If the dental formula of Rabbit is 2033/1023. What does it show

Options

A. Total number of teeth in rabbit is 15.
B. Number of total incisors in rabbit is 3.
C. Diastema is present between incisors and premolars
D. In the formula, 2033 is for adults and 1023 is for young ones.

Answer

To analyze the dental formula of a rabbit, which is given as 2033/1023, we can break it down step by step.

### Step-by-Step Solution:

1. **Understanding the Dental Formula**:
The dental formula is written as two numbers separated by a slash (/) that represent the teeth in the upper jaw and lower jaw respectively. In this case, 2033 refers to the upper jaw and 1023 refers to the lower jaw.

2. **Breaking Down the Numbers**:
- The first number (2) indicates the number of incisors.
- The second number (0) indicates the number of canines.
- The third number (3) indicates the number of premolars.
- The fourth number (3) indicates the number of molars.
- The same breakdown applies to the lower jaw (1023).

3. **Total Teeth Calculation**:
- For the upper jaw: 2 (incisors) + 0 (canines) + 3 (premolars) + 3 (molars) = 8 teeth.
- For the lower jaw: 1 (incisor) + 0 (canine) + 2 (premolars) + 3 (molars) = 6 teeth.
- Total teeth in a rabbit = 8 (upper) + 6 (lower) = 14 teeth.

4. **Identifying the Absence of Canines**:
The dental formula shows a '0' for canines, indicating that rabbits do not have canine teeth. This absence creates a gap between the incisors and the premolars, which is known as a diastema.

5. **Conclusion**:
The dental formula of the rabbit (2033/1023) indicates that:
- There are no canines present.
- A diastema exists between the incisors and premolars.
- The total number of teeth in a rabbit is 28 (16 in the upper jaw and 12 in the lower jaw).

### Final Answer:
The correct interpretation of the dental formula 2033/1023 for a rabbit is that it shows the presence of a diastema between the incisors and premolars, and the absence of canines.
