Question 1

Approximately __% of Americans visit a dental office yearly.

Accepted Answer

Approximately 60% of Americans visit a dental office yearly.Cost is a major reason why people do not see a dentist.People often wait to visit a dentist only in emergencies.Financial barriers and geographic access have become reasons why people do not receive primary prevention.

Question 2

Which of the following is true of dental sealants?

Accepted Answer

Little increase has occurred among children in low-income populations.One goal of Healthy People 2010 was to have 50% of children receiving dental sealants on their permanent molars.According to the 1988 to 1994 baseline data,only 23% of 8-year-old children and 15% of 14-year-old adolescents had dental sealants on their permanent molars.

Accepted Answer

Administration for ACF,an agency of the Department of Health and Human Services,is responsible for 60 programs that provide assistance to needy children and families,including the administration of the Head Start program,which serves approximately 900,000 preschool children annually.

Question 5

Which of the following represents the correct sequence for the five-step lesson plan described by Gagliardi?
1)Guided practice activities
2)Anticipatory planning
3)Instruction/information
4)Closure
5)Objectives

Accepted Answer

The five-step lesson plan described by Gagliardi includes preparation,anticipatory planning,objectives,instruction/information,guided practice activities,and closure.

Question 6

For health education programs to be effective:

Accepted Answer

The participant must be actively involved in the learning process.The cognitive model alone (attitude + knowledge = behavior change)has been ineffective in producing change.Both internal and external factors should be considered in developing an oral health educational program.The outcome of the oral health educational process will be successful only if all factors are considered.

Question 7

Advantages of community water fluoridation over a community-based fluoride supplement program include:

Accepted Answer

The need for compliance over an extended period of time is a major procedural and economic disadvantage of community-based fluoride supplement programs.Although the total costs of the purchase of supplements and administration of a program are small compared with the installation and start-up costs associated with fluoridation equipment,the overall cost of supplements per child is much greater than the per capita cost of community water fluoridation.Community water fluoridation provides decay prevention and oral health benefits for the entire population.

Question 8

The mean annual per capita cost is lower in community water fluoridation systems for larger populations (>50,000)than it is for smaller populations (<10,000).The lifetime cost of fluoridation per person is less than the cost of one dental filling.

Accepted Answer

The mean annual per capita cost of community water fluoridation ranges from $0.68 for systems with a population greater than 50,000 to $3.00 for systems with fewer than 10,000 people.The lifetime cost of fluoridation per person is less than the cost of one dental filling.

Question 9

Which of the following offers the benefits of fluoride in a structured environment in communities where a public water source is not available or where community water fluoridation is undesired for various reasons?

Accepted Answer

School-based fluoride mouth rinse programs offer the benefits of fluoride in a structured environment.The mouth rinse program is administered by school personnel or volunteers on a weekly basis to participating children.The children rinse for 60 seconds with 10 mL of 0.2% sodium fluoride.

Question 10

Fluoride varnish:

Accepted Answer

Varnishes may be used to prevent root surface caries on adults with gingival recession.The varnish is applied by an operator,with a recommended twice-yearly reapplication for optimal benefit.The varnish is not intended to be permanent,like a sealant,but to hold the fluoride in contact with the tooth for a period of time.

Question 11

Establishment of a dental home begins no later than ___ year(s)of age and includes referral to dental specialists when appropriate.

Accepted Answer

Establishment of a dental home begins no later than 1 year of age.The dental home is the ongoing relationship between the dentist and the patient,inclusive of all aspects of oral health care delivered in a comprehensive,continuously accessible,coordinated,and family-centered way.

Question 12

Most dental educational programs have been implemented for:

Accepted Answer

Oral health education for children is a priority because of the high prevalence of dental caries in this group.If a society free of dental disease is the goal,educational programs must be targeted for the future of society-the children.

Question 13

To reach the Healthy People 2020 goal of increasing the proportion of children who have received dental sealants on their molar teeth,many states have instituted:

Accepted Answer

Many states have instituted SBSPs.In some programs,mobile dental vans are sent to schools,and the sealants are applied in the van.In other programs,portable equipment is transported from school to school and is set up in available space.

Question 14

The total population receiving community water fluoridation was __% in 2006.

Accepted Answer

As of 2006,the total population receiving adjusted community water fluoridation was 61.5%,up from 57.6% in 2000.Approximately 184 million U.S.residents currently benefit from community water fluoridation.The target is 75% of the population.

Question 15

The average number of decayed,missing (because of caries),or filled permanent teeth (DMFT)steadily declined from 1967 to 1992 in the United States because of:

Accepted Answer

The average number of DMFT steadily declined from 1967 to 1992 because of populations residing in fluoridated communities.

Question 16

The fastest growing segment of the population in the United States is:

Accepted Answer

Between 1990 and 1994,the number of older adults increased 11-fold.These people are now the fastest growing segment of the population in the United States.The Census Bureau projects that the number of persons age 65 years and older will more than double by the middle of the twenty-first century to approximately 80 million.

Question 17

Which of the following has been recognized as one of the top ten public health measures of the 20th century?

Accepted Answer

Fluoridation has been recognized as one of the top ten public health measures of the 20th century.As a result of the general availability of public water sources to most people,the adjustment of the natural fluoride content found in the water to levels optimal for combating oral disease has proven to be a successful public health measure.

Question 18

Which of the following is the most cost-effective,most practical,and safest means of preventing tooth decay?

Accepted Answer

Even though other sources of fluoride are available and despite the increased risk of fluorosis,community water fluoridation remains the most cost-effective,the most practical,and the safest means of preventing tooth decay.

Question 19

Which of the following is true regarding antifluoridationists?

Accepted Answer

Antifluoridationists provide inaccurate false information to the public and to elected officials and attempt to link adverse health effects with fluoridation.Their arguments against fluoridation do not have any merit based on scientific knowledge.The economic and health benefits of fluoridation for millions of Americans have been confirmed in numerous studies by renowned scientists.

Question 20

The recommended levels for water fluoridation in the United States range from 0.7 to 1.2 parts per million (ppm)of fluoride,depending on the:

Accepted Answer

The recommended levels for water fluoridation depend on the average daily temperature for that area.This range is based on the hypothesis that water consumption increases with increasing climatic temperature.This assumption may not be as accurate as earlier research indicates because of the increased use of air conditioning and the increased consumption of soft drinks and bottled water.
