Question

Which of the following is not found in the root?

• A. Enamel
• B. Dentin
• C. Cementum
• D. Pulp

Hint:

Enamel is only found on the crown of the tooth, while the root is covered by cementum and contains dentin and pulp.

Answer 1

The Correct Option is A

To determine which of the given options is not found in the root of a tooth, we need to understand the basic anatomy of a tooth. A tooth is composed of several parts:

• Enamel: This is the hard, outermost layer of a tooth. Enamel covers the crown of the tooth and is not found in the root.
• Dentin: This is the layer found beneath the enamel in the crown and it also extends down to the root, where it’s covered by cementum.
• Cementum: This is a bone-like substance that covers the tooth's root and helps anchor it into the bone socket via the periodontal ligament.
• Pulp: This is the innermost part of the tooth containing nerves and blood vessels. It extends into the root of the tooth through the root canals.

Based on this information, the part that is not found in the root is Enamel. Enamel is exclusively part of the tooth's crown and does not extend to the root. The other options—dentin, cementum, and pulp—are all parts that are present in the root of the tooth.

Therefore, the correct answer is:

• Enamel
