ADEX DSE Dentistry Exam Prep:
Remembered Questions & Answers
(Latest 2025/2026) – Graded A+
Q1. Clinical picture of a 14-year-old patient with generalized inflamed, boggy
gingiva that bleeds easily. What is the most likely diagnosis?
• A) Gingivitis
• B) Periodontitis
• C) Leukemia
• D) ANUG
Correct ,,,answer,,,: C
Rationale: Acute gingival inflammation in a young patient, especially when the
gingiva appears boggy and bleeds easily, can be a presenting sign of acute
monocytic or acute myeloid leukemia. Gingival infiltration by leukemic cells
causes characteristic swelling and bleeding. This is a classic "red flag" presentation
on the DSE .
Q2. A patient presents with an allergic reaction to a barbiturate on the lip.
What medication should be administered?
• A) Epinephrine
• B) Prednisone
• C) Benadryl (Diphenhydramine)
, • D) Albuterol
Correct ,,,answer,,,: C
Rationale: For a mild-to-moderate allergic reaction without airway compromise,
an antihistamine such as diphenhydramine (Benadryl) is the appropriate treatment.
Epinephrine is reserved for anaphylaxis with respiratory distress or hypotension .
Q3. A patient does not like the appearance of a canine tooth (pictured). The
tooth shows small, pitted, discolored areas on the enamel surface. What is this
condition?
• A) Amelogenesis Imperfecta
• B) Enamel Hypoplasia
• C) Dental Fluorosis
• D) Turner's Tooth
Correct ,,,answer,,,: B
Rationale: The description of localized pitted, discolored areas on enamel is
characteristic of enamel hypoplasia—a defect in enamel formation that can result
from trauma, infection, nutritional deficiencies, or genetic factors. Unlike
amelogenesis imperfecta (which affects all teeth), hypoplasia may be localized to
one or a few teeth .
Q4. A patient has facial erosion of enamel due to acidic beverages. What
radiographic appearance would be expected?
, • A) Thin, pitted enamel with normal dentin
• B) Generalized thin enamel with normal root structures
• C) Normal enamel with interproximal radiolucencies
• D) Missing enamel on facial surfaces with normal lingual enamel
Correct ,,,answer,,,: D
Rationale: Acid erosion from beverages (e.g., soda, citrus juices) typically affects
the facial surfaces of anterior teeth due to the swallowing pattern.
Radiographically, you would see thinner or missing enamel on the facial aspect
with relatively preserved lingual enamel. This is a classic presentation on the DSE .
Q5. A panoramic radiograph shows "ghost teeth"—teeth with thin enamel,
small size, and abnormal shape. What is the diagnosis?
• A) Dentinogenesis Imperfecta
• B) Amelogenesis Imperfecta
• C) Regional Odontodysplasia
• D) Dentin Dysplasia
Correct ,,,answer,,,: C
Rationale: "Ghost teeth" is the classic radiographic description of Regional
Odontodysplasia. The affected teeth appear faint or "ghost-like" on radiographs
because the enamel and dentin are hypomineralized and thin. This condition
typically affects a localized group of teeth in one quadrant .
, Q6. A patient is shown with blue sclera in an eye picture. What dental
findings should you expect to see?
• A) Amelogenesis Imperfecta
• B) Dentinogenesis Imperfecta
• C) Enamel Hypoplasia
• D) Fluorosis
Correct ,,,answer,,,: B
Rationale: Blue sclera is a classic extraoral finding in Dentinogenesis
Imperfecta (often associated with Osteogenesis Imperfecta). The dental findings
include opalescent, translucent, blue-gray or brownish teeth with bulbous crowns,
cervical constriction, and obliterated pulp chambers. This is a highly tested
association on the DSE .
Q7. All of the following are symptoms of hyperthyroidism EXCEPT:
• A) Fatigue
• B) Exophthalmos
• C) Tachycardia
• D) Tremor of extremities
Correct ,,,answer,,,: A
Rationale: Hyperthyroidism causes increased metabolic rate, resulting in weight
loss (not gain), heat intolerance, tachycardia, exophthalmos (bulging eyes), tremor,
and anxiety. Fatigue is more characteristic of hypothyroidism, not
hyperthyroidism. This "except" question appears frequently .
