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. - Jörg Schröder









Beautifull work and documentation!!! Congratulations!! - Carlos Heilborn

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
handle with.

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




Hi 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
