Subject: [roots] Retreatment 15


Retreatment with some surprise. I expecated a full metal core, but found a metal post fixed with composite. Same procedure as removal of a metal post and core.
Finally it moved out. 2 canals merging into a big one. CaOH2 for 3 weeks and temporary build-up. Crown lenghtening will follow. Note the discoloration after
irrigation in the area of the fistula. Pt. has been free of symptoms after the first visit.

Love it,  What do you use to irigate the Sinus Tract ? CHX XXX% ? - Thomas

Thomas, I did not irrigate it on purpose. Must have happened while irrigating the canal. Call this a Bleach Accidnet? - Jörg

Jorg, It happens. Don't call it a Hypochlorite accident. I had one, and believe me you will never forget it. - Thomas

Hi Jorg, What kind of core build up did you go in for in this case? - Sachin

Sachin, I used a dual curing composite called Rebilda made bei Voco in combination with Syntac Classic by Vivadent - Jörg

Why do you rate it above cast cores? I still go in for cast cores and economy being the main reason and I ask for the advantages of a dual cure buildup
only to shift over if there is a big disadvantage with the cast cores - Sachin

Sachin, I just see a disadvantage for cast cores inthe need to remove more toothstructure in order to avoid undercuts (right word?). In my hands
I never had a VRF with Fiberposts but some with casted cores. The e-modul of casted cores is different to that from teeth, so it makes sense to me to
use composite with fibreposts. Hope it makes sence - Jörg

Modulus of elasticity makes a lot of sense ...:-)...thanks Jorg - Sachin

Hi Thomas , Do we really need to irrigate the sinus tract ? Once we have worked upon the source of infection ( the root canal system) I think there is
no need to irrigate the sinus tract. Plz correct me if I am wrong. - Sachin
