Monophyodont teeth are -

Options

A. Incisors and Canines
B. Canines and Premolars
C. Premolars and Molar
D. Canines and Molars

Answer

**Step-by-Step Solution:**

1. **Understanding Monophyodont Teeth**:
- Monophyodont teeth are defined as teeth that are replaced only once in a lifetime. This means that individuals with monophyodont teeth will have only one set of permanent teeth after their primary teeth.

2. **Identifying Types of Teeth**:
- In humans, the types of teeth include incisors, canines, premolars, and molars. Each of these types plays a specific role in the process of chewing and digestion.

3. **Characteristics of Monophyodont Teeth**:
- Monophyodont teeth are typically characterized by the absence of certain teeth in the primary (milk) set. In humans, the premolars and the third molars (wisdom teeth) are not present in the primary set of teeth.

4. **Analyzing the Options**:
- The options given are:
- Incisors and canines
- Canines and premolars
- Premolars and molars
- Canines and molars
- We need to determine which of these combinations represents monophyodont teeth.

5. **Elimination of Incorrect Options**:
- Incisors and canines are present in the primary set, so they cannot be monophyodont.
- Canines and premolars are also present in the primary set, so this combination is not monophyodont.
- Canines and molars include canines, which are present in the primary set, thus this option is also incorrect.

6. **Identifying the Correct Answer**:
- The only combination left is premolars and molars. Since premolars are not present in the primary set and the third molar is also absent in the primary set, this combination qualifies as monophyodont teeth.

7. **Conclusion**:
- Therefore, the correct answer is that monophyodont teeth are the **premolars and molars**.
