Question:
The basic shape of tooth is derived from dentin, which is a ____ tissue.
The basic shape of tooth is derived from dentin, which is a ____ tissue.
Show Hint
Dentin has a collagen matrix hardened with calcium salts, like bone.
Updated On: Nov 12, 2026
- dense connective
- calcified connective
- hyaline cartilage
- adipose
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Dentin forms the bulk of the tooth beneath the enamel and surrounds the pulp cavity. It gives the tooth its basic shape.
Step 2: Composition
Its matrix is rich in collagen and hardened by deposits of calcium salts (hydroxyapatite), produced by odontoblasts.
Step 3: Conclusion
A connective tissue hardened with calcium is called a calcified connective tissue, like bone.
Final Answer:
Dentin is a calcified connective tissue. \[ \boxed{\text{(B) }\text{calcified connective}} \]
