Questions & Correct Answers | Graded A+
1. What level of prevention is associated with water fluoridation?
Quaternary prevention
Primary prevention
Secondary prevention
Tertiary prevention
2. Healthy education belongs to which level of oral disease prevention?
primary prevention
secondary prevention
quaternary prevention
none of the above
tertiary prevention
3. Describe the role of the dependent variable in the context of evaluating oral
health programs.
The dependent variable is used to control for external influences.
The dependent variable reflects the outcomes or effects of the oral
health programs being assessed.
The dependent variable is the factor manipulated by researchers.
The dependent variable is unrelated to the study's objectives.
4. Describe the significance of using an independent t-test in evaluating dental
health programs.
, The independent t-test measures the same group's performance over
different time periods.
The independent t-test is used to analyze the relationship between
two categorical variables in dental health.
The independent t-test helps determine if there is a statistically
significant difference in mean scores between two groups, which is
crucial for assessing program effectiveness.
The independent t-test evaluates the variance among multiple dental
health programs.
5. A dental hygienist is creating an oral health care program for participants in
the local women , infants, and children program (WIC). The hygienist will
develop a community profile to determine WICs participants dental
knowledge. instruction will include toothbrushing, oral physiotherapy
techniques, and the relationship between diet and dental decay. The program
will be offered for one month on days participants pick up food vouchers. By
offering instruction at the WIC site, the dental hygienist hopes to educate
caregivers and children early enough to prevent dental decay. Which level of
prevention does the oral health care program address?
Quaternary
Secondary
Tertiary
Primary
6. What is the primary purpose of using an independent t-test in dental health
studies?
To assess the relationship between two categorical variables.
To evaluate the mean scores of the same group over time.
To compare the mean scores of two different groups.
, To analyze the variance among multiple groups.
7. What does the notation p<.01 signify in statistical analysis?
A high probability of error
No significant difference
A low sample size
A statistically significant result
8. Which of the following systemic fluoride delivery methods would be
considered most cost effective?
Community water fluoridation
Professional fluoride treatment
Naturally occurring from foods
Dietary fluoride supplements
9. What is typically defined as the independent variable in a research study?
The variable that is manipulated or controlled by the researcher.
The variable that is measured or observed.
The variable that remains constant throughout the study.
The variable that is influenced by the independent variable.
10. A community fair was held to provide information to residents regarding
issues related to dental health. The dental hygienists organizing the event
wanted to determine if the fair had an impact on the attendees' dental
knowledge. Attendees were asked to complete a questionnaire prior to
visiting five booths and immediately following attendance at the last booth.
Ninety-three attendees voluntarily chose to complete the survey. The survey
