Answer 2

Assuming the child will not have molars, which are 6 in number on each jaw, and 3 on one side of each jaw. That reduces the total number of teeth in the child from 32(which would be the number when he grows up to become an adult), to 20. The 5-yr-old would have 2 incisors, 1 canine, and 2 premolars and 0 molars on each side of each jaw.

Dental formula is based on the count of teeth on one side of the jaw to the same, for the other side of the jaw. The numerator and denominator in this formula is multiplied by 2 and numerator is added to denominator to get the total number of teeth.

Now dental formula of an individual is written in the form [math] \frac{ICPM}{ICPM}[/math], where incisors(I), canines(C), premolars(P) and molars(M) are the different types of teeth in the dentition. Following the convention, the dental formula for the child will be.
