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: Acellular cementum is mainly found at the
A) Coronal pulp
B) Pulp horns
C) Root apex
D) Cervical third of the root
