Answer 4

distal

Question 5

Question 6

Biting surface of an anterior tooth.

Answer 6

incisal

Question 7

The surface of a posterior tooth that faces the cheeks.

Answer 7

buccal

Question 8

There are a total of 20 teeth in the primary dentition. There are no premolars in the primary dentition.
Are these statements true or false?

Answer 8

Both statements are true.

Question 9

What is the term for the junction of enamel and cementum?

Answer 9

cementoenamel junction

Question 10

Each dental arch can be divided by an imaginary line through the midline resulting in 4 parts. Each part is called a sextant. True or false?

Answer 10

The first statement is true. The second statement is false.

The arches can be divided into 4 or 6 parts. Four parts are quadrants; 6 parts are sextants.

Question 11

Mesial and distal surfaces between adjacent teeth are termed proximal. T or F?

Answer 11

True

Question 12

When dividing a tooth crown into three horizontal divisions, the division that is closest to the root is the cervical third. T or F?

Answer 12

True

Question 13

The apical 1/3 of a tooth root is closest to the crown.

T or F?

Answer 13

False

Question 14

From a facial/labial view, the outline shape of the permanent maxillary central incisor root is much like an ice cream cone. T or F?

Answer 14

True

Question 15

The permanent maxillary central incisor has a longer root than the permanent maxillary lateral incisor. T or F?

Answer 15

False

Question 16

Developmental lobes that form the facial surface of incisors also contribute to mamelons. T or F?

Answer 16

True

Question 17

In a facial/labial view, the permanent maxillary central incisor is more symmetrical than the permanent maxillary lateral incisor. T or F?

Answer 17

True

Question 18

In the permanent maxillary lateral incisor, the lingual fossa is shallow and large. T or F?

Answer 18

False

Question 19

The universal number for the permanent LEFT mandibular central incisor is

Answer 19

24

Question 20

The depression on the lingual surface of incisors is called a

Answer 20

fossa

Question 21

The permanent mandibular incisor that is the most symmetrical is the

Answer 21

central incisor

Question 22

Of the permanent mandibular incisors, the one that is largest is the

Answer 22

lateral incisor

Question 23

In permanent mandibular incisors, the proximal surface that has the deepest root depression is distal. T or F?

Answer 23

True

Question 24

For both the permanent mandibular incisors, the mesial cervical line curve is greater than the distal cervical line curve. T or F?

Answer 24

True

Question 25

Permanent mandibular incisors erupt earlier than permanent maxillary incisors. T or F?

Answer 25

True

Question 26

The cingulum of the permanent mandibular central incisor is toward the distal. T or F?

Answer 26

False

Question 27

The cingulum of the permanent mandibular lateral incisor is centered. T or F?

Answer 27

False

Question 28

What is a marginal ridge?

Answer 28

Marginal ridges are elevations of enamel that form the mesial and distal borders of a tooth. In incisors, they are seen on the lingual surface and converge toward the cingulum.
