pulp protection quiz

Question 1

How long do you review the bleeding control of an exposed pulp before deciding it requires a partial pulpotomy?

Answer 1

5 minutes

Question 2

Name 3 symptoms of irreversible pulpitis.

Answer 2

1. Poorly localised to 1 tooth.
2. Spontaneous pain.
3. Pain referred to the face or jaw.

Question 3

True or false: Calcium Hydroxide is the material of choice for a direct pulp cap?

Answer 3

False -
calcium silicate cements (e.g: biodentine or MTA) are the preferred material.

if these are not available, calcium hydroxide is an acceptable alternative

Question 4

Which procedure involves the application of a biomaterial onto a dentine barrier in an indirect one-stage selective carious-tissue removal technique.
Removal to soft or firm dentine.
Immediate placement of a permanent restoration.

Answer 4

Selective Carious Tissue Removal

Question 5

Which procedure involves the application of a biomaterial onto a dentine barrier in an indirect one-stage carious-tissue removal technique generally to hard dentine?
Considered more aggressive than selective carious-tissue removal in one-stage and stepwise excavation.
Leaves neither soft nor firm carious dentine behind.

Answer 5

Indirect pulp capping.

Question 6

Which procedure involves the application of a biomaterial in an indirect two-stage selective tissue removal technique.
Temporary restoration placement between visits and re-entry after 6-12 months.
First stage involves selective carious removal to soft dentine to an extent that facilitates proper placement of a temporary restoration.
Second stage involves removal to firm dentine.
Final placement of a permanent restoration.

Answer 6

Stepwise Excavation

Question 7

Which procedure involves application of a biomaterial directly onto the exposed pulp, prior to immediate placement of a permanent restoration following the preservation of an aseptic working field.

Answer 7

Direct pulp capping.

Question 8

Which procedure involves the removal of a small portion of coronal pulp tissue after exposure, followed by application of a biomaterial directly onto the remaining pulp tissue prior to the placement of a permanent restoration?

Answer 8

Partial Pulpotomy.

Question 9

What is a Class I pulp exposure?

Answer 9

EXPOSURE DUE TO TRAUMATIC INJURY TO THE TOOTH OR IATROGENIC.

No preoperative presence of a deep carious lesion.
The pulp exposure is through sound dentine with the underlying pulp tissue being healthy.

Question 10

What is a Class II pulp exposure?

Answer 10

Preoperative presence of a deep carious lesion where exposure is through a zone of bacterial contamination and the pulp is inflamed.

Question 11

Properties of a deeper cavity?

Answer 11

1. Greater number of tubules exposed.
2. Tubules have a greater diameter.
3. More damage caused to odontoblast processes.
4. Have greater fluid flow.
5. Wet environment for bonding.
6. Allow greater pulpal irritation from restorative materials.

Question 12

What is the success rate of direct pulp capping with either a CSC or calcium hydroxide at one year?

Answer 12

90%

Question 13

True or False - Electric pulp tests are the first line choice for testing non vital and vital teeth.

Answer 13

False -
Cold tests should be used as a first line.

EPTs are accurate when testing vital teeth but poor when testing non-vital teeth.

Question 14

Describe deep caries.

Answer 14

Caries reaching the inner 1/3 of dentine but with a zone of hard or firm dentine between the caries and the pulp.

Question 15

How would you describe extremely deep caries?

Answer 15

Caries penetrating the entire thickness of dentine.

Question 16

Which 3 main sources is the pulp under threat from?

Answer 16

1. Trauma
2. Caries
3. Iatrogenic Damage
