Chapter 1

Question 1

curvature of the CEJ

proximal surfaces: mesial curvature vs. distal curvature

Answer 1

generally, teeth have a greater proximal cervical line curvature on the mesial than the distal

Question 2

curvature of the CEJ

proximal surfaces: anterior teeth vs. posterior teeth

Answer 2

proximal cervical line curvatures are greatest on the mesial surfaces of central incisors and, for most teeth, tend to get smaller when moving from the anterior teeth toward the last molar where there may be no curvature at all

Question 3

curvature of the CEJ

posterior teeth: facial vs. lingual surface

Answer 3

On many posterior teeth, the cervical line is in a more occlusal position on the lingual than on the facial

Question 4

tooth with the longest crown

Answer 4

mandibular canine or maxillary central incisor

Question 5

longest tooth overall

Answer 5

maxillary canine

Question 6

longest root

Answer 6

maxillary canine

Question 7

widest crown mesiodistally

Answer 7

mandibular first molar

Question 8

widest crown buccolingually

Answer 8

maxillary first molar

Question 9

narrowest crown mesiodistally

Answer 9

mandibular central incisor

Question 10

greatest cervical line curvature

Answer 10

mesial of maxillary incisor

Question 11

facial height of contour of anterior teeth

Answer 11

cervical third

Question 12

facial height of contour of posterior teeth

Answer 12

cervical third

Question 13

lingual height of contour

Answer 13

cervical third (on cingulum)

Question 14

lingual height of contour on posterior teeth

Answer 14

in or near the middle third
