1. 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

2. What might be a clinical presentation of erosion?

a)

Erosion can lead to wedge-shaped defects with depth clearly exceeding width and sharp edges

b)

Erosion shows flat glossy areas with distinct margins and corresponding defects on antagonistic teeth

c)

Erosion can lead to defects with depth clearly exceeding width and sharp edges

d)

Erosion shows rounded edges and often shows a rim of intact enamel along the gingival margin of facial surfaces due to the protection by sulfus fluid and / or plaque

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

a)

Attrition

b)

Caries

c)

Erosion

d)

Abrasion

4. 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

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. According to the BEWE system, what does a 2 represent in the scoring of erosive lesions?

a)

Distinct defect, dental hard tissue loss of more than 50% of the surface area

b)

No surface loss

c)

Distinct defect, dental hard tissue loss of less than 50% of the surface area

d)

Initial loss of surface texture

7. Erosion can be caused or aggravated by various extrinsic factors. Which of the following do not apply?

a)

Certain medicines / drug abuse

b)

Strenuous exercise

c)

Lactovegetarian diet

d)

Oral hygiene products with fluoride content

8. 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

9. What is dental erosion?

a)

Dissolution of dental hard tissue by intrinsic or extrinsic acidic environment without the involvement of bacteria

b)

Loss of dental hard tissue due to mechanical interaction of teeth and other materials, such as a toothbrush and toothpaste

c)

Abnormal occlusal loading, predisposing cervical enamel to mechanical and chemical wear

d)

Dissolution of hard tissue by bacterial acids

10. 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
