The protocol for dental trauma involves all of the following, except
a. Ideally, the tooth should be repositioned to its original position.
b. EPT and thermal testing are unreliable following trauma since physical
trauma can severe or damage nerve supply without altering pulpal blood
supply/vitality.
c. If the root is completely formed on a tooth that has been intruded, a
pulpectomy should be performed within 1-3 weeks after the injury.
d. The tooth should be splinted for 2 to 4 months if it sustains a root fracture -
correct answer ✔d. The tooth should be splinted for 2 to 4 months if it
sustains a root fracture
When evaluating horizontal root fractures, one should consider all as being
true, except:
A. Chances of coronal root fractures healing are similar to mid-root or apical
fractures if the fracture is below the height of crestal bone and properly
splinted
B. If the fracture is at or coronal to the crest of the alveolar bone, the
prognosis is still favorable
C. Pulpal necrosis occurs in 25% of root fractures
D. In the vast majority of cases, necrosis occurs in the coronal segment only
with the apical segment remaining vital - correct answer ✔B. If the fracture is
at or coronal to the crest of the alveolar bone, the prognosis is still favorable
How long should horizontal root fractures be splinted if the coronal section
was displaced and repositioned?
,A. not indicated
B. 7 to 10 days
C. 4 to 6 weeks
D. 3 months - correct answer ✔C. 4 to 6 weeks
Which of the following techniques is the best way to detect a vertical root
fractures?
A. Periapical Film
B. Panograph
C. CAT Scan
D. Occlusal Film - correct answer ✔C. CAT Scan
Patient presents for emergency dental exam after falling off his bike and face
planted into sidewalk. Upon examination, you suspect that he may have a root
fracture of #8. How many angled PA radiographs would you take, at a
minimum?
A. Two angled films at 45 and 90 degrees to the possible fracture line
B. Only one film from the distal or mesial at 45 degree to uphold ALARA,
C. Three angled films at 45, 90 and 110 degrees to ensure at least one
passes through the possible fracture line
D. Two angle films at any angle as long as it is parallel to the long axis of the
root and will reveal the fracture line. - correct answer ✔C. Three angled films
at 45, 90 and 110 degrees to ensure at least one passes through the possible
fracture line
Assessment of a completed NSRCT is based primarily on what?
,A. Radiographic examination
B. Pain level of the patient
C. Mobility of the tooth
D. EPT results
E. The alignment of the planets - correct answer ✔A. Radiographic
examination
Research has demonstrated that the average distance from the foramen to
the minor constriction is:
a. 0.5 -1.0mm
b. 0.2-0.4mm
c. 1.0-2.0mm
d. 2.0-3.0mm - correct answer ✔a. 0.5 -1.0mm
Which of the following diagnostic tests is (are) not an indication of pulp
vitality?
1. Percussion
2. Mobility
3. Thermal (hot and cold)
A. 1 only
B. 3 only
C. 1 and 2
D. 2 and 3
E. all of the above - correct answer ✔C. 1 and 2
, Which of following is false with respect to the use of electric pulp testing in
endodontics?
A. The technology is not accurate enough at this time to be utilized on a
routine basis in a clinical setting.
B. The response of the pulp to electric testing reflects the histologic health or
disease status of the pulp.
C. A response by the pulp to the electric current only denotes that some viable
nerve fibers are present in the pulp and are capable of responding.
D. Electric pulp test results are most accurate when no response is obtained
to any amount of current (i.e. necrotic pulp). - correct answer ✔B. The
response of the pulp to electric testing reflects the histologic health or disease
status of the pulp.
To date, the most accurate pulp test that are used to determine if a tooth's
pulp is healthy is/are
a. Cold
b. Heat
c. EPT
d. Both a and b
e. Both a and c - correct answer ✔e. Both a and c
When applying the tube shift technique, buccal object rule, Clark's rule, or the

objects that have been superimposed
