A dental hygienist is creating an oral health care program for participants at
a local Women, Infants, and Children program (WIC). The hygienist will
develop a community profile to determine the WIC participant's 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. -
ANSWER Agriculture
Which describes WIC historical data used to develop the community
profile? -ANSWER Secondary
Which type of data is gathered when WIC participants are asked, "Describe
how you brush your child's teeth." -ANSWER Qualitative
Qualitative data describes, rather than measures, information.
The statement, "The oral health care program will improve the dental health
of women and their children," is an example of the program... -ANSWER
goal
Which level of prevention does the oral health care program address? -
ANSWER Primary
Which provides information to parents on child development stages so the
child's oral health needs can be adequately met? -ANSWER Anticipatory
guidance
, An orthodontist hypothesizes a relationship exists between tongue thrust
swallowing and the position of anterior teeth. He conducts a study by
selecting 35 subjects who have tongue thrust swallowing and a control
group of 35 subjects without tongue-thrust swallowing. Occlusion was
determines using Angle's classification of malocclusion. The overate of
those who had tongue thrust were measured and compared with the
corresponding values of the control subjects. The same orthodontist
performed all measurements. Results determines that with p < 0.05,
overate measurements were significantly increased in persons with tongue-
thrust when compared to persons who did not have tongue-thrust.
Which study was conducted? -ANSWER Clinical trial
Which sampling technique was used to select the subjects? -ANSWER
Purposive
In this study, which was the independent variable? -ANSWER Tongue-
thrust swallowing
In this study, which important aspect was achieved by using only one
examiner? -ANSWER Intra-examiner reliability
Which statistical test is used to test the mean scores of the two groups? -
ANSWER Independent t-test
Referring to occurrence by chance alone, what does p< .05 indicate? -
ANSWER 5% or less probability
A community fair was held to provide information to residents regarding
issue related to dental health. The dental hygienists organizing the event
wanted to determine if the fair had an impact on the attendees' dental
knowledge. Attendee were asked to complete a questionnaire prior to
visiting five booths and immediately following attendance at the last booth.
93 attendees voluntarily chose to complete the survey. The survey was a
10-item dental health knowledge questionnaire with each item worth one
point. It was administered in a pre and post test design. Questionnaire
items were in a true or false format. Each item was scored "1" of answered
correctly and "0" if answered incorrectly. Items were totaled and overall
pre-test scores were compared with overall post-test scores. A statistical
