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 stellate reticulum is part of the
A) Enamel organ
B) Pulp core
C) Dental follicle
D) Periodontal ligament
โœ… Correct Answer: A

Q: The first formed dentin is known as
A) Secondary dentin

C) Reparative dentin
D) Tertiary dentin
โœ… Correct Answer: B
Explanation: Primary dentin is deposited during tooth development before root completion and forms the bulk of the tooth.
Q: The reduced enamel epithelium helps in
A) Cementum formation
B) Root canal therapy
C) Enamel mineralization
D) Eruption of teeth
โœ… Correct Answer: D
Explanation: The reduced enamel epithelium protects the enamel and contributes to eruption by fusing with oral epithelium.
Q: Resting lines in cementum represent
A) Caries progression
B) Epithelial cell division
C) Periods of rest in cementum formation
D) Continuous deposition
โœ… Correct Answer: C
Explanation: Resting lines in cementum are incremental growth lines indicating pauses in cementum deposition.
Q: The dental papilla gives rise to
A) Periodontal ligament
B) Enamel organ
C) Cementum
