Question

Man bears $4$ kinds of teeth from front to the back of the jaw. Choose the correct order from the following.

• A. (i)- Incisor, (ii)- Canine, (iii)- Premolars, (iv)- Molars
• B. (i)- Molars, (ii)- Canine, (iii)- Premolars, (iv)- Incisor
• C. (i)- Molars, (ii-) Canine, (iii)- Incisor, (iv)- Premolars
• D. (i)- Incisor, (ii)- Premolars, (iii)- Molars, (iv)- Incisor

Answer 1

The correct option is A (i)- Incisor, (ii)- Canine, (iii)- Premolars, (iv)- Molars

• Incisors are the most anterior teeth.
• Canines - all mammals have a single canine in each quadrant.
• The premolars lie immediately posterior to the canines.
• In the upper jaw, they are found in the maxillary.
• The most posterior teeth in the jaws of most mammals are molars.
• Humans have two incisors, one canine, two premolars, and three molars, I2 C1 P2 M3, in each quadrant of their upper jaws.
• The numbers for each quadrant of the lower jaw are the same, and the general formula is written I2/2 C1/1 P2/2 M3/3.

So, the correct answer is option A.
