iii. Anatomy. The pulp is the neurovascular bundle central to each tooth, permanent or primary. It comprises a central pulp chamber, pulp horns, and radicular canals.

iv. 32 in (upper and lower) types of tooth: incisors ,canines ,premolars and molars.
functions: incisors.
Incisors are the sharp teeth at the front of the mouth that bite into food and cut it into smaller pieces. They are flat with a thin edge.
canines: Canines are the sharp, pointed teeth that sit next to the incisors and look like fangs. Dentists also call them cuspids or eyeteeth. Canines are the longest of all the teeth, and people use them to tear food.
premolars: Premolars, or bicuspids, are bigger than the incisors and canines. They have many ridges and help chew and grind up food. Adults have eight premolars. The first and second premolars are the molars that sit next to the canines.
molars: Molars are the biggest of all the teeth. They have a large, flat surface with ridges that allow them to chew food and grind it up. Adults have 12 permanent molars — six on the bottom and top jaw, and children have eight primary molars.
