SECTION 1: PATIENT ASSESSMENT & DIAGNOSIS Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 58-year-old male presents to your clinic for a routine six-month recall. He reports no
pain but mentions occasional bleeding when brushing his lower anterior teeth. His
medical history is significant for well-controlled hypertension managed with lisinopril.
Clinical examination reveals generalized 3–4 mm periodontal pockets, moderate
calculus on the lingual surfaces of teeth #23–26, and a 4 mm diameter white patch on
the left buccal mucosa that cannot be wiped off and has been present for three weeks.
What is the most appropriate next step in management?
A. Prescribe a chlorhexidine rinse and schedule a two-week follow-up to reassess the
mucosal patch
B. Immediately perform an incisional biopsy of the buccal mucosal patch without delay
C. Obtain a thorough history of the lesion including duration and risk factors, then
schedule a two-week follow-up to reassess ✓ CORRECT
,D. Refer the patient to a periodontist for full-mouth scaling and root planing before
addressing the mucosal patch
Correct Answer: C
Rationale: A persistent white patch of unknown etiology in a patient with risk factors
requires a detailed history and short-term observation to differentiate between frictional
keratosis and a potentially dysplastic lesion. Immediate biopsy is not indicated without
first establishing a reasonable observation period for an innocuous-appearing
three-week lesion. A two-week follow-up allows the clinician to assess for resolution if
the cause is traumatic while ensuring timely escalation if the lesion persists.
Question 2 of 50
A 34-year-old female arrives for an emergency visit complaining of sharp, spontaneous
pain in her maxillary right quadrant that worsens with cold stimuli and lingers for several
minutes after stimulus removal. She denies recent trauma. Radiographic examination
reveals a deep restoration on tooth #4 with no periapical radiolucency. Cold testing
elicits an exaggerated, prolonged response compared to the contralateral canine. The
tooth is not sensitive to percussion or palpation. What is the most likely pulpal
diagnosis?
A. Reversible pulpitis with symptomatic apical periodontitis
B. Symptomatic irreversible pulpitis ✓ CORRECT
C. Normal pulp with referred pain from the maxillary sinus
D. Necrotic pulp with chronic apical abscess
Correct Answer: B
Rationale: Spontaneous pain and lingering thermal sensitivity in the absence of
periapical changes are classic indicators of symptomatic irreversible pulpitis. The
exaggerated but non-lingering response seen in reversible pulpitis does not match the
,prolonged post-stimulus pain described here. A necrotic pulp would not respond to cold
testing at all, making this diagnosis inconsistent with the clinical findings.
Question 3 of 50
During a new patient examination, a 42-year-old male with type 2 diabetes reports that
his last dental visit was four years ago. Extraoral examination reveals bilateral palpable
lymph nodes in the submandibular region, each approximately 1.5 cm in diameter,
mobile, and non-tender. Intraoral examination shows multiple carious lesions,
generalized moderate plaque accumulation, and a draining sinus tract on the buccal
aspect of tooth #19. What is the most likely explanation for the lymphadenopathy?
A. Metastatic spread from a primary oral squamous cell carcinoma
B. Reactive lymphadenopathy secondary to chronic dental infection ✓ CORRECT
C. Lymphoma presenting with bilateral submandibular involvement
D. Sialolithiasis causing secondary lymph node enlargement
Correct Answer: B
Rationale: Bilateral, mobile, non-tender lymph nodes in the presence of a draining sinus
tract and multiple active dental infections are most consistent with reactive
lymphadenopathy. Metastatic carcinoma or lymphoma typically presents with fixed,
matted, or rapidly enlarging nodes that are often unilateral. Sialolithiasis would more
likely cause glandular swelling and pain during salivation rather than isolated lymph
node enlargement.
Question 4 of 50
A 67-year-old female presents for evaluation of a non-healing ulcer on the lateral border
of her tongue. She first noticed it eight weeks ago and assumed she had bitten herself.
She has a 40 pack-year smoking history and consumes alcohol daily. The ulcer is
indurated, measures approximately 1.2 cm, and has raised everted margins. What is the
most appropriate immediate management?
, A. Prescribe a topical corticosteroid and reevaluate in four weeks
B. Order a panoramic radiograph to evaluate for underlying bony involvement
C. Perform an incisional biopsy from the ulcer margin and center ✓ CORRECT
D. Initiate a two-week course of systemic antibiotics and reassess
Correct Answer: C
Rationale: An indurated, non-healing ulcer with everted margins in a patient with heavy
tobacco and alcohol use warrants immediate biopsy to rule out squamous cell
carcinoma. Topical corticosteroids or antibiotics are inappropriate for suspected
malignancy and would only delay definitive diagnosis. A panoramic radiograph does not
evaluate soft tissue pathology and is not indicated as the first step for a mucosal ulcer
without bony symptoms.
Question 5 of 50
A 29-year-old male presents with a two-day history of facial swelling and pain. He
reports a dull ache in tooth #14 for the past month that recently worsened. Extraoral
examination reveals diffuse swelling of the left midface with erythema extending to the
lower eyelid. The patient is febrile at 101.2°F and reports difficulty looking upward with
his left eye. What is the most immediate concern?
A. Maxillary sinusitis requiring antibiotic therapy and decongestants
B. Orbital cellulitis secondary to an odontogenic infection ✓ CORRECT
C. Allergic angioedema that may compromise the airway
D. Acute herpes zoster involving the maxillary division of the trigeminal nerve
Correct Answer: B
Rationale: Diffuse facial swelling with ocular symptoms including pain on upward gaze
and fever in the setting of a non-vital maxillary tooth strongly suggests orbital cellulitis,
a vision-threatening emergency. Sinusitis alone would not typically cause restricted
extraocular movement or periorbital swelling of this severity. The presence of a chronic
