Q

Sodium fluoride (granulars or powders) and sodium fluorosilicate (granular only) are used in ____________ fluoride distribution systems.

These systems are used for _____ communities, <50,000 population.

A

Dry system (granulars/powders)- sodium fluoride and sodium fluorosilicate

Used for smaller communities, <50,000 population

37
Q

Fluorosilic acid is used is a ______ community distribution fluoridation method. It is used in______ communities of >50,000 population.

This is the most widely used fluoridation system in the United States.

A

Wet system (liquid)

Used for larger communities, >50,000 population

38
Q

Many credible sources have researched and found that there are no toxic residues in the water in which this fluoride compound has been added. The three research sources are the CDC, EPA, and AWWA.

What does AWWA stand for?

A

American Water Works Association

39

False

A

True

40
Q

What is the optimal level of fluoride in water?

A) 0.1–0.6 ppm

B) 0.7–1.2 ppm

C) 1.5–2.0 ppm

D) 2.5–3.2 ppm

A

B) 0.7–1.2 ppm

The optimal fluoride concentration of one’s primary water source should be 0.7–1.2 ppm.

41
Q

What are optimal fluoride concentrations levels based on?

A) Water temperatures

B) Humidity

C) Air temperatures

D) Water consumption

A

C) Air temperatures

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.

42
Q

What compound was the FIRST used in controlled water fluoridation programs and is still used in smaller communities?

A) Stannous fluoride

B) Neutral fluoride

C) Sodium silicofluroide

D) Sodium fluoride

A

D) Sodium fluoride

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

43
Q

What is the MOST frequently used compound for water fluoridation in the United States today?

A) Hydrofluosilicic acid

B) Sodium silicofluoride

C) Sodium fluoride

D) Stannous fluoride

A

A) Hydrofluosilicic acid

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.

44
Q

How do water fluoridation systems prevent excess water fluoridation?

A) A limited amount of fluoride is maintained in day tanks.

B) Proper controls are used to feed fluoride from the hoppers to distilling tanks.

C) Metering pumps

D) All of the above

A

D) All of the above

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.

45
Q

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?

A) Hypofluoridation

B) Hyperfluoridation

C) Excessive fluorosis

D) Community fluoridation

A

B) Hyperfluoridation

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.

46
Q

Why is the fluoridation cost per person lower in larger communities and higher in smaller communities?

A) Inverse relationship

B) Reverse relationship

C) Direct relationship

D) Indirect relationship

A

A) Inverse relationship

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

47
Q

What is salt fluoridation?

A) It is the addition of salt and fluoride to water.

B) These components are added to preserved food.

C) These components are added to table salt.

D) Patients get daily fluoride intake through salt blocks

A

C) These components are added to table salt.

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

48
Q

What three systems are used for water fluoridation distrubution in the United States?

A
  1. sodium fluoride
  2. sodium fluorosilicate, and
  3. hydrofluorsilicic acid (also known as fluorosilicic acid)
