Options

A. `i//2c1//1" pm "2//2m3//3=32`
B. `i1//2c2//1" pm "2//2m3//3=32`
C. `i1//1c1//1" pm "1//2m4//4=32`
D. `i2//2c1//1" pm "3//2m2//3=32`

Answer

**Step-by-Step Text Solution:**

1. **Understanding Dental Formula**: The dental formula is a way to represent the types and numbers of teeth in one half of the mouth. In humans, there are two sets of teeth: temporary (milk teeth) and permanent (adult teeth).

2. **Identifying the Components of the Dental Formula**: The dental formula for humans is typically represented as:
- **I**: Incisors
- **C**: Canines
- **PM**: Premolars
- **M**: Molars

3. **Writing the Dental Formula**: The dental formula for adults is written as:
- **2-1-2-3** for each quadrant of the mouth. This means:
- 2 Incisors (I)
- 1 Canine (C)
- 2 Premolars (PM)
- 3 Molars (M)

4. **Calculating Total Teeth**: Since the dental formula represents one half of the mouth, we multiply the numbers by 2 to get the total number of teeth:
- Total teeth = (2 I + 1 C + 2 PM + 3 M) x 2 = (2 + 1 + 2 + 3) x 2 = 8 x 2 = 32 teeth.

5. **Verifying the Options**:
- The correct representation of the dental formula is **2-1-2-3** for both the upper and lower jaws.
- Therefore, the total count of teeth in an adult human is 32.

6. **Conclusion**: The dental formula of man is **2-1-2-3** for each quadrant, leading to a total of 32 teeth.
