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: Hertwig’s epithelial root sheath helps in
A) Tooth eruption
B) Root development
C) Enamel formation
D) Crown elongation
✅ Correct Answer: B
Explanation: The epithelial root sheath guides root development by influencing the differentiation of root odontoblasts.
Q: Tomes’ process is associated with
A) Cementoblasts
B) Ameloblasts
C) Osteocytes
D) Odontoblasts
✅ Correct Answer: B
Explanation: Tomes’ process is a secretory extension of ameloblasts involved in enamel rod formation.
Q: Interglobular dentin is seen in areas where
A) Dentin is fully mineralized
B) Pulpal inflammation occurs
C) Calcification is incomplete
D) Enamel rods are absent
✅ Correct Answer: C
Explanation: Interglobular dentin results from defective or incomplete mineralization of dentin.
Q: The dental lamina gives rise to
A) Tooth germs
B) Pulp horns
C) Alveolar bone
D) Periodontal ligament
✅ Correct Answer: A
Explanation: The dental lamina is a band of epithelial tissue that initiates the formation of tooth buds.
Q: Enamel spindles are formed due to the entrapment of
A) Ameloblasts
B) Odontoblast processes
C) Fibroblasts
D) Osteoclasts
✅ Correct Answer: B
Explanation: Enamel spindles are formed by the entrapment of odontoblast processes that extend into the enamel.
