Pulp Therapy Flashcards
Name some pulpotomy medicaments (other than Formocresol)
Coagulants - Ferric Sulfate
Mineralizing/Bacterialstatic agents - CaOH
Other - electro-surg, laser, pressure, MTA
How does Ferric Sulphate work? What is it used for?
- Used as a coagulation and he static agent (blood proteins react with ferric and sulphate ions with acidic pH solution)
- Agglutinate do proteins form plugs that occlude capillary orifices
- No concerns about toxicity or harmful effects
- Not an antibacterial
Ferric sulphate is used for pulpotomy treatment
What is MTA? What is it used for?
MTA is Mineral Trioxide Aggregate (MTA)
Made of:
- tricalcium silicate
- dicalcium silicate
- tricalium aluminate
- calcium sulfate dihydrate
- bismuth oxide
Hardens in dampness or blood. It is an anti-microbial to facultative bacteria. Causes dentin bridge formation with less inflammation and less pulp all necrosis than CaOH. It is not hemostatic
What induced formation of dentin at a faster rate - CaOH or MTA?
MTA and it produces more complete dentin bridges
MTA has a very high success rate but it is expensive, technique sensitive, and has difficult handling properties
What is the difference in patient results between Formocresol and Ferric sulfate?
There is no difference
Which is better for a pulpotomy procedure? CaOH or Formocresol?
Formocresol is a much better option
What is better for pulpotomy? Sodium hypochlorite or Formocresol?
No difference but if there is internal resorption it is most likely due to failure in hypochlorite
What is better in a pulpotomy procedure – Formocresol or MTA?
MTA proved to have a lower failure rate with less occurrence of internal root resorption
What is the restoration of choice for primary teeth after a pulpotomy or pulpectomy?
SCC
How is timing important to preventing failure of restoration? (SCC and pulp treatment)
SCC with finished pulp at the same visit has a higher chance of success (82%) than if don’t at a later visit.
SCC with indirect pulp at same visit success rate is 93%
What is Formocresol?
