Subject: [roots] retreatment
Here is a retreatment case. Tooth was treated some months ago. After that, it was sensitive to cold stimuli for some weeks...
An untreated canal is obvious on the pre-op RX. The dentin map of the pulp chamber floor makes it difficult to understand how
the distolingual canal could be missed! All canals cleaned, shapes and disinfected to full WL, warm vertical obturation (1 step).
Critique is always welcome! - Maarten Meire
Great job, congratulations - Miguel González Rodríguez
excellent retreatment work.have you retreated all the canals and what is the best method to remove gp in case of retreatment.
- Pavan Nallapati
Thx Pavan. All the canals were retreated (always). I remove gp with GG's and Profiles (usually a 25 .06) @ 600 rpm - Maarten
Hello Maarten- Can you discuss your instrumentation and obturation technique? Nice case.....Drew.
Congratulations Maarten! I would like to know also your instrumentation and obturation techniques? sessions? - Noemí
Thank you, Drew and Noemi! Instrumentation with SS files 08 10 15 and Protapers in this case. Obturation with GP,
AH plus sealer and warm vertical condensation (Schilder). This was a single visit treatment - Maarten
Congratulations Maaten, excellent photo, what camera do you use? - Helder Pavanelli
Thank you Helder. The camera is a Canon EOS 30D, mounted on a 50/50 beam splitter via a f=340mm Zeiss adapter to a
Zeiss ProErgo with xenon light. These images were not as sharp as I wanted them, though. Scope photography is far
from easy (at least in my hands)! - Maarten
Hi Maarten, is not only a beautiful image, but the case is very good the preparation for filling.
uses Touch'n Heat and what pluggers? congratulations - Marino
Great case Maarten...........the reason I feel the first operator missed out on the second distal is prob. that in cases
with a second distal root the Distolingual canal is situated more in the distolingual corner and can be missed if the operator
doesn't have an intent on finding it ......anyways all the canals were under-treated and the tooth has to be retreated sooner
or later....lucky the patient came to you - Sachin
I have had Profile breakages that way, what's your experience? i have since discontinued use of Profiles that way.
Coulld you elaborate? - Sanjay Jamdade
