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 tissue responsible for cushioning the tooth within the socket is the
A) Pulp
B) Periodontal ligament
C) Cementum
D) Enamel
โœ… Correct Answer: B
Explanation: The periodontal ligament acts as a shock absorber and anchors the tooth to the alveolar bone.
Q: Cap stage of tooth development is characterized by formation of the
A) Dental lamina only
B) Dentin matrix
C) Root sheath
D) Dental papilla and enamel organ
โœ… Correct Answer: D
Explanation: The cap stage marks the initial formation of the enamel organ and dental papilla, setting the groundwork for future tissues.
Q: The first mineralized structure to appear in the developing tooth is
A) Cementum
B) Enamel
C) Dentin
D) Bone
โœ… Correct Answer: C
Explanation: Dentin formation (dentinogenesis) begins before enamel, marking the start of hard tissue development.
Q: The junctional epithelium originates from
A) Stratum intermedium
B) Reduced enamel epithelium
C) Oral ectoderm
D) Dental follicle
โœ… Correct Answer: B
Explanation: Junctional epithelium, which adheres to the tooth surface, derives from the reduced enamel epithelium after eruption.
Q: The mineralization front in dentin is located between
A) Predentin and dentin
B) Cementum and enamel
C) Dentin and pulp
D) Enamel and cementum
โœ… Correct Answer: A
Explanation: The mineralization front is the boundary where unmineralized predentin becomes mineralized dentin.
