Options

  1. APremolars
  2. BMolars
  3. CIncisors
  4. DCanine

Correct answer

A. Premolars

Step-by-step solution

The dental formula of human adult (permanent dentition) ICPMICPM=21232123\dfrac{ICPM}{ICPM} = \dfrac{2123}{2123}

The dental formula of the child (primary dentition) ICPMICPM=21022102\dfrac{ICPM}{ICPM} = \dfrac{2102}{2102}
