EXAM REVIEW GRADED A+.
⫸ Epidemic. Ans: A disease that increases in prevalence beyond the
expected level is ____________.
⫸ Subjects are randomly chosen from a previously subdivided
population. Ans: What is a characteristic of stratified sampling?
⫸ Initially increase the demand for dental services. Ans: It can safely be
assumed that the growth in dental prepayment plans in the US will
___________.
⫸ Prevalence. Ans: The formula below is descriptive of what
epidemiological rate?
# of existing cases of a disease/ total population
⫸ Both statements are false. Ans: Susceptibility to periodontitis
increases with age, but not as part of the aging process. Dentate or
partially dentate elderly persons are at an extreme risk for total tooth
loss. T or F
,⫸ First statement is true; second statement is false. Ans: Gingivitis
precedes periodontitis. Areas of the mouth affected by gingivitis will
most likely become affected in alter years by periodontitis.
⫸ Identify community needs. Ans: The first step in establishing a
community health program is to _____________.
⫸ Pilot study. Ans: Conducting a trial run of the planned study on a
small sample is the purpose of a/an ____________.
⫸ Stratified random sample. Ans: Subjects randomly chosen from a
previously subdivided population are an example of a
__________________.
⫸ def. Ans: What caries index applies to primary dentition?
⫸ First statement is prevalence of HIV; second statement is incidence of
HIV. Ans: There are 10 million HIV positive patients worldwide. A new
case occurs every 15-20 seconds.
⫸ Health department. Ans: At the local level, which of the following
should be contacted for resources and facilities for a dental health
screening program?
, ⫸ Most of the scores are between 7-9. Ans: A dental hygienist gives a
quiz to determine effectiveness of instruction. The mean score is 8 and
the standard deviation is 1. What interpretation can be made?
⫸ Incidence of dental caries. Ans: A survey was conducted to determine
how many new carious lesions develop during the school year in the
permanent teeth of 6th grade children. Results of the survey provide a
measure of what?
⫸ Both statements are true. Ans: Fluoridation has several mechanisms
for caries inhibition. Included are enhancement of remineralization of
enamel, inhibition of glycolysis, incorporation of fluoride into the
enamel hydroxyapatite crystal, and bacteriocidal action. T or F
⫸ 3, 8, 14, 19, 24, 30. Ans: The "Ramfjord teeth" commonly used to
simplify dental indexes include which teeth?
⫸ DMFT. Ans: If the major purpose of an epidemiologist's research is to
determine caries susceptibility as opposed to immediate treatment needs,
the best caries index to use is the ______.
⫸ Both statements are TRUE. Ans: Fluorides are stored in skeletal
tissues. Even when concentrations reach 8 ppm, no impairment in
general health can be detected. T or F
