Subject: [roots] Difficult calcificated central

A case I did this morning. Patient was referred, because the dentist could
not find the canal.

Reason for consulting his dentist was heavy continuous pain, which the
patient could localize to the left central.

I removed the temporary restoration and cotton pellet and from then on took
my LN bur until I saw where the canal used to be. After a while I could
enter the canal with a K-file .08. After destroying a dozen of .08 and
.10 K-files I could go to WL with a .15 and from then on I took my
protapers to WL.

I shaped until a protaper F3 and finished apically with a .40 K-file.
I rinsed copiously with NaOCl 3% which was activated with US from time to
time. A final rinse with EDTA 17% wich was activated with US and then
everything was again rinsed with NaOCl (with again PUI)
I obturated the canal with GP and AH+ following CLC technique.
Tooth was temporarily restored with GIC (Ketac Fill)

Definitive restoration will be done by referring dentist and will be:
Removal of Mesial and Distal composite resin and making a new composite
restoration Mes,Dis & Pal. Also: reevaluation of tooth 1.2 was advised,
since it looks very compromised - Rafaël





Rafael, that was a tough case!
But i hardly can see F3 shape there... what was your sequence? - Dmitri

Hello Dmitri, Sequence was standard Protaper Sequence,
S1, S2, F1, F2 & F3 in that order. - Rafaël
