Question

Bulk of the tooth in mammals is made up of:

• A. Dentine
• B. Enamel
• C. Pulp cavity
• D. Root

Answer 1

The correct option is A Dentine

Dentine is a calcified tissue of the body, and along with enamel, cementum, and pulp is one of the four major components of teeth. It is usually covered by enamel on the crown and cementum on the root and surrounds the entire pulp.

By weight, 70% of dentin consists of the mineral hydroxyapatite, 20% is organic material, and 10% is water. Yellow in appearance, it greatly affects the color of a tooth due to the translucency of enamel.

Dentine, which is less mineralized and less brittle than enamel, is necessary for the support of enamel.

So, the correct answer is option A- 'Dentine'.
