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.
Sealer: AH+

Kind regards - Rafaël





Nice case Rafaël!!! - 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 - Rafaël

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 - Rafaël

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  - Rafaël

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 200°C., but unless I use thermocouples to check this, I cannot be sure.

Hi Raf, Very nice job, A question though: why 200°C and not...for instance...330°C? - Amir

Hello Amir, Manufacturer's recommandations are 200°C. -Rafaël
