Question 1

What does cementum cover?

Answer 1

Surface of the root of the tooth

Question 2

What does cementum do?

Answer 2

Provides a medium for the attachment of periodontal ligaments

Question 3

What is the alveolar process?

Answer 3

The extension of bone from the body of the mandible and the maxilla

Question 4

What does the alveolar process do?

Answer 4

Support the teeth in their functional positions in the jaw

Question 5

Relationship between alveolar process and developing teeth?

Answer 5

The stimulus for the production of the alveolar process is the developing teeth

Question 6

Central portion of alveolar process?

Answer 6

Made of spongy bone

Question 7

Alveolar socket

Answer 7

(alveolus)

the cavity within the alveolar process in which the root of the tooth is held

Question 8

Interdental septum

Answer 8

Bony projection that separates one socket from another

Question 9

Interradicular septum

Answer 9

Bone that separates the roots of a multi-rooted tooth

Question 10

What is alveolar bone?

Answer 10

The bone of the maxillary and mandibular jaw that makes up the sockts for the teeth

Question 11

Composition of alveolar bone?

Answer 11

65% inorganic crystal and 35% organic, collagen, and non-collagenous fibers

Question 12

3 layers of alveolar bone

Answer 12

1. cortical plate
2. cribiform plate
3. spongy bone

Question 13

What is the cortical plate?

Answer 13

A site for skeletal muscles

Question 14

What does the cortical plate cover

Answer 14

The alveolar process

Question 15

What is the job of the cortical plate?

Answer 15

Provide strength and protection

Question 16

Maxillary vs. mandibular cortical plate

Answer 16

Cortical plate of the mandible is more dense than that of the maxilla. This affects the technique employed for injection of local anesthetic.
