Question

Dental formula of adult man is :

• A. $\frac{2123}{2123}$
• B. $\frac{2122}{2122}$
• C. $\frac{2022}{2022}$
• D. $\frac{2124}{2124}$

Answer 1

Answer: (A)

The teeth in mammals are dissimilar (heterodont). Each mammalian species is characterised by its own specific dentition with a, definite number and arrangement of teeth. The total number of teeth in a man is 32, i. e., 16 in each jaw. The dental formula of adult man is : $I\frac{2}{2}C\frac{1}{1}Pm\frac{2}{2}M\frac{3}{3}$ while dental formula of baby is $I\frac{2}{2}C\frac{1}{1}Pm\frac{O}{O}M\frac{2}{2}$ .
