03 Pulpotomy Flashcards
What exactly is a pulpotomy
The amputation of the CORONAL portion of the pulp
After a pulpotomy, are the rest of the nerves in the roots still vital?
Yes
What is the first step in the pulpotomy technique?
Remove caries and determine site of pulp exposure
After caries are removed, what comes next
Remove the roof of the pulp chamber
Once the roof of the pulp is removed, what is the next step
Removal of the coronal pulp tissue
What comes after removing the pulp tissue
Control bleeding
What are the 3 main types of medicament for the pulp
Formocresol
Ferric Sulfate
MTA
What does MTA stand for
Mineral Trioxide Aggregate
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
How does the pulp in the canals look?
What is the Formocresol Pulpotomy Technique
- Control Bleeding
- APply formocresol for 5 minutes
- Place a cotton pellet for 5 minutes
- Place a dry cotton pellet over wet pellet to absorb extra medicament
- Remove pellets
- Fill chamber with cement/IRM and restore
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
What is ferric sulfate used for
to stop bleeding
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
Cover pulp stumps with zinc-oxide-eugenol (IRM) or GI
What chemical is IRM
Zinc-oxide-eugenol
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
