1

dentitions provide 5 basic functions: what are they

prehension
protection
esthetics
speech/communication
mastication

2

with universal system permanent dentition, what is maxillary canines

6 and 11

3

with universal system permanent dentition, what is mandibular canines

22 and 27

4

start and end at for dentition

start at maxillary right molar; end at mandibular right molar

5

maxillary central incisors permanent universal dentition

8 and 9

6

mandibular central incisors permanent universal dentition

24 and 25

7

universal primary dentition, start and end with

start with max right 2nd molar; end with mandibular right 2nd molar; only 2 molars and no premolars

8

maxillary central incisors for primary dentition

e and f

9

mandibular central incisors for primary dentition

p and o

10

maxillary canines for primary dentition

c and h

11

mandibular canines for primary dentition

m and r

12

palmar notation permanent dentition numbering

1-8 beginning with central incisors in each quadrant

13

palmar notation primary dentition numbering

a-e beginning with central incisors in each quadrant

14

palmar notation canines

3

15

palmar notation maxillary

number above the line

16

palmar notation mandibular

number below the line

17

forms outer surface of anatomical crown; most densely mineralized tissue in body; smooth and self-cleaning

enamel

18

bonelike substance that covers the root; provides medium for attachment of tooth to bone; yellow; thinnest at cervical line, thickest at apex; not as hard as enamel, similar to bone

cementum

19

where roots separate

furcation

20

forms body of tooth; less hard than enamel but harder than cementum and bone; can take forces and pressure; has some give to it

dentin

21

type of dentin-- before completion of apical foramen(embryo)

primary dentin

22

type of dentin-- after apical foramen complete(root of tooth) throughout life

secondary dentin

23

type of dentin-- stimulated to produce when trauma or injury of tooth

reparative dentin; tertiary dentin

24

housed in the center of tooth, surrounded by dentin; nourishment, sensory, formative, denfensive

pulp

25

has blood vessels, lymph vessels, connective tissue, nervous tissue, odontoblasts

pulp composition

26

part of tooth visible in mouth, sticking out of gingiva; all of it up to gingiva

clinical crown

27

the part of tooth you cannot see because it is under gingiva

clinical root

28

cementoenamel junction also called

cervical line

29

how many surfaces does a tooth have

anterior- 5 and posterior-5

30

what are the surfaces closest to the tongue

lingual

31

what are the surfaces that touch the cheeks and lips called

facial/buccal/labial

32

the mesial surfaces or 8 and 9 touch each other true or falso

true

33

what are occlusal surfaces used for

biting/chewing

34

what is a proximal surface

next to each other( distal and mesial of tooth touch)

35

formed by the junction of 2 surfaces(corner where facial and mesial of 8 meet) ex distolabial, mesiolingual

line angle

36

junction of 3 crown surfaces(molar)

point angle

37

each tooth has how many point angles

4

38

what is the lingual lobe on anterior teeth called

cingulum

39

anterior teeth form from how many lobes

4 lobes(three facial and one lingual)

40

premolars form from how many lobes

3 facial lobes and one lobe per lingual cusp

41

molars form from how many lobes

one lobe per major cusp

42

lingual lobe of an anterior tooth and makes up the bulk of the cervical third of the lingual surface

cingulum

43

rounded borders of that form the mesial and distal shoulders of the lingual surface of anterior teeth and the occlusal surface of posterior teeth

marginal ridge

44

cervical ridge on anterior teeth

facial side

45

cervical ridge on posterior teeth

buccal and lingual cervical ridges

46

ridge of each cusp that runs from the tip of the cusp to the central part of the occlusal surface

triangular ridge- on all teeth!!

47

the union of two triangular ridges; buccal and lingual ridges cross the occlussal surface of a posterior tooth (buccal to lingual)

transverse ridge; not every tooth has them

48

the only tooth on which this ridge is found is on the maxillary molar

oblique ridge

49

consists of an elevated prominence on the occlussal surface and extends obliquley from the tips of the mesiolingual cusp to the distobuccal cusp

oblique-- diagonally

50

the distinctive height of curvature seen in the cervical third of the buccal surface of a posterior tooth; mufin top of tooth; close to CEJ; height of contore

cervical ridge

51

the distictive height of curvature seen in the middle third of the facial surface of the crown on an anterior tooth. it runs cervicoincisally; cervical line to incisal edge(middle lobe; sticks out more)

labial ridge

52

fissure between the cusps on the crown of the tooth; junction forms this

developmental groove; where lobes come together

53

a minor, auxillary groove that branches off from a much more prominent developmental groove; they do not represent the junction of primary tooth parts and gives the occlusal surface a wrinkled appearance

supplemental groove

54

a rounded or angular depression of varying size found of the surface of a tooth

fossa

55

centrally located depression found on the occlusal surface of molars and mandibular second premolars. the other premolars have mesial and distal triangular fossa, but do not have this

central fossa

56

irregular, shallow depression found on the lingual surface of an incisor or canine

lingual fossa

57

located adjacent to the marginal ridges on the occlusal surfaces of posterior teeth. two types are the mesial and distal

triangular fossa

58

a depression; carved out section/area

concavity

59

an elevation; buldiing section/area

convexity
