A

Maxillary Lateral Incisor

6
Q

The incisal ridge of Maxillary Central Incisors is found in which position?

A

Centered labiolingually

7
Q

The incisal ridge of Maxillary Lateral Incisors is found in which position?

A

Centered labiolingually

8
Q

Which tooth is said to have a bilateral symmetric crown?

A

Mandibular Central Incisor

9
Q

Describe the position of the crown of the Mandibular Lateral incisor

A

Crown is “twisted” on root

10
Q

Which tooth has the most cervically located contact area of any incisor?

A

Maxillary Lateral incisor

centered distal contact area

11
Q

T or F, Proximal contact areas in Mandibular Central Incisors are found at the same level –> Junction of Incisal 1/3 and Middle 1/3

A

False, they are found at the same level but at INCISAL 1/3

12

A

Mandibular Central Incisors

13
Q

A

Maxillary Lateral Incisor

M-D (6.5 mm) & F-L (6.0 mm)

14
Q

What are the 3 unique characteristics that the mandibular central incisor shares with mandibular lateral incisor

A

a) fewest facial developmental depressions, lines & grooves
b) smoothest lingual surface contours
c) least developed cingulum

15
Q

Describe the position of the incisal edge in Mandibular Central incisors

A

Incisal edge is lingual to faciolingual bisector (shared with all mandibular anterior teeth)

16
Q

T or F, From the medial view in a mandibular lateral incisor, one can see the lingual portion of DMR

A

True

17
Q

Describe the incisal edge of Mandibular lateral incisors as it moves from mesial to distal

A

Distal, incisal ridge curves lingually

18
Q

Describe the MI and DI line angles in Mandibular lateral incisors

A

MI line angle sharp

DI less so
