Question

What is the dental formula and dental arcade shape of Strepsirrhine?

Answer 1

The dental formula of strepsirrhine is 2.1.3.3.

Which means there are 2 incisors,1 canine 3 premolar and 3 molars in one side. This value multiplied by four is the total number of teeth in this primate species. It differs from humans by the increase in number of premolars. Human dental formula is 2.1.2.3

Dental archade is the arrangement of teeth in the upper jaw. Incase of strepsirrhine it has a V shaped arrangement where the incisors are followed by the canine and the premolars with the canine shape. The canine is large enough like many other primates. There is diastema between the initial incisors in the upper jaw so as to adapt the longer incisors of the lower jaw. Diastema is the gap between teeths. There is also diastema between the canine and the premolars to adapt the bigger canines in the lower jaw.
