Question 1
A 45-year-old patient presents with spontaneous, lingering pain
from the mandibular first molar. Cold testing produces severe
pain that persists for more than 30 seconds after removal of the
stimulus. Percussion is mildly positive. Which pulpal diagnosis is
most appropriate?
A. Normal pulp
B. Reversible pulpitis
C. Irreversible pulpitis
D. Pulp necrosis
Correct Answer: C. Irreversible pulpitis
The defining clinical feature is the severe, lingering response to
a thermal stimulus. Reversible pulpitis generally produces a
brief, non-lingering response that resolves shortly after the
,stimulus is removed. Symptomatic irreversible pulpitis
commonly presents with spontaneous pain, prolonged thermal
sensitivity, or pain that is difficult for the patient to localize. Mild
percussion sensitivity may indicate that the inflammatory
process has extended to the periodontal ligament, but it does
not change the primary pulpal diagnosis. Pulp necrosis would
generally produce no response to thermal or electrical pulp
testing.
Question 2
Which periodontal finding most directly distinguishes clinical
attachment loss from gingival recession alone?
A. Increased probing depth
B. Bleeding on probing
C. Apical displacement of the junctional epithelium with loss
of attachment
D. Gingival inflammation
Correct Answer: C. Apical displacement of the junctional
epithelium with loss of attachment
Clinical attachment loss represents the apical migration of the
periodontal attachment apparatus relative to a fixed reference
point, usually the cemento-enamel junction. Gingival recession
can expose root surfaces but does not by itself establish active
,or historical periodontal attachment loss unless the position of
the attachment has also changed. Probing depth and bleeding
on probing are useful clinical measurements, but neither alone
defines attachment loss.
Question 3
A patient taking warfarin requires a dental extraction. What is
the most appropriate initial approach?
A. Discontinue warfarin for five days without consultation
B. Replace warfarin with aspirin
C. Assess the current anticoagulation status and coordinate
management with the prescribing clinician when indicated
D. Proceed without reviewing medications
Correct Answer: C. Assess the current anticoagulation status
and coordinate management with the prescribing clinician
when indicated
Patients receiving anticoagulants should not have therapy
stopped arbitrarily because interruption may expose them to
significant thromboembolic risk. For many routine dental
procedures, local hemostatic measures allow treatment to
proceed without discontinuing anticoagulation. The clinician
should review the medication, indication, recent relevant
laboratory information when appropriate, procedure-related
, bleeding risk, and the patient's medical history. If modification is
being considered, it should be coordinated with the clinician
responsible for anticoagulation.
Question 4
Which radiographic appearance is most characteristic of early
proximal dental caries?
A. Uniform radiopacity below the contact
B. Triangular radiolucency within enamel or extending toward
dentin
C. Periapical radiopacity
D. Loss of the lamina dura around every tooth
Correct Answer: B. Triangular radiolucency within enamel or
extending toward dentin
Proximal caries typically appears radiographically as a
triangular or wedge-shaped radiolucency because of the
direction of demineralization through enamel and dentin. The
lesion may have its broadest dimension near the outer enamel
surface and progress toward the dentino-enamel junction, with
further progression into dentin. Radiographs are adjunctive
rather than a replacement for clinical examination.
