Pulp

Question 1

What is it?

Answer 1

contains no mineral crystals + is composed of purely soft tissue. it lies within centre of every tooth, from crown as the coronal pulp + into each root as the radicular pulp (root Canal).
its properties + microscopic structures:

Question 2

1.

Answer 2

contains sensory nerves + blood vessels. the sensory nerves are end sections of trigeminal nerve (5th cranial nerve), either as the inferior dental nerve for lower or one of the superior dental nerves for upper

Question 3

2.

Answer 3

they allow tooth to feel hot, cold, touch + pain by stimulation of its sensory nerve ending which run as fibrils in the hollow dentine tubules

Question 4

3.

Answer 4

these pulp tissues enter the tooth through the apical foramen, lying at the root apex of every tooth

Question 5

4.

Answer 5

lined with odontoblast cells which from dentine
the chamber gradually narrows with age, so that is can become completely obliterated with older pts, making endodontics difficult

Question 6

5.

Answer 6

can become blocked by pulp stones which are formed by lumps of calcium-containing crystals

Question 7

6.

Answer 7

the point where the cementum + root dentine are in contact with each other is called the dentinocemental junction

Question 8

7.

Answer 8

some teeth have additional contact between the pulp + surrounding periodontal ligament via accessory canals, whose presence can make successful endodontics very difficult to achieve
