Question

Dental formula of an adult man is ___________.

• A. $\frac{2123}{2123}$
• B. $\frac{2123}{2122}$
• C. $\frac{2123}{2124}$
• D. $\frac{2132}{2132}$

Answer 1

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

The dental formula represents the arrangement of teeth in each half of the upper and the lower jaw. The entire formula is multiplied by two to represent the total number of teeth.

The dental formula for permanent teeth in humans is: $\frac{2123}{2123}\times 2=32$.

Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, 2 premolars, and 3 molars. An adult human has 32 permanent teeth.
