a)

Gastro-oesophageal reflux disease

b)

Bulimia / Anorexia

c)

Alcoholism

d)

Arthritis

2. 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

3. Which of the following statements is not true regarding the Basic Erosive Wear Examination (BEWE) index?

a)

BEWE is a new scoring system for erosion development for the general practitioner

b)

BEWE gives guidance towards clinical management of erosion

c)

BEWE classifies clinical erosion defects and allows allocation in risk levels

d)

BEWE is a scoring system developed for epidemiological studies

4. 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

5. Which of the following statements is correct in respect to caries and erosion?

a)

Caries and erosive defects will never be seen together in one patient

b)

Both result in hard tissue defects which are first treated with minimally-invasive fillings in first instance

c)

For both diseases, there does not exist any primary prevention techniques

d)

For both diseases, flouride containing rinses may constitute part of the therapy

6. 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

7. 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

8. 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

9. According to the BEWE scoring system, which of the following numbers represents the most severe level of erosion?

a)

1

b)

3

c)

5

d)

10

10. 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
