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. 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 an initial sign of erosive tooth wear?

a)

Initial loss of surface texture (perikymata)

b)

Localised silky and shiny tooth surfaces

c)

Exposure of deeper parts of dentine

d)

Sometimes dull surfaces

4. What is the difference between primary prophylaxis and secondary prophylaxis of erosion?

a)

Secondary prophylactic measures are implemented when primary measures fail

b)

Primary prophylaxis addresses the risk factors for erosion before erosive lesions are present; secondary prophylaxis prevents the progression of existing lesions

c)

Primary prophylaxis prevents the progression of existing erosive lesions; secondary prophylaxis prevents the development of new lesions

d)

Primary prophylaxis measures should only be considered when working in a preventive orientated dental office; secondary prophylaxis measures in all cases are restorative treatments

5. 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

6. 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.

7. 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

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. Which of the following is not a proactive method in the assessment of erosion?

a)

Observing the patient’s dietary intake for several consecutive days

b)

Identifying intrinsic risk factors

c)

Reviewing the patient’s tooth brushing habits

d)

Ignoring the patient’s general health

10. 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
