what is meant by dentiton? explained dental formula in human being
The correct spelling is dentition.
Dentition is the arrangement, type and number of teeth in the mouth of an organism.
The dental formula expresses the arrangement of teeth in each half of the upper jaw and the lower jaw. The entire formula is multiplied by two to express the total number of teeth.
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. Thus, the dental formula becomes 2102/2102 or it can also be represented as I 2/2, C 1/1, PM 0/0, M 3/3 where I = incisors, C = canine, PM = premolar, and M = molar.
The dental formula for permanent teeth in humans is: 
Each half of the upper jaw and the lower jaw has 2 incisors, 1 canine, 2 premolars, and 3 molars. An adult human has 32 permanent teeth. Thus, the dental formula becomes 2123/2123 or it can also be represented as I 2/2, C 1/1, PM 2/2, M 3/3 where I = Incisors, C = Canine, PM = premolar, and M = molar.
