Subject: [roots] Sunday molar endo
Just a case I finished today. (A friend of mine, hence the working on sunday)
The diagnosis radiograph was taken with normal films, since in the first visit,
we had some problems with our digital system.
Today he came back for the second appointment.
Cleaning: NaOCl 3%, EDTA 17% final rinse, PUI and cone pumping.
Shaping: Hybrid technique protaper & profile, apical finishing with handfiles
Obturation: warm vertical compaction.
Kind regards - RafaŽl
Nice case RafaŽl!!! - Leandro Peraira
Raphael, I would like to have the following informations:
Did you cut a bit of your GP point after the Xray with GP inside the
roots canals and before you did your vertical compaction.
Yes, I shortened the ML guttapercha cone. All cones were size 30.06 and the
apical part was snipped with the tip snip from sybronendo. After the
gutta percha cone fit, I cut the ML guttapercha to a size 35 and
checked the length, which was now 0.5 mm shorter. I doubted to do the same
with the distals, but I got a good fit there, so I decided to leave
them as they were - RafaŽl
You write: vertical compaction ,which kind of compaction did you do ?.
I fitted the cone, then took the system B to 4 mm of working length and remove
the coronal part of the gutta percha. Then I condense it with a plugger.
Then I take the needle to about 3mm of working length and again remove the
coronal gutta percha. Then I place small amounts of guttapercha with the obtura and
condense them. About 2mm each time.
So it is the standard system B + obtura technique, with that difference that I
take the system B twice or sometimes more if needed deeper in the canal then
propagated by the manufacturer and their representatives.
I do not believe that 4mm is enough - RafaŽl
You finish the apical , third I mean, with hand file how far from the apex ?
I take the handfiles to working length, I keep the finishing (F1, F2, 30.06, 35.06)
rotaries to about 0.5mm from working length - RafaŽl
By the way you did a nice job - Paul NOYER
Thank you for your answer Raphael .
I though there was something like that because the AH+ usually with his too light body
makes more puff than you did . Another question : which temperature did you use ?
200 Degree C or more?
- Paul NOYER
It is 200įC., but unless I use thermocouples to check this, I cannot be sure.

Hi Raf, Very nice job, A question though: why 200įC and not...for instance...330įC? - Amir
Hello Amir, Manufacturer's recommandations are 200įC. -RafaŽl
