Surface anatomy ( all aspects ) of maxillary lateral incisor

Question 1

Labial surface

Answer 1

Is more convex then central

Question 2

Labial developmental grooves

Answer 2

Are less prominente then central

Question 3

Crown surface anatomy

Answer 3

The crown is 2mm narrower then that of the central incisor

Question 4

Root surface anatomy of maxillary lateral incisor

Answer 4

• tapers towards the pointed apex
• its apical end is curved distally
• the root is narrow mesiodistally then central incisor
• the root is longer / same length then the central
• the root is about one and half times the length of the crown

Question 5

Lingual surface anatomy of maxillary lateral incisor

Answer 5

• marginal ridges are prominent
• the cingulum and incisal ridge are well developed
• the lingual fossa is more concave
• the palatal pit is enclosed by the cingulum

Question 6

Mesial surface anatomy of maxillary lateral incisor

Answer 6

Similar to central incisor except

• labiolingual measurements of the crown is smaller
• its incisal portion is somewhat thicker
• the curvator of the cervical line is well marked
• the root apears longer but narrower then the central

Question 7

Distal surface anatomy of maxillary lateral incisor

Answer 7

• this is thicker then mesially
• the curvator of the cervical line is less in depth
• the distal surface of the root is slightly more convex then mesial surface
