Question 1
Dental trauma seen in children ages one to three is commonly caused by or attributed to
CORRECT ANSWER
underdeveloped motor coordination skills.
Question 2
Which of the following is the recommended treatment for a posterior primary tooth with
a draining abscess, no mobility, no radiographic furcal bone loss, and roots that are
completely intact?
CORRECT ANSWER
Pulpectomy
Question 3
When is pulpectomy indicated in primary teeth?
CORRECT ANSWER
Pulpectomy is indicated for cases in which there is no tooth mobility but the infection
might already have reached the pulp.
Question 4
___________ is indicated for primary teeth having suffered accidental pulp exposure or a
bacterial attack that only affects the coronal portion of the pulp.

,CORRECT ANSWER
pulpotomy
Question 5
T/F - indirect pulp capping is indicated for primary teeth
CORRECT ANSWER
FALSE - Indirect pulp capping is not indicated for primary teeth but is used for permanent
teeth with a cavity or caries approximating the pulp.
Question 6
Which of the following describes the best management strategy for an instrument that is
separated in the apical third after cleaning and shaping have occurred?
CORRECT ANSWER
Do not attempt to remove and proceed then to obturation.
Question 7
If an instrument separates at the filling or obturation stage, the instrument does not
require removal, because the etiology of the problem has already been resolved through
cleaning and shaping of the canals.
Question 8
A marked reduction in the size of a periapical radiolucency can be expected by which of
the following after a root canal procedure is completed?
CORRECT ANSWER

, one year
Periapical bone regeneration usually occurs at a rate of about 1.2 mm² per month,
gradually reducing the size of the periapical lesion.
Question 9
When instrumenting the mesial root of tooth #19, which canal surface is the most likely to
become strip-perforated?
CORRECT ANSWER
Distal
Question 10
The mesial surface of the distal root and the distal surface of the mesial root in the
mandibular first molar have a root concavity, making the dentin walls very thin.
Overenthusiastic root canal instrumentation (overcutting) can lead to strip perforations in
these areas and should be avoided.
Question 11
Which of the following steps should be taken initially to ensure the successful replantation
of a maxillary central incisor in a 13-year-old patient?
CORRECT ANSWER
Reposition and splinting only.
tooth should be splinted until it is stable and then necessary treatments can be done.
