Dental formula shows

Options

A. Structure of teeth
B. Monophyodont or diphyodont condition
C. Number and type of teeth in both jaws
D. Number and type of teeth in one half of both jaws.

Answer

**Step-by-Step Solution:**

1. **Understanding Dental Formula**: The dental formula is a shorthand way of representing the number and types of teeth in one half of the mouth (one quadrant).

2. **Example of Human Dental Formula**: The dental formula for humans is represented as 2123/2123. This means:
- 2 Incisors
- 1 Canine
- 2 Premolars
- 3 Molars
This pattern is repeated for the other half of the jaw, making a total of 32 teeth in adults.

3. **Breaking Down the Components**:
- The first part (2123) represents the upper jaw (maxilla).
- The second part (2123) represents the lower jaw (mandible).

4. **Clarifying the Options**:
- **Option 1**: Structure of teeth - Incorrect, as the dental formula does not describe the structure.
- **Option 2**: Monophyodont or diphyodont - Incorrect, as the dental formula does not categorize teeth types.
- **Option 3**: Number and type of teeth in both jaws - Incorrect, as it only represents one half of each jaw.
- **Option 4**: Number and type of teeth in one half of both jaws - Correct, as it accurately describes what the dental formula represents.

5. **Conclusion**: The correct answer is that the dental formula shows the number and type of teeth in one half of both jaws.
