ions will be integrated in the outermost layer of the affected tooth at a later stage

6. Which of the following is not a primary prevention technique of dental erosion?

a)

Education about aetiology and erosion mechanisms

b)

Assessment of dietary intake and behavioural factors

c)

Promotion of adequate oral hygiene habits

d)

Strengthen eroded teeth with an erosion protection dental rinse just after acidic challenges

7. 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

8. Which factor may cause erosion?

a)

Teeth grinding

b)

Sparkling mineral water

c)

Gastric fluids

d)

Milk

9. 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

10. 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
