t/f: maxillary central incisors are largest permanent incisors
true
44
t/f: permanent mandibular central incisors are smallest permanent teeth
true
45
t/f: mandibular incisors erupt with their incisal edges already worn in
false
46
t/f: permanent maxillary centrals vary more in form than any other maxillary teeth
false | laterals do
47
t/f: maxillary incisors have their contact areas located more incisally than mandibular incisors
false
48
t/f: because of their longer roots, maxillary laterals have a greater crown to rooth ratio than maxillary centrals
false | lesser crown to root ratio
49
t/f: maxillary centrals and laterals are wider faciolingually than mesiodistally
false; mandibular incisors are
50
t/f: maxillary incisors have their incisal edges toward the lingual surface
true
51
t/f: of the mandibular incisors, the lateral has largest crown and largest root
true
52
characteristics found exclusively on incisors
true incisal ridges | mamelons
53
convexity that runs from linguocervical third of anterior teeth onto lingual fossa is the
cingulum
54
because they are more likely to have lingual pit, what tooth hs more lingual cavities
maxillary laterals
55
only anterior teeth wider mesiodistally than faciolingually
maxillary incisors
56
most distinguishing feature of mandibular lateral incisor
distal rotation of crown over the root
57
tooth most likely to have a proximal groove in root
mandibular lateral
58
incisor most likely to vary in number of pulp horns
maxillary lateral
59
incisors tipped lingually in a class II divisionII orthodontic malocclusion
maxillary centrals and sometimes maxillary lateral incisors as well as mandibular incisors
60
incisors have only one antagonist
mandibular centrals
