Question:

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

33,11,32,11

22,11,22,33

22,11,32,33

33,11,33,33

Solution:

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.
