SZABMU MDS Part 1: Oral Pathology & Oral Medicine MCQs With Explanations

Sample Oral Pathology and Oral Medicine MCQs for SZABMU MDS Part 1 prep, with explanations -- two of the dental-specific subjects most under-covered by generic dental guides.

SZABMU MDS Part 1 shares a basic-sciences core with the MD/MS stream but also tests dental-specific subjects. This page covers two of the bank's substantial dental subjects -- Oral Pathology and Oral Medicine -- with sample MCQs and explanations.

Why Oral Pathology and Oral Medicine

Most MDS candidates spend the bulk of their prep time on anatomy, physiology and pharmacology, since those subjects are shared with MD/MS Part 1. Oral Pathology and Oral Medicine are the dental-specific subjects that only MDS candidates are tested on in depth, and they are exactly the subjects generic MD/MS-oriented study material tends to skip.

Sample Oral Pathology MCQs

1. The most common odontogenic cyst is the:

A) Dentigerous cyst
B) Radicular (periapical) cyst ✅
C) Odontogenic keratocyst
D) Lateral periodontal cyst

The radicular cyst arises from epithelial rests of Malassez in a periapical granuloma secondary to pulp necrosis, and it is by far the most common odontogenic cyst encountered clinically.

2. Ameloblastoma most commonly occurs at which site?

A) Anterior maxilla
B) Posterior mandible (angle/ramus) ✅
C) Hard palate
D) Floor of the mouth

The majority of ameloblastomas arise in the posterior mandible, particularly the angle and ascending ramus, and typically show the classic multilocular "soap bubble" radiographic appearance.

3. Which is the most common odontogenic tumour overall?

A) Ameloblastoma
B) Odontoma ✅
C) Ameloblastic fibroma
D) Odontogenic myxoma

Odontomas (compound and complex) are hamartomatous lesions and are, overall, the most frequently diagnosed odontogenic tumours.

Sample Oral Medicine MCQs

4. The most common oral mucosal lesion seen in clinical practice is:

A) Oral lichen planus
B) Recurrent aphthous stomatitis ✅
C) Leukoplakia
D) Oral candidiasis

Recurrent aphthous stomatitis (common "canker sores") is the most frequently encountered oral mucosal condition, typically presenting as painful, shallow, round-to-oval ulcers with a yellow-grey floor and erythematous halo.

5. Oral lichen planus classically presents with which clinical feature?

A) Unilateral verrucous plaque
B) Bilateral white striae on the buccal mucosa (Wickham's striae) ✅
C) Solitary pigmented macule
D) Vesicles that rupture into deep ulcers only on the palate

Oral lichen planus most often shows bilateral, lace-like white striae (Wickham's striae) on the buccal mucosa, sometimes with erythematous or erosive areas.

6. Leukoplakia is best defined as:

A) Any red patch on the oral mucosa
B) A white patch that rubs off easily
C) A white patch/plaque that cannot be rubbed off and cannot be characterised as any other condition ✅
D) A fungal infection of the tongue

Leukoplakia is a clinical diagnosis of exclusion -- a white patch that cannot be scraped off and cannot be attributed to any other identifiable disease -- and it is considered a potentially malignant oral disorder requiring biopsy when indicated.

How to Use These Questions

Since Oral Pathology and Oral Medicine carry real weightage but are often under-revised relative to anatomy and physiology, treat a wrong answer here as a priority flag, not a minor slip. Drill each subject as its own timed block before mixing it into full-length mocks.
