3. The most common cause of spontaneous abortion is __________.
A. immune suppression due to a shift in helper T cell type dominance
B. morphologic or chromosomal abnormalities that prevent successful implantation
C. the development of gestational diabetes
D. a benign systolic ejection murmur in the mother
ANS: B
Morphologic or chromosomal abnormalities that prevent successful implantation are the
most common cause. It is most unlikely that any dental procedure would be implicated in
spontaneous abortion, provided fetal hypoxia and exposure of the fetus to teratogens are
avoided.
PTS: 1 REF: p. 272
4. Which of the following is the safest period during which to provide routine dental care
for the pregnant patient?
A. the first trimester
B. the second trimester
C. the third trimester
D. the immediate postpartum period
ANS: B
The second trimester is the safest period during which to provide routine dental care.
Emphasis should be placed on controlling active disease and eliminating potential
problems that could occur later in pregnancy or during the immediate postpartum period,
because providing dental care during these periods is often difficult. Other than as part of
a good plaque control program, elective dental care is best avoided during the first
trimester because of the potential vulnerability of the fetus. The early part of the third
trimester is still a good time to provide routine dental care. After the middle of the third
trimester, elective dental care is best postponed.
PTS: 1 REF: p. 274
5. The gonadal/fetal dose incurred with two periapical dental films (when a lead apron is
used) is __________ that for 1 day of average exposure to natural background radiation
in the United States.
A. 700 times less than
B. 7 times less than
C. equal to
D. 7 times more than

, Test Bank 17-3
ANS: A
It is 700 times less than that for 1 day of average exposure to natural background
radiation in the United States. Despite the negligible risks of dental radiography,
radiographs should be obtained selectively and only when necessary and appropriate to
aid in diagnosis and treatment. To further reduce the radiation dose, the following
measures should be employed: rectangular collimation, E-speed or F-speed film or faster
techniques, lead shielding, high-kilovoltage (kV) or constant beams, and an ongoing
quality-assurance program for equipment and technique.
PTS: 1 REF: p. 275
6. What should a pregnant dental auxiliary or dentist do to protect herself and her baby from
potential fetal exposure to x-radiation?
A. Stay in a remote area of the dental office, and avoid locations where x-radiation is
utilized.
B. Wear a lead apron the entire time in the office, and avoid circumstances of
exposing x-ray films.
C. Utilize digital radiography rather than film-based radiography.
D. Wear a film badge, stand more than 6 feet from the tubehead, and position herself
at between 90 and 130 degrees of the beam, preferably behind a protective wall.
ANS: D
When these guidelines are followed, no clinical contraindication to operation of the x-ray
machine by pregnant women arises. However, dentists should familiarize themselves
with federal and state regulations that would supersede these guidelines.
PTS: 1 REF: p. 276
7. Which of the following is the analgesic of choice during pregnancy?
A. aspirin
B. acetaminophen
C. nonsteroidal anti-inflammatory
D. codeine
ANS: B
Acetaminophen is the analgesic of choice during pregnancy. Aspirin and nonsteroidal
anti-inflammatory drugs convey risks for constriction of the ductus arteriosus, as well as
for postpartum hemorrhage and delayed labor. The risk of these adverse events increases
when agents are administered during the third trimester. Codeine and propoxyphene are
associated with multiple congenital defects and should be used cautiously and only if
needed.
