1. A 45-year-old patient with a history of type 2 diabetes presents for a comprehensive dental examination.
Which of the following findings is most indicative of poor glycemic control and requires immediate medical
consultation before proceeding with non-emergency dental treatment?
A. Xerostomia and fissured tongue
B. Generalized gingival enlargement
C. Presence of multiple periapical radiolucencies
D. Fruity, acetone-like breath odor
Correct Answer: D. Fruity, acetone-like breath odor
Rationale: A fruity or acetone-like breath odor is a classic sign of diabetic ketoacidosis (DKA), a life-threatening acute
complication of diabetes mellitus. This indicates severe hyperglycemia and requires immediate medical intervention to
stabilize the patient before any elective dental procedure. Xerostomia (A) and periapical radiolucencies (C) are common
chronic findings associated with diabetes. Gingival enlargement (B) is more commonly associated with medications like
phenytoin or calcium channel blockers, though it can be seen in other conditions; it is not an acute indicator of poor
control.
,2. When performing a pulp vitality test using an electric pulp tester, what is the most critical step to ensure an
accurate reading and avoid patient discomfort?
A. Applying a conductive medium to the tooth surface
B. Placing the tip on the incisal edge of the tooth
C. Allowing the patient to hold the ground wire
D. Increasing the current gradually until the patient responds
Correct Answer: D. Increasing the current gradually until the patient responds
Rationale: The current on an electric pulp tester must be increased slowly from zero to avoid startling the patient and
to accurately determine the threshold at which the pulp responds. This gradual increase provides a more reliable and
comfortable assessment. A conductive medium (A) is necessary to ensure contact but is not the most critical step for
accuracy. The tip should be placed on the cervical or middle third of the tooth (B), not the incisal edge. While the
patient holding the ground wire (C) completes the circuit, the gradual increase is paramount for a valid and
comfortable test.
3. A patient presents with a deep, carious lesion on tooth #19. The cavity is excavated, and a pinpoint exposure of
the pulp is noted, with visible bleeding. Which of the following is the most appropriate immediate management?
,A. Direct pulp capping with calcium hydroxide
B. Indirect pulp capping with glass ionomer cement
C. Root canal therapy
D. Placement of a sedative temporary filling
Correct Answer: C. Root canal therapy
Rationale: A carious exposure with bleeding indicates a direct pulp exposure where the pulp is inflamed and necrotic
tissue may be present. The standard of care for a carious exposure is root canal therapy to remove the irreversibly
damaged pulp and prevent apical periodontitis. Direct pulp capping (A) is generally reserved for mechanical exposures
(e.g., traumatic) in a healthy, asymptomatic pulp. Indirect pulp capping (B) is for deep caries near the pulp but without
an actual exposure.
4. In the context of antibiotic prophylaxis for infective endocarditis, which of the following cardiac conditions is
classified as the highest risk and requires premedication before dental procedures that involve manipulation of
gingival tissue or perforation of the oral mucosa?
A. Mitral valve prolapse without regurgitation
B. Bicuspid aortic valve
, C. A prosthetic cardiac valve
D. Hypertrophic cardiomyopathy
Correct Answer: C. A prosthetic cardiac valve
Rationale: The 2021 AHA guidelines identify prosthetic cardiac valves, including transcatheter-implanted prostheses, as
the highest-risk category for developing infective endocarditis. This warrants antibiotic prophylaxis. Mitral valve
prolapse without regurgitation (A), bicuspid aortic valve (B), and hypertrophic cardiomyopathy (D) are no longer
considered high-risk conditions requiring routine prophylaxis for dental procedures according to current guidelines.
5. A dentist is reviewing radiographic images. A well-demarcated, unilocular radiolucency is observed between
the roots of the mandibular premolars. It appears to be corticated and is associated with an unerupted tooth.
What is the most likely diagnosis?
A. Ameloblastoma
B. Periapical granuloma
C. Odontogenic keratocyst
D. Dentigerous cyst
Correct Answer: D. Dentigerous cyst
