Term
The coronal pulp is found within the crown of the tooth be able to point out where the pulp horns horns are on the coronal pulp [image] |
|
Definition
| They are the smaller extensions at the outer top most aspect of the pulp |
|
|
Term
Compair and contrast the Primary, Secondary, and Tertiary dentin types. |
|
Definition
Primary: The first dentin formed even before the apex of the tooth is formed Secondary: Starts to form after apical foramen is formed.Continues to grow slowly throughout lifetime and is less meneralized than primary. Tertiary: Reparative dentin. This forms fast in localized areas that have been exposed to decay, attrition, and recession |
|
|
Term
| What is the correct make up of dentin? |
|
Definition
A crystalline material mainly made up of calcium hydroxyapaptite 70% inorganic 20% organic 10% water Dentin crystals are smaller than enamel and make up the bulk of the tooth structure helping to protect the pulp |

Term
Explain what the pulpal core is? |
|
Definition
| Located in the center of the pulp chamber, which, like the sell-rich zone, has many cells and extensive vascular supply |
|
|
Term
| List the microscopic zones from the outside going in |
|
Definition
1.Odontoblastic layer 2. Cell-free zone 3. Cell rich zone 4. Pulpal core |
|
|
Term
| Descripe the odontoblastic layer |
|
Definition
| Lines the outer wall and consists of the cell bodies of odontoblasts. Secondary and tertiary dentin can be found here. Parts of nerve bodies can be found here. |
|
|
Term
|
Definition
| Few cells found here mostly just nerves and capillary plexus make up this layer |
|
|
Term
| Describe the cell-rich layer. |
|
Definition
| Very extensive vascular system with an increased density of cells |
|
|
Term
| Describe an accessory canal |
|
Definition
| An extra opening from the pulp to the PDL and is associated directly with the pulp. Hard to see on an x-ray |
|
|
Term
Describe what an apical foramen is |
|
Definition
| An opening at the apex of the tooth from the puplal chamber that allows arteries, veins, lymph, and nerves to enter and exit. The last portion of the of the tooth to form. |
|
|
Term
| Describe the portions of the pulpal chamber |
|
Definition
Coronal: pulp inside the crown of the tooth Radicular: Pulp extending down into the roots of the tooth from the cervical portion to the apex |
