Question

The dental formula of human beings is

• A. $\frac{2,0,3,3}{1,0,2,3}$
• B. $\frac{2,1,2,3}{2,1,2,3}$
• C. $\frac{2,1,2,0}{2,1,2,0}$
• D. $\frac{2,1,1,1}{2,1,1,1}$

Answer 1

The correct option is B

$\frac{2,1,2,3}{2,1,2,3}$

The correct option is B:

Explanation of the correct option:

1. In mammals, the number of teeth is represented by a dental formula on the basis of their place and function. The dental formula is represented in the following way:$\frac{\mathrm{Number}\mathrm{of}\mathrm{teeth}\mathrm{in}\mathrm{each}\mathrm{half}\mathrm{of}\mathrm{upper}\mathrm{jaw}}{\mathrm{Number}\mathrm{of}\mathrm{teeth}\mathrm{in}\mathrm{each}\mathrm{half}\mathrm{of}\mathrm{lower}\mathrm{jaw}}$
2. For example,
   The dental formula of a human being is :$\frac{2,1,2,3}{2,1,2,3}$ , $\frac{\mathrm{Incisors},\mathrm{Canines},\mathrm{Premolars},\mathrm{Molars}}{\mathrm{Incisors},\mathrm{Canines},\mathrm{Premolars},\mathrm{Molars}}$
3. In humans, There are Total Incisors 8, Total Canines 4, Total Premolars 8 and Total Molars 12.

Final answer: The dental formula of human beings is$\frac{2,1,2,3}{2,1,2,3}$.
