Dental erosion quiz

This is a 9-question quiz to test your knowledge of the materials provided in the Practice Information Sheet. Please record your choices on a piece of paper and use it to compare with the answers we provide at the bottom of this page.

Question 1      The pH is a direct indicator of the erosive potential of a particular  product. (Choose one answer.)

(a)  yes, the higher the pH the greater the erosive potential
(b)  yes, the lower the pH the greater the erosive potential
(c)  yes, the stronger the acid the greater the erosive potential
(d)  no, other chemicals accompanying the acid may modify the erosive potential

Question 2      Which statement is FALSE?
          Management of dental erosion involves:

(a)  accurate diagnosis of the condition and its causes
(b)  making the patient aware of the condition is not important as the patient  
      cannot control any of the endogenous factors anyway
(c)  physical protection of affected teeth
(d)  where possible, work with the patient’s doctor on exogenous factors

Question 3      Which statement is FALSE?
           Early signs of dental erosion in enamel include:

 (a)  rounding of sharp edges/angles
 (b)  dentine cupping or scooping
 (c)  thinning of enamel
 (d)  restorations present may appear to be above the tooth surface
 (e)  staining of enamel

Question 4      The extrinsic sources of acids in the oral environment can include: 
           (ONE of the following statements is false; pick the FALSE statement)

(a)  dietary eg acidic food
(b)  pharmacological eg acidic medication
(c)  gastric reflux
(d)  acid vapours (eg battery workshops)

Question 5      Pick the CORRECT statement:

(a)  the colour of an area with dental erosion is usually whiter than the natural
      tooth
(b)  the colour of an area with dental erosion is usually similar to tooth colour, may
      later become yellowish as enamel becomes thinner
(c)  the colour of erosion and carious lesion is the same
(d)  an area with dental erosion appears dull and chalky and later may become
     yellowish or stained

Question 6      Demineralised collagen in exposed root surfaces: (Choose one answer.)

(a)  is damaged beyond repair and has to be removed before placing a restoration

(b)  can be remineralised and regain almost its original profile and hardness even it has been physically damaged or left dehydrated

(c)  can be remineralised with fluoride and regain almost its original profile and hardness providing that it has been well hydrated by saliva and it has not been physically damaged

(d)  fluoride does not have any effect on demineralised collagen

Question 7      Brushing plays an important role in dental erosion. Pick the CORRECT statement.

(a)  apply toothpaste with fluoride and brush well immediately after acidic challenge

(b)  toothpaste can be very abrasive therefore do not apply toothpaste, but brush well immediately after acidic challenge

(c)  avoid toothbrushing for at least an hour after the acidic challenge

(d)  after the acid challenge rinse mouth immediately with water, milk or fluoride rinse, but do not brush for at least 30 minutes.

Question 8      The pH of gastric acid is:  (Choose one answer.)

(a)  around 1.2
(b)  5 - 7
(c)  2.5 - 4
(d)  above 7

Question 9      Maturity of enamel has been shown to reduce susceptibility to:
                    (Choose one answer.)

(a)  dental caries
(b)  dental erosion
(c)  both dental caries and dental erosion
(d)  none of the response options
