Question

What will be the dental formula of a three years old child?

Answer 1

The dental formula of a three-year-old child will be: 

I \(\frac{2}{2}\), C \(\frac{1}{1}\), M \(\frac{2}{2}\) = \(\frac{2,1,2}{2,2,1}\)

i. e. 5 × 2 = 10 teeth in each jaw = 20 teeth. 

As a child has 20 teeth by the age of three.
