Week 2

Question 1

Anatomical crown

Answer 1

Portion of tooth covered by enamel

Question 2

Clinical crown

Answer 2

Portion of tooth visible by mouth

Question 3

What are 3 types of macro anatomy

Answer 3

. Roots cervical line and crown

Question 4

In adult stage what or proportion between anatomical and clinal crown

Answer 4

Equal - best condition

Question 5

In young stage what it the proportion between anatomical = and clinical crown

Answer 5

At Th teeth hasn’t fully erupted, Joy would expect more artaomical

Question 6

In old stage what it the proportion between anatomical = and clinical crown

Answer 6

Due to gum recession you would expect Th clinical crown to be shown more

Question 7

What it atomical root

Answer 7

Part of the root covered by cementum

Question 8

What is the cervical line / cement enamol junction

Answer 8

A line that separates anatomical root from anatomical crown

Question 9

What are the 3 micro-anatomy of the teeth

Answer 9

Enamel, dentin, cementum

Question 10

What it enamel

Answer 10

Hard, mineralized tissue hardest living tissue
Ectodermal in origin
Covers anatomica crown

Question 11

Dentin?

Answer 11

Hard tissue which former main body of tooth, surround pulp cavity, and is covered enamel. Less minimized than caramel, it does not fracture, resident material so it protect enamel. Less hard than enamel . But harder than cementum

Question 12

Cementum 7

Answer 12

Hard bone like tissue which cover dentin of anatomical root.

Question 13

What is dentino-enamel junction, Dej

Answer 13

Internal line separating dentin and enamel in anatomical crown

Question 14

What it dentino-cementum junction or dcj

Answer 14

Internal line of metry dentin and cementum in anatomical root

Question 15

What is pulp

Answer 15

Living sot tissue; tooth blood vessel and nerve supply. Also called dental pulp

Question 16

What it pulp cavity

Answer 16

Entire internal cavity of tooth that has these entities: pulp canal, pulp chamber, pulp horn and the apical foreman

Question 17

Pulp cavity / root canal?

Answer 17

portion of pulp cavity which is located in root of the tooth (also called as root canal)

Question 18

Pulp chamber-

Answer 18

enlarged portion of pulp cavity which is found mostly in anatomical crown

Question 19

Pulp horns-

Answer 19

usually pointed incisal or occlusal elongations of pulp chamber which often correspond to cusps, or lobes of teeth

Question 20

Apical foramen-

Answer 20

the end of the pulp canal by which pulp tissues connect to the periodontal tissues.

Question 21

Alveolar process

Answer 21

bone which surrounds & supports
all teeth in each jaw.

Question 22

bony socket,-• portion of alveolar process, into which an erupted tooth is set.

Answer 22

bony socket,-• portion of alveolar process, into which an erupted tooth is set.

Question 23

Crypt

Answer 23

portion of the alveolar process into which an unerupted tooth is set.

Question 24

Periodontal ligament (membrane)

Answer 24

fibrous attachment of tooth cementum to the alveolar bone

Question 25

Gingiva or “gums“-

Answer 25

Fibrous tissue enclosed by mucous membrane that covers alveolar processes & surrounds necks of teeth.

Question 26

Periodontium apparatus-

Answer 26

is a system which responsible for holding a tooth in its bony socket. Composed of
a- Periodontal ligaments
b- Alveolar bone
c- Cementum and;
d- Gingiva
