Oral Pathology MCQs
Oral Pathology MCQs cover the diseases affecting the oral cavity, including tumors, precancerous conditions, cysts, and inflammatory diseases. These quizzes help students of BDS and MDCAT assess their ability to diagnose and understand oral conditions and prepare for clinical scenarios.
Q: Papilloma is a benign tumor caused by

A) Acantholysis
B) Mitosis

✅ Correct Answer: D
Explanation: Verrucous carcinoma is a slow-growing variant of SCC with keratin-filled clefts.
Q: Verrucous carcinoma is best described as
A) Rapidly invasive and poorly differentiated
B) Slow-growing and well-differentiated
C) Non-keratinized and ulcerative
D) Metastasizing and aggressive

Q: Bence-Jones proteins are typically associated with
A) Paget’s disease
B) Osteomyelitis
C) Fibrous dysplasia
D) Multiple myeloma
✅ Correct Answer: D
Explanation: Bence-Jones proteins are light chains found in urine and are indicative of plasma cell malignancies like multiple myeloma.
Q: A “cotton wool” appearance on radiograph is indicative of
A) Cemento-osseous dysplasia
B) Fibrous dysplasia
C) Osteosarcoma
D) Paget’s disease
✅ Correct Answer: D
Explanation: Paget’s disease of bone often shows patchy radiopacities resembling cotton wool due to abnormal bone remodeling.
Q: Presence of ghost cells is a characteristic of
A) Periapical granuloma
B) Dentigerous cyst
C) Lateral periodontal cyst
D) Calcifying odontogenic cyst
✅ Correct Answer: D
Explanation: Calcifying odontogenic cysts show ghost cells, which are enlarged eosinophilic cells without nuclei, indicative of abnormal keratinization.
Q: A lesion located in the midline of the hard palate with pseudoepitheliomatous hyperplasia suggests
A) Inflammatory papillary hyperplasia
B) Necrotizing sialometaplasia
C) Nicotine stomatitis
D) Median rhomboid glossitis
✅ Correct Answer: B
Explanation: Necrotizing sialometaplasia presents as a deep ulcer due to ischemic necrosis of minor salivary glands, often in the hard palate.
Q: Tooth floating in air appearance is commonly seen in
A) Fibrous dysplasia
B) Radicular cyst
C) Langerhans cell histiocytosis
D) Ameloblastoma
✅ Correct Answer: C
Explanation: Langerhans cell histiocytosis can destroy bone around teeth, giving a radiographic impression of “floating” teeth.
Q: Chronic desquamative gingivitis is commonly a manifestation of
A) Hemangioma
B) Apthous ulcers
C) Leukoplakia
D) Lichen planus
✅ Correct Answer: D
Explanation: Desquamative gingivitis is a clinical term that often corresponds to lichen planus, mucous membrane pemphigoid, or pemphigus vulgaris.
Q: “Step-ladder” pattern of bone trabeculation is seen in
A) Scurvy
B) Thalassemia
C) Osteopetrosis
D) Rickets
✅ Correct Answer: B
