After an interim treatment period of calcium hydroxide insertion, the debrided and disinfected canals
were obturated using thermo-softened gutta-percha and resin sealer.  The floor of the chamber and
orifice interface of dentin and gutta-percha were covered with calcium hydroxide to prevent recontamination.
You will need to refresh the axial dentin and bond the chamber prior to fabricating the post/core complex.
All procedures are performed using a range of 4.5 to 16x magnification.  BioPure MTAD was used as the final
irrigant. CLP will be necessary in order to restore the tooth on sound margins

Aloha Ken - I like when you post cases.  We're all trying to be like Sashi.
What's up with the "calcium hydroxide" on the floor of the chamber and gutta percha to prevent recontamination?

Decay at the gingival margin......CLP needed, I don't bond in those cases.........might obscure areas of decay
........I leave Ca(OH)2 in the orifices....light cure temp material in the chamber floor and temp and call the
DDS immediately and advise them that time is of the essence, no delay..........I've gotten caught were even
though I ask them to remove any flash et al of the Purple Permaflo, did not happen.......just an extra step
to not leave open space.

NOW IF JOHN BERNHARD OF UPI would develop those little sponges with the CHX dispenser we've talked about
forever.........different scales of excellence..........I might not be able to bond a dime to Pannkuk's butt,
but I know a few bondodontists who could.............hell with all that hair anything would stick -  K
