                    Which one of the following correctly represents the normal adult human dental formula?

    A) \[\frac{3}{3},\frac{1}{1},\frac{3}{2},\frac{1}{1}\]                

    B) \[\frac{2}{2},\frac{1}{1},\frac{3}{2},\frac{3}{3}\]

    C) \[\frac{2}{2},\frac{1}{1},\frac{2}{2},\frac{3}{3}\]                

    D) \[\frac{3}{3},\frac{1}{1},\frac{3}{3},\frac{3}{3}\]

    Correct Answer: C

    Solution :

    The number of each type of tooth varies from one species to another and the convetional way of describing them is by a 'dental formula'. The type of teeth are indicated by the first letter, and the number of teeth on one side of upper jaw is indicated over the number of same type of teeth on the lower jaw. Because the formula is for one side of the mouth, the total number of teeth is the total in the formula \[\times 2.\] The dental formula for human adult is as follows: \[I-2/2,C-1/1,Pm-2/2,M-3/3=16\times 2=32\]where, I = Incisors, C = Canines, Pm = Premolar and M = Molars.
