radiography is recommended so that:

b.
the technology improves horizontal angulation
c.
cone cuts don’t occur
d.
the technique is
more comfortable to the patient
2. A molar bitewing should image no more than the distal
of the mandibular second premolar.
a. True
b. False
3. The correct vertical angulation to use with a bitewing
is:

c. -10 degrees
d. -20 degrees
4. Vertical bitewings are indicated when there is ___ mm
of periodontal pocketing.
a. 3
b. 4
c. 5

5. The use of bitewing tabs requires all EXCEPT:
a. freehand alignment of the beam to the receptor
b.
the use of rectangular collimation
c.
the use of circular collimation
d.
presetting the vertical angulation to +10 degrees
6. A bitewing radiograph that exhibits unequal amounts
of alveolar bone in each of the arches is most likely a
result of:
a. incorrect vertical angulation
b. incorrect horizontal angulation
c. Both a and b
d. None of the Above
7. A molar bitewing radiograph that displays a partial
third molar, most likely is a result of:

d. All of the Above
e. None of the Above
9. If the mesial of the first premolar is not imaged on
the projection and there is no horizontal overlap, then
the most likely cause for the missing mesial of the
premolar is:

d. None of the Above
10. Using the SLOB rule, determine the cause of the
horizontal overlap in the maxillary premolar area in
this radiograph.
