Subject: [roots] Retreatment
Pt. has been referred by the oral surgeon! He was planned for
apectomy on both teeth by the original referral!!
Retreatment of #47 and 45. Coronal leakage on both with a huge
amount of debris/plaque inside the canals. Even the guttapercha
has been coloured by the bugs! 2 visits, adhesive build-up, MTA
on #45 due to resorption on the foramen and ISO# 60 diameter.

Beautifull work and documentation!!! Congratulations!!

Dear Dr.Schröder! Thanks for sharing this case! I love your style
of documentation.- Noemí Pascual
Jörg , could you tell how did you got throw the old filling?
did you use rotary instruments for removal previous obturation
solvents? did you have to negotiate any ledge? - Carlos Heilborn
Carlos, I used GG and tiny burs in the upper third, then I tried
rotaries, but I do not like the "explore" new land with rotating
instruments. ultrasound and microopener (reamer with a handle)
for the rest. A lot of warmed irigation. No solvents, because
I was afraid of pushing some gp into the lesion. (The removal of the
very last parts of gp in the distal took me 1 hour!)
The mesial canals have been very narrow, but with prebended
files/ ProFile 15/04 in a pecking motion and
some EDTA i was able to negotiate them. - Jörg
jorg, awesome work - Sashi
Thank you Sashi, just trying to give a little of the knowledge,I got
from people like you,- Jörg
Fantastic work Jorg. I see you isolate the complete qudrant. Is that
to help you do the build up at the end?
what matrix system do you use? - Venkat
Thank you Venkat,
you are right, it is to make sure, that I can do the build up no
matter what type or size of defect I have to
And in some cases it increases the space available for my instrumentation.
Of course it takes 1 or 2 minutes more, but at the end it is worth it.
If I did the Build-up in a previous visit, I will just dam one tooth.
I am using a partially matrix system formerly made by 3M.
I attach some pictures. - Jorg
Impeccable work and documentation. Your style rocks,- Thomas
Thank you once again Jorg for some great pictures.
I need your inputs regarding rubberdam placement.
As you see in the pics I attached, the interdental dam tears duirng
application and wedge placement, especially with tight contacts.
Hence I started using splitdam (2nd pic - not ideal but compromise)
does it matter?
Do you use a seperator before dam placement?
Do you use any lubricant?
What gauge dam do you use, Med or Heavy? - Venkat
it seems to me that there is too much tension on the interdental
part of your rubberdam examples. Do you use medium gauge?
Try to create more space between the holes, use holes 1 size smaller.
I prefer heavy gauge, although it is hard sometimes to get it through.
No lubricant ( for example shaving foam, because I hate the taste of it!)
and no seperators.
I prepare the dam for each patient. No holes in the dam to safe
10 seconds. So I am able to create the right distance between the holes.
The result is less tension on the interdental dam. My 2 cents - Jörg
