Answers (1)

Answer

The dental formula refers to the arrangement of teeth in each half of the upper jaw and the lower jaw. The dental formula for milk teeth in humans is:

Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, and 2 molars. Premolars are absent in milk teeth. It is represented as

2102/2102 \times 2 = 20

An adult human has 32 permanent teeth. Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, 2 premolars, and 3 molars. The dental formula for permanent teeth in humans represented as

2123/2123 \times 2 = 32
