Subject: [roots] Middle distal canal

Re-tx case started yesterday.  I did my best to talk the old fellow into ext/implant, but he wanted to try to save
the tooth.....I guess at his age "long term prognosis" has a different meaning.    I find that in a lot of these cases,
the more you try to talk down the prognosis, and the more reluctant you are to take on the case, the more some of
these people want you to do it....pretty interesting - Mark Dreyer



How often have you found this mark, and do you think it is as most mm, more of an isthmus between the other two
than a separate patent canal?  The only 5 bangers I’ve had have been those with mm’s - gary

Gary, I don't find this often.  All 3 canals drained separately, so it doesn't look like they're connected,
but I'll see him for one more visit and it's possible I'll find they connect once I complete
the cleaning/shaping - Mark Dreyer
