Question

Which one of the following correctly represents the normal adult human dental formula?

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

Answer 1

The correct option is C $\frac{2}{2},\frac{1}{1},\frac{2}{2},\frac{3}{3}$

Mammals are heterodont, meaning there are different shapes or types of teeth, denoted as I, C, P, and M (incisors, canines, premolars, and molars). The permanent or adult dental formula of humans is I 2/2, C 1/1, P 2/2, M 3/3 (x^2= 32). This is the notation format for dental formulas in mammalogy.
