Mand. Incisors

Question 1

The height of contour on the Mand. central incisor is located at ……..

Answer 1

the incisal edge (on both mesial and distal)

Question 2

The most symmetric of all teeth is ….

Answer 2

the Mand. central incisor

Question 3

The lingual surface of the Mand. incisors has ……. anatomy

Answer 3

an indistinct

Question 4

On the Mand. central incisor, the incisal edge is ……. to a line bisecting the tooth labiolingually

Answer 4

perpendicular

Question 5

On root cross section, the Mand. central incisor is …….

Answer 5

ovoid & wider labiolingually than mesiodistally

Question 6

The Mand. lateral incisor is ……. mesiodistally than the central

Answer 6

wider

Question 7

The Mand. lateral incisor is symmetric. T/F??

Answer 7

False

Unlike the central, the lateral is asymmetric

Question 8

The mesial height of contour for the Mand. lateral incisor is at ……, while the distal is …..

Answer 8

the incisal edge
* the distal is height of contour is at the incisal third. The distal surface is convex (unlike the mesial) and with rounded distoincisal angle

Question 9

The Mand. lateral incisor incisal edge is ……… to the line bisecting the crown labiolingually

Answer 9

not perpendicular

* The distal edge is rotated to the lingual

Question 10

The cross section of the Mand. lateral incisor root is …….

Answer 10

very ovoid (wider labiolingually than mesiodistally)
* The root may have mesial and distal depression
