Q

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

A

pulp

25
Q

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

A

pulp composition

26
Q

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

A

clinical crown

27
Q

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

A

clinical root

28
Q

cementoenamel junction also called

A

cervical line

29
Q

how many surfaces does a tooth have

A

anterior- 5 and posterior-5

30
Q

what are the surfaces closest to the tongue

A

lingual

31
Q

what are the surfaces that touch the cheeks and lips called

A

facial/buccal/labial

32
Q

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

A

true

33
Q

what are occlusal surfaces used for

A

biting/chewing

34
Q

what is a proximal surface

A

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

35
Q

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

A

line angle

36
Q

junction of 3 crown surfaces(molar)

A

point angle

37
Q

each tooth has how many point angles

A

4

38
Q

what is the lingual lobe on anterior teeth called

A

cingulum

39
Q

anterior teeth form from how many lobes

A

4 lobes(three facial and one lingual)

40
Q

premolars form from how many lobes

A

3 facial lobes and one lobe per lingual cusp

41
Q

molars form from how many lobes

A

one lobe per major cusp

42
Q

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

A

cingulum

43
Q

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

A

marginal ridge

44
Q

cervical ridge on anterior teeth

A

facial side

45
Q

cervical ridge on posterior teeth

A

buccal and lingual cervical ridges

46
Q

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

A

triangular ridge- on all teeth!!

47
Q

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

A

transverse ridge; not every tooth has them

48
Q

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

A

oblique ridge

49
Q

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

A

oblique– diagonally

50
Q

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

A

cervical ridge

51
Q

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)

A

labial ridge

52
Q

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

A

developmental groove; where lobes come together

53
Q

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

A

supplemental groove

54
Q

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

A

fossa

55
Q

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

A

central fossa

56
Q

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

A

lingual fossa

57
Q

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

A

triangular fossa

58
Q

a depression; carved out section/area

A

concavity

59
Q

an elevation; buldiing section/area

A

convexity
