Question

why the dental formula of human beings is 2123/2123???????,,,​

Answer 1

Answer:

because when you start counting in the front you have to incisors than the pointed one is known as canines which is one on each side and then 2 premolars and 3 molars the same ratio goes on with other side as well

Answer 2

human deciduous teeth :212/212; adult=2123/2123.

both childhood molars are replaced by adult premolars.

adult total is double the formula =32.Opossum:5134/4134( One Less incisor on each side of the lower jaw).
