Is dentine sensitive to pain?

What does pulp contain?

What is the pulp chamber?

What supporting structures can you name?

Exercise8. Decide whether the following statements are true or false.

Enamel is very sensitive to pain.

Gingiva holds the root in the socket in the jaw.

A small, calcified, whitish structure found in the jaws and used to break down food is known as crown.

Odontoblast is a part of the outer surface of the dental pulp beneath the tooth enamel on the crown and the cementum on the root.

Blood vessels and nerves enter the root apex through the apical foramen.

The lower teeth set in a movable foundation called mandible.

Enamel is white but transparent.

The tooth sockets are covered with hard ivory tissue called the gum.

Exercise 10. Match the words with their definitions.

1. tooth

2. roots

3. enamel

4. cementum

5. dentin

7. crown

8. alveolar process

a) It is a thin layer of bonelike material covering the root of a tooth.

b) A part of the tooth above the gums.

c) It is a yellowish tissue that makes up the bulk of all teeth. It is harder than bone but softer than enamel. Sensitivity to pain, pressure, and temperature is transmitted through it.

d) It makes up a visible part of the tooth, covering the crown.It is the hardest substance in the human body.

e) It is the thickened ridge of bone that contains the tooth sockets on bones that hold teeth.

f) They are normally buried in the jaw, and they serve to anchor the tooth in position.

g) It is the part in the center of a tooth made up of living connective tissue and cells called odontoblasts.

h) Each of a set of hard, bony enamel-coated structures in the jaws of most vertebrates, used for biting and chewing.

Exercise 11. Translate the phrases given in italics into English.

Чутливість до болю increases when the tooth is drilled.

Bone tissue consists of cortical bone and губчаста кістка.

The outer layer of bones is called компактна кістка and the inner layer is called cancellous bone.

The opening at the apex of the root of a tooth that gives passage to the nerve and blood vessels is called верхівковий отвіркорня зуба.

The cavity in the tooth can піддаватися відновленню by filling.

Щільний зовнішній шар of the tooth surface is formed by enamel.

The tooth is drilled to reach пульпова камера and extract the pulp.

Enamel unlike pulp, that is цілковито м’яка тканина, consists of the hardest tissue in the human body.
