pulpectomy - apex and anterior preps Flashcards
What is a primary tooth root canal?
How does a primary tooth root canal therapy vary?
Varies in primary teeth due to:
what must you have to be reasonably successful in a primary tooth root canal?
Endodontic procedures on primary teeth can be very difficult or impossible. To have a reasonable success you must have:
a) Accessible canals
b) Adequate supporting bone (no extensive PA or furcation bone loss)
if Accessible canals and Adequate supporting bone (no extensive PA or furcation bone loss) are not present what do you do?
what is irreversible pulpitis?
If it is irreversible pulpitis how is it completed?
Completed in ONE appointment.
Technique:
What cases should you select for non-vital primary tooth root canal ?
Case Selection:
How many appointments are needed for non-vital primary tooth root canals and what is done in each one?
done in three appointments
Appointment One:
For primary tooth root canal therapy what does the success depend on?
- Adequacy of root canal debridement.
- Antibacterial irrigation.
- Antibacterial filling material
Ca(OH)2 + CPC, ZnO + CPC, ZOE + FC
are strongest antibacterial
ZOE alone is medium antibacterial agent
What are the clinical and radiographic criterion for determining RCT success?
Criteria for determining RCT success: (Coll et al 1985)
what are the successes of different pulpectomy techniques?
What does pulpectomy success hav eto do with ZOE?
what does follow up have to do with anything?!?
Success rate: ~80%
What are the indications for non-vital immature permanent teeth pulpectomy?
what are the three options for non-vital immature permanent teeth pulpectomy?
How is revascularization performed for non-vital immature permanent teeth pulpectomy?
for non-vital immature permanent teeth pulpectomy apexification what is the frank technique?
and how is it done?
Frank (1966) developed a technique that stimulates the formation of an apical barrier to allow for conventional RCT to be done later.
how is MTA apexification done?
how are anterior preparations done?
reduce the tooth, you have a cap thing and you fill it with composite and squish it on the tooth after the tooth has been etched and bonded. then you cure it and take it off.
then with a scaler and sanding discs you clean it up.
