Water Fluoridation - still the answer quiz

This is a 6-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 range of recommended optimal fluoride concentrations in public water supplies in Australia is:

(a).  0.5 – 1.0 ppm
(b).  0.6 – 1.1 ppm
(c).  0.6 – 1.0 ppm
(d).  0.8 – 1.0 ppm

Question 2. Fluoride acts to prevent dental caries through:

(a).  Post-eruptive mechanism only
(b).  Pre-eruptive mechanism only
(c).  Both pre- and post-eruptive mechanisms

Question 3. Increased use of non-public water supplies has resulted in:

(a).  An increase in caries equally in both deciduous and permanent teeth
(b).  An increase in caries in the permanent dentition primarily
(c).  No change in caries rates as the disease is multifactorial
(d).  An increase in caries rates in the deciduous dentition primarily

Question 4. Now that there are many other fluoride vehicles ( especially widespread use of toothpaste with fluoride), water fluoridation results in a reduction in dental caries of:

(a).  50–60%
(b).  10–20%
(c).  30–50%
(d).  20–40%

Question 5. The recommendation for fluoride intake for children living in non-fluoridated areas is:

(a).  Make up one litre of fluoridated water using 1mg fluoride tablet or drops and use this water for drinking and cooking
(b).  Just use toothpaste with fluoride as recommended for your age group
(c.)  Take a 1mg fluoride tablet daily
(d).  It is not a problem

Question 6. The mechanisms through which fluoride acts to prevent caries do not include:

(a).  inhibiting demineralisation by raising the critical pH for dissolution of tooth enamel
(b).  enhancing remineralisation by lowering the energy needed for reformation of apatite crystals or calcium fluoride
(c).  inhibiting acid formation by micro-organisms involved in caries formation
(d).  fluoride from the dental plaque is taken up by demineralised enamel to form a more stable enamel structure
