Subject: [roots] Last case of the day.

Nothing special, but I wanted to post one :)
The last case I did today.
2.6 which was necrotic due to a big composite restoration.
DB = 20mm MAF = 30
MB1 = 18,5mm MAF = 30
MB2 = 19mm MAF = 30
P = 21mm MAF = 30

Everything is shaped until a protaper F1 and then apically finished with a profile 30.04. Cleaned with
NaOCl 3% and a final rinse with EDTA 17%. PUI at the end of treatment for about 3x15 sec in every canal.
Temporary restoration in glass ionomer.
Cold lateral condensation and AH+ as sealer - Rafaël Michiels

Very nice case. - Guy

Rafaël , well done but it is not the restoration itself but the leakage caused by poor adaptation of
the material - Bart

Thanks Bart and Guy.

Yeah it could be leakage from the poorly adapted composite, or just the composite being too big and hence
too close to the pulp, or too much heating when drilling the cavity. Or just a reaction on the composite
(some monomer leftovers that did not polymerize). But leakage indeed is the most common cause - Rafaël Michiels
