Oral Histology MCQs
Oral Histology MCQs are tailored for dentistry students seeking mastery of tooth development and oral tissue structure. These questions focus on enamel formation, dentin-pulp complex, cementum, alveolar bone, and salivary glands. They're excellent for preparation of BDS, MDCAT, and related tests.
Q: The enamel cuticle secreted by ameloblasts is known as
A) Secondary cuticle
B) Acquired pellicle
C) Reduced enamel epithelium
D) Primary cuticle
✅ Correct Answer: D
Explanation: The primary enamel cuticle is a thin organic layer deposited by ameloblasts after enamel formation.
Q: Collagen fibers in dentin are primarily composed of
A) Type II collagen
B) Type I collagen
C) Type III collagen
D) Type IV collagen
✅ Correct Answer: B
Explanation: Type I collagen is the main structural protein in dentin, providing a framework for mineral deposition.
Q: Granular layer of Tomes appears granular due to
A) Hypocalcification
B) Enamel projections
C) Air voids
D) Cross-sectional tubules
✅ Correct Answer: D
Explanation: The granular appearance results from looping or branching of dentinal tubules near the root.
Q: The process of dentin formation is known as
A) Dentinolysis
B) Cementogenesis
C) Dentinogenesis
D) Pulpogenesis
✅ Correct Answer: C
Explanation: Dentinogenesis is the biological process by which odontoblasts produce dentin.
Q: Enamel is the hardest tissue in the human body
A) Dentin
B) Enamel
C) Cementum
D) Bone
✅ Correct Answer: B
Explanation: Enamel is composed of highly mineralized hydroxyapatite crystals, making it extremely hard.
