How much bacteria reduction is good enough for healing to come? 
I should add here for healing not only to come but also to last 
long term.

In the case attached healing came in three months although 
I missed the lingual canal. For me this means that my cleaning 
protocol was good enough in the reduction of bacteria
for healing to be promoted ( even if I missed a lingual canal). 
Of course I new from the start that I should try and negotiate 
this missed canal and that the crowns should be removed.
The patient disappeared and returned 3 months later. 
The periapical lesion seemed healed but I was sure the  healing 
result wouldn't last long term. So I reentered and cleaned the 
missed canal!! Healing in endodontics is not the only issue of 
interest, long term healing is. So what is the critical bacterial 
reduction for healing to Last long term. That's why we need long 
term healed cases to enhance the power of our treatment protocols.
