1
Q

Define indirect pulp cap

A
  • Biocompatible material placed in deep carious tooth approximating the pulp
  • No signs of pulpal degeneration or exposure
2
Q

Define Direct pulp cap

A

Pinpoint mechanical exposure during prep covered with biocompatible material

3
Q

Define pulpotomy

A

-Removal of pulp in the chamber with the intent to maintain the vitality of the radicular pulp

4
Q

Define pulpectomy

A

Removal of entire pulp (coronal and radicular)

5
Q

What is the typical restoration for a primary tooth after indirect pulp cap

SSC

6
Q

What materials can be used for indirect pulp capping

A
  • RMGI (vitrebond)

- CaOH2 followed by vitrebond

7
Q

Which has a higher success rate indirect pulp capping or pulpotomy for primary teeth

A

indirect pulp cap

8
Q

Success of indirect pulp capping is dependent on what

A

accurate pulpal diagnosis

9
Q

Indirect pulp capping will not be successful if

A
  • Furcation RL (or PA RL)

- Pathologic root resorption

10
Q

What materials are used for direct pulp cap

A

MTA or CaOh2

11
Q

Direct pulp cap is not recommended for pulp exposures that are _

A

carious (should be a mechanical pulp exposure)

12
Q

What should you due for a carious pulp exposure

A

pulpotomy

13
Q

(T/F) After a pulpotomy the tooth should remain in place and exfoliate at the normal time

A

t

14
Q

After a pulpotomy you may see _ resorption but you should not see

A

internal… pathologic external root resorption

15
Q

What are the criteria for a primary tooth pulpotomy

A
  • Pulp exposure
  • Dx normal or reversible pulpitis (reversible pulptitis= pain with stimulus no spontaneous pain)
  • Clinical exam (no mobility, fistula, no pain with percusion and must be restorable)
  • Radiographic exam (no furcation involvement or PA RL Want at least 2/3rds of the root remaining)
16
Q

Contraindications for a pulpotomy

A
  • Pulpal Dx or irreversible pulpitis (spontaneous pain- does your child wake up at night with a toothache)
  • Clinical pathology (Swelling, fistula, pathologic mobility, pain with percussion)
  • Radiographic pathology (Furcation/periapical lucency, external root resorption)
  • Unrestorable tooth
  • Excessive bleeding after coronal pulp amputation
  • No bleeding after coronal pulp amputation (necrosis)
17
Q

Preparation of a tooth for a SSC should occur (before/after) the pulpectomy

A

before

18
Q

Coronal pulp removal should be done with what bur

A

Round bur slow speed

19
Q

Hemorrhagic pulp means what

A

inflammation has spread to radicular pulp

20
Q

During a pulpotomy the chamber should be treated with any one of these three medicaments

A
  • Foromcresol
  • Ferric sulfate
  • MTA
21
Q

Coronal filling after a pulpotomy should be done with

A

IRM

22
Q

The ideal pulpotomy medicament has what properteries

A

Bactericisal
Harmless to pulp and surroundign tissues
Promote healing of radicular pulp
Not interfere with physiologic process of root resorption

23
Q

Foromcresol should be placed in the chamber for how long

A

5 mins

24
Q

Foromcresol can be diluted to what ratio

A

5:1

25
Q

What is the gold standard medicament for pulpotomies

A

formocresol

26
Q

What is formocresol made of

A

formaldehyde and cresol

27
Q

Is foromcresol bactericidal

A

yes

28
Q

What are the cons of formocresol

A
  • Can cause inflammarory responses or necrosis in remaining radicular pulp (leads to internal root resorption)
  • Potentially immunogenic, carcinogenic (formaldehyde)
29
Q

Success rate of formocresol is

A

70-90%

30
Q

Directions for ferric sulfate use are

A

apply to pulp chamber for 10-15 sec and rinse

-Seals BVs –> hemostasis

31
Q

Success rate of ferric sulfate is

A

81-97%

32
Q

Is ferric sulfate bactericidal

A

no

33
Q

Which material for pulpotomies has the highest success rate

A

MTA (Close to 100%)

34
Q

MTA sets in the presence of what

A

moisture

Q

pH of MTA is _ similar to that of _

A

12.5… CaOH2

36
Q

Is MTA antimicrobial

A

yes

37

no
