Solution :-
The dental formula represents the arrangement of teeth in each half of the upper jaw and the lower jaw. The entire formula is multiplied by two to give the total number of teeth present in different stages of life. In human beings the dental formula for milk teeth is:
Here each half of the upper jaw and lower jaw has 2 incisors, 1 canine, and 2 molars. In milk teeth the premolars are absent.
In humans the dental formula for permanent teeth is: Here each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, 2 premolars, and 3 molars. The total number of permanent teeth present in an adult human is 32.
