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 federal department overseas the women, infants and children (WIC) program ? -CORRECT

Which type of data is gathered when WIC participants are asked? "Describe how you brush your child's
teeth?" -CORRECT ANSWERS- qualitative
qualitative data describes, rather than measures, information. A variable is associated with research and

these numerical data represent counts or measurements
The statement, "The oral health care program will improve the dental health of women and their
children, "is an example of the program -CORRECT ANSWERS- Goal
A goal is a broadly-based statement of what changes will occur as a result of the program. An objective
is a specific statement that describes, in a measurement manner, the desired outcomes from program

Case 2 -CORRECT ANSWERS- 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 - trust swallowing.
Occlusion was determined using Angle's classification of malocclusion. The overjet 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 determined that with p < 0.05, overjet
measurements were significantly increased in persons with tongue - thrust when compared to persons
who did not have tongue -thrust
Which study was conducted? -CORRECT ANSWERS- clinical trail
a clinical trial is a study to test a hypothesis. It is used to establish cause&effect relationships. In a cohort
study, a well-defined group (cohort) is observed over time to determine the natural progression of a
disease or condition. Case-control occurs when 2 groups are compared, 1 group with a disease or
condition (cases) and a second group without it (controls), to identify factors in their history that can be
associated with the disease or condition. A cross-sectional study represents a cross-section of the
population at one point at a time.
which sampling technique was used to selvt the subjects? -CORRECT ANSWERS- Purposive
purposive (or judgmental) sampling provides a sample of subjects who would be most representative of
the opulation. Random sampling occurs when each member of a population has an equal chance of
being included. In stratified sampling, a population is divided into strata and subjects are randomly
selected from each stratum. Systematic sampling involves the selection of subjects by including everty
nth person on a list
