1

what is the primary function of incisors?

biting

2

which permanent tooth has the greatest FL axial inclination?

maxillary central incisors

3

which permanent tooth has the greatest cervical curvature of any other tooth?

-maxillary central
-curvature is on the mesial

4

what are the 3 rules associated with cervical curvatures?

dips deeper on...
-anterior teeth than posterior teeth
-maxillary than mandibular
-mesial than distal

5

which teeth are the only anterior teeth that are wider MD than FL?

maxillary central incisors

6

which tooth has the greatest MD crown dimension of any other anterior tooth?

maxillary central incisors

7

which two measurements of maxillary central incisors are nearly identical?

incisocervical and mesiodistal

8

the contact between a maxillary central and a lateral incisor makes the lingual embrasure _(smaller/larger)_ than the facial

larger

9

the incisal embrasure between the maxillary centrals is _(smaller/larger)_ than between the central and lateral

smaller

10

which permanent tooth has the most variation in crown shape?

maxillary lateral incisors

11

the ___ exhibits the most deviation in crown morphology, followed by the ___

-3rd molars
-maxillary lateral incisor

12

which tooth is most often in abnormal relation and contact with adjacent teeth?

maxillary lateral incisor

13

the ___ is most often congenitally missing, followed by ___

-3rd molars
-maxillary lateral incisors

14

the non-molar tooth that most frequently has a M and D pulp horn is the ___

maxillary central incisor

15

the non-molar tooth that is least likely to have a bifurcated root is the ___

maxillary central incisor

16

the anterior tooth that most likely would demonstrate lingual pit caries is the ___

maxillary lateral incisor

17

what anatomical feature of maxillary lateral incisors complicates root planing?

DL groove

18

the distoincisal angle of which teeth has the greatest convexity of all maxillary anterior teeth?

maxillary lateral incisor

19

which teeth generally have the most prominent marginal ridges of all anterior teeth?

maxillary lateral incisors

20

which teeth have the most distinct and deepest lingual fossas of all anterior teeth?

maxillary lateral incisors

21

which tooth has the smallest MD crown width of any maxillary tooth?

maxillary lateral incisor

22

which maxillary tooth has a MD measurement that is nearly identical to its FL measurement?

maxillary lateral incisor

23

the MD width of the maxillary lateral incisor is _(wider/narrower)_ than the maxillary central incisor

narrower

24

which incisor has a distal contact that is the farthest cervical of any incisor?

maxillary lateral

25

the maxillary lateral distal contact is located where?

centered both inciso-cervically and facio-lingually

26

the maxillary lateral incisor is usually equal to or larger than the ___ in root length

maxillary central incisor

27

how are mandibular central incisors distinguished from each other?

their cervical curvature, which is greater on the M than the D

28

mandibular central and laterals most frequently have concave areas on which root surface?

M and D

29

which tooth has the smallest crown dimensions of any tooth?

mandibular central incisors

30

which tooth has the most symmetrical crown?

mandibular central incisor
