Question 1

What type of fluoridation uses milk as a vehicle for fluoride delivery?&#10;A)Milk fluoridation&#10;B)Yogurt fluoridation&#10;C)Cheese fluoridation&#10;D)Salt fluoridation

Accepted Answer

A)Milk fluoridation is the addition of 5 mg of fluoride to 1 liter of milk.

Question 2

What are optimal fluoride concentrations levels based on?&#10;A)Water temperatures&#10;B)Humidity&#10;C)Air temperatures&#10;D)Water consumption

Accepted Answer

C)The U.S.Public Health Service established non-regulatory standards for optimal concentrations of fluoride in the drinking water.These standards are based on the annual average of maximum daily air temperatures.

Question 3

What is salt fluoridation?&#10;A)It is the addition of salt and fluoride to water.&#10;B)These components are added to preserved food.&#10;C)These components are added to table salt.&#10;D)Patients get daily fluoride intake through salt blocks.

Accepted Answer

C)Many countries without centralized water distribution systems have chosen to add fluoride to table salt,a process known as salt fluoridation.

Question 4

What compound was the FIRST used in controlled water fluoridation programs and is still used in smaller communities?&#10;A)Stannous fluoride&#10;B)Neutral fluoride&#10;C)Sodium silicofluroide&#10;D)Sodium fluoride

Accepted Answer

D)Sodium fluoride was the first compound used in controlled water fluoridation programs and it is still used in many water systems in smaller communities.

Question 5

What occurs when an excess amount of fluoride is added to the drinking water over several days,usually secondary to an overfeed from malfunctioning equipment or maintenance errors?&#10;A)Hypofluoridation&#10;B)Hyperfluoridation&#10;C)Excessive fluorosis&#10;D)Community fluoridation

Accepted Answer

B)Hyperfluoridation occurs when an excess amount of fluoride is added to the drinking water over several days,usually secondary to an overfeed from malfunctioning equipment or maintenance errors.

Question 6

Water fluoridation is a controversial subject.In regard to fluoride,the media is usually more interested in controversy than risk.&#10;A)Both statements are true.&#10;B)Both statements are false.&#10;C)First statement is true,second statement is false.&#10;D)First statement is false,second statement is true.

Accepted Answer

A)Both statements are true.Fluoride is a very controversial subject and the media focuses on the negative rather than the positive effects.

Question 7

How do water fluoridation systems prevent excess water fluoridation?&#10;A)A limited amount of fluoride is maintained in day tanks.&#10;B)Proper controls are used to feed fluoride from the hoppers to distilling tanks.&#10;C)Metering pumps&#10;D)All of the above

Accepted Answer

D)All of the answers are correct.The CDC maintains a national program for proficiency testing,which compares the water plants' results to reference standards with known fluoride concentrations.

Question 8

What is the optimal level of fluoride in water?&#10;A)0)1-0.6 ppm&#10;B)0)7-1.2 ppm&#10;C)1)5-2.0 ppm&#10;D)2)5-3.2 ppm

Accepted Answer

B)The optimal fluoride concentration of one's primary water source should be 0.7-1.2 ppm.

Question 9

What is the MOST frequently used compound for water fluoridation in the United States today?&#10;A)Hydrofluosilicic acid&#10;B)Sodium silicofluoride&#10;C)Sodium fluoride&#10;D)Stannous fluoride

Accepted Answer

A)Today,the most frequently used compound for water fluoridation in the United States is hydrofluosilicic acid because of its low cost and ease of handling.

Question 10

Why is the fluoridation cost per person lower in larger communities and higher in smaller communities?&#10;A)Inverse relationship&#10;B)Reverse relationship&#10;C)Direct relationship&#10;D)Indirect relationship

Accepted Answer

A)An inverse relationship exists between the cost per person and the size of the population of a community.
