Which of the following forms the major part of the tooth and is covered by enamel ?

Options

A. Enamel
B. Dentine
C. Cement
D. Odontoblast

Answer

**Step-by-Step Solution:**

1. **Understanding Tooth Structure:**
- The tooth consists of several layers, each with its own function. The main layers include enamel, dentine, cementum, and the pulp cavity.

2. **Identifying Enamel:**
- Enamel is the outermost layer of the tooth. It is known for being the hardest substance in the human body and serves to protect the underlying layers from wear and tear.

3. **Identifying Dentine:**
- Beneath the enamel lies dentine, which forms the major part of the tooth. Dentine is softer than enamel but provides structural support to the tooth.

4. **Relationship Between Enamel and Dentine:**
- Enamel covers the dentine. This means that while enamel is the outer protective layer, dentine is the main bulk of the tooth structure beneath it.

5. **Conclusion:**
- The question asks for the major part of the tooth that is covered by enamel. Since dentine is the layer that lies beneath enamel and constitutes the majority of the tooth's structure, the answer is dentine.

**Final Answer:**
- Dentine forms the major part of the tooth and is covered by enamel.
