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
