order of standardized tooth identification
set arch side type class
38
example of standardized tooth id
permanent mandibular left second molar
39
if permanent, blank does not have to be stated
set
40
allows for ease of documentation of dental records. like shorthand, rather than completely writing everything out
numbering systems
41
three types of numbering systems
universal (KNOW),
| palmer, fdi, (know only how they work)
42
universal numbering system is for blank teeth
permanent
43
universal numbering system starts where
maxillary right 3rd molar
44
universal numbering system ends at blank
mandibular right
45
this numbering system uses four brackets to denote each quadrant
palmer system
46
an attempt at a worldwide standardization used in Europe and canada
fdi
47
fdi stands for
federation dentaire internationale
48
fdi uses a blank where first number identifies blank and second number identifies blank
binomial, quadrant (1-4 permanent, 5-8 deciduous), tooth (1-8 permanent starting at central incisor, 1-5 deciduous)
49
two separate sets of teeth or dentitions
diphyodont
50
anterior teeth include these
to canine
51
anterior teeth have blank surfaces and blank edges
4, 1
52
midline surface of anterior teeth

53
away from midline surface of anterior teeth
distal
54
surface of anterior teeth toward lips
labial (facial)
55
surface of anterior teeth toward the palate
palatal (lingual)
56
biting edge of anterior teeth
incisal
57
posterior teeth have blank surfaces
five
58
posterior teeth next to the cheeks
buccal (facial)
59
posterior teeth surface toward tongue
lingual or palatal (maxillary)
60
chewing surface of posterior teeth
occlusal
61
line formed by the junction of two crown surfaces
line angle
62
blank line angles to each tooth... ex) mesiolabial, distolingual, mesio-occlusal
8
63
junction of three crown surfaces and takes name of the three surfaces
point angles
64
the crown is divided into artificial blank both horizontally and vertically
thirds
65
horizontal thirds
incisal/occlusal, middle, cervical/gingival
66
vertical thirds
distal, middle, mesial
67
area of greatest convexity on the facial and lingual surfaces
height of contour
68
height of contour is the blank part of the tooth
fattest
69
height of contour diverts food from packing into blank
gingiva
70
where one tooth touches the other
contact area
71
when adjacent teeth touch, the space that surrounds the contact area can be divided into separate triangular blank spaces
embrasure
72
two embrasure spaces
occlusal, gingival
73
two embrasure spaces looking inferiorly
buccal, lingual
74
all normal teeth develop from three or more blank
lobes
75
incisors develop from blank lobes
4
76
