Question

Dental formula in human beings is

• A. $\frac{3223}{3223}$
• B. $\frac{2123}{2123}$
• C. $\frac{1232}{1232}$
• D. $\frac{2233}{2233}$

Answer 1

The correct option is B $\frac{2123}{2123}$

An adult human has 32 permanent teeth. Humans have heterodont dentition with four different types of teeth: Incisors (I), Canines (C), Premolars (PM) and Molars (M). Arrangement of teeth in each half of the upper and lower jaw in the order I, C, PM, M is represented by a dental formula, which in humans is $\frac{2123}{2123}$.
