1

Dental arches

Maxillary- upper teeth
Mandibular- lower teeth

2

Only bone that moves in the skull

Mandibular

3

Homodont

One form, one function

Ex: animals, shark

4

Heterodont

Several forms in the same arch with many functions

Ex: humans

5

1 Heterodont quad contains what teeth

2 incisors, 1 canine, 2 premolars, 3 molars

6

Only in permanent dentitions

Premolars (bicuspids)

7

Incisors function

Cutting

8

Canine function

Piercing

9

Premolars function

Holding and grinding

10

Molars function

Grinding

11

Polyphyodontism

Many sets of teeth
Continuous replacement of teeth

Ex: animals

12

Diphyodontism

2 sets of teeth

Ex: humans
Deciduous (primary) and permanent

13

How many teeth in Primary/deciduous? And when do they erupt?

20, 6mos-2yrs

14

How many teeth in secondary/permanent? When do they erupt?

32, 6-12yrs (except wisdom teeth)

15

Dentition

Natural teeth in the dental arch

16

Functions of primary dentitions?

Alignment, formation, speech, and mastication(eating)

17

Functions of secondary dentitions?

Esthetics(bright/white), speech and mastication(eating)

18

Secondary succedaneous

Permanent tooth that replaces a primary tooth. "Succeed"
Ex: premolars,

19

Secondary nonsuccedaneous

Permanent molars
"Nonsucceed"

20

Gingiva

Soft tissues surrounding the teeth.
Pink in color

21

Teeth components

Hard tissues.
Mastication.
4 traits- incisors, canine, premolars, molars

22

Tissues of the teeth

Enamel, dentin, cementum, and pulp

23

How mineralized is enamel?

97%

24

Dentin is..

Can it repair itself?

Bulk of tooth structure

May repair itself limitedly

25

Color of enamel is based on what 3 things?

How thick enamel is, how mineralized, color of dentin

26

Cementum

Covers dentin on ROOT surface

27

Pulp

Middle of tooth

28

Pulp consists of

Chamber, canal, and horn

29

Functions of the pulp in teeth

Vascular-supplies blood
Neurological- sensation
nourishment-

30

Anatomical crown-

The portion of the tooth covered with enamel (white area)
