Remove caries and determine site of pulp exposure

4

5

Once the roof of the pulp is removed, what is the next step

Removal of the coronal pulp tissue

6

What comes after removing the pulp tissue

Control bleeding

7

What are the 3 main types of medicament for the pulp

Formocresol
Ferric Sulfate
MTA

8

Mineral Trioxide Aggregate

9

What do you want to determine from a pulp exposure standpoint?

Nature of the exposure

Bleeding

Appearance of the pulp tissue

Can bleeding be controlled in 3-5 minutes

Does the blood appear red and normal

4. Place a dry cotton pellet over wet pellet to absorb extra medicament
5. Remove pellets
6. Fill chamber with cement/IRM and restore

11

How does Formocresol work

Bacteriocidal effect
Devitalizing effect
Converts bacteria and pulp into inert compounds

Inactivates oxidative enzymes in the pulp

Renders pulp inert and resistant to enzymatic breakdown

12

to stop bleeding

13

How do you use ferric sulfate?

Place FeSO4 using syringe with cotton tip or apply with cotton pellet for 15 seconds

Rinse with water and dry gently with cotton pellet

Zinc-oxide-eugenol

15

What is accomplished in a successful pulpotomy

Elimination of infection

Tooth is preserved in healthy, non-pathogenic form

Arch space is maintained

Normal resorption of primary tooth and eruption of permanent successor
