Explanation

Dental formula is a representation of the dntition of an animal. A dental formula consists of eight numbers, four above and four below a horizontal line. The numbers represent (from left to right) the number of incisors, canines, premolars and molars in either half of the upeer and lower jaws e.e., the dental formula of man is `(2123)/(2123)`
Dental formula is used to represent heterodont teeth which are present in mammals only. It cannot be used to represetn dentition of vartebrates other than mammals as they have homodont teeth.
