Subject: [roots] Last five cases in a row

As previously stated, these cases were all done with bent 10-25 ss k-files, exploration to length using
M-4 handpiece where appropriate, Protaper flaring, Lightspeed apical prep.  Irrigated with NaOCl/EtOH and
Liquid EDTA and packed with calcium hydroxide/Chlorhexidine.

Then re-cleaned and irrigated with NaOCl/EtOH, Smear Clear, and Chlorhexidine. Obturated with
Resilon Simplifill and Epiphany sealer, and backfilled with pacmac/resilon cone and Epiphany sealer.

Do you think we need to do a final irrigation with Chlorhexidine on vital cases? Or on the first appointment
with either vital or non-vital cases? - DanS







I like them all Danimal but I think the 4th one looks a little short on both canals.  I will say this that
you get better deep shape than most  with LS and I like the puffs......dont know if Fred will!!
Very well done.......... Glenn



Nice work as always, Dan
I've wondered about CHX in vital cases myself ...... it's probably superfluous. However, I would have thought
that the first appointment in necrotic cases was THE indication. In fact, my interappointment canal dressings
are a combo of 2% CHX and Ca(OH)2 - Simon

Simon, I mix my Ca(OH)2 with CHX also, but then I do a separate rinse at the second appointment right before
filling.  Do you think I should do that rinse in the first appointment prior to placing my Ca(OH)2/CHX paste?
- DanS

Dan, my protocol at the irrigation stage (time spent after shaping dedicated solely to cycles of washing and
ulrasonication) is: after I've finished with the bleach + ethanol I flush with EDTA and THEN the 2% CHX goes in,
and that gets U/S agitation as well. Finally I simply inject the white stuff (Ultra-Cal) into the canals 'over'
the CHX, so it's 'mixed' in the canal. I don't routinely wash with CHX at the fill stage although I guess it's
not a bad idea!  - Simon

Dan, what are we going to do if Resilon turns out to be the junk Terry and others claim it to be? - Guy

Looks pretty good at two years, time will tell - DanS
