root

22
Q

shape of the mandibular central incisor from the lingual view

A

trapezoidal in outline

smooth and rounded, slightly concave bu no distinct lingual fossa

23
Q

from the lingual view, the mesas and distal marginal ridges are only minor —

A

elevations

24
Q

the cingulum is much less distinct than the

A

maxillary incisors

25
Q

there are no — — from the lingual view

A

developmental grooves

26
Q

central incisor shape form the mesial view

A

triangular in outline

27
Q

from the mesial view, the labial outline is

A

curved (convex)

28
Q

the height of contour of the labial surface is in the

A

cervical 1/3

29
Q

the incisal edge lies —to line bisecting the root

A

lingual

30
Q

when worn, the incisal edge angles to the

A

facial

31
Q

CEJ curves incisally about 1 mm more than on the

A

distal

32
Q

cervical line extends ~1 mm more apically on the

A

lingual than the labial

33
Q

Central Incisor: Mesial View: central incisors are broader

A

labiolingually than mesiodistally

34
Q

Central Incisor: Mesial View: crown may have a concavity below the middle 1/3 above the

A

cervical line

35
Q

Central Incisor: Mesial View: root extends straight from the CEJ and tapers

A

apically from the middle 1/3

36
Q

Central Incisor: Mesial View: root may have a broad developmental depression along

A

its length

37
Q

Central Incisor: Distal View: differences from mesial view (2)

A

cervical lines curve incisally 1 mm less than on mesial

developmental depression on distal of root is greater than on the mesial

38
Q

Central Incisor: Incisal View: symmetry of the tooth is obvious

A

mesial 1/2 and distal 1/2 of the tooth are almost identical

39

Central Incisor: Incisal View: incisal edge is at right angles to a line directing the crown

A

labiolingually

incisal edge lies lingual to center of the tooth

40
Q

Central Incisor: Incisal View: tooth converges

A

lingually

the MD width of the labial surface is wider than the MD width of the lingual surface

A

faciolingually
