MB2 distance from MB1 – join MB1

#14 had large lesion on MB root and RCt by endo last year.  looked to me like missed MB1 and MB2 found.  With new decay and needing RCt retreat and apico best extract and do bridge, since #15 needs new crown also


See large lesion MB root
took me about 5-10 mintues to find and get 06 out MB1


Here you can see slight overfill on MB2 and MB1 was indeed missed.  I joked with my partner that the endodontist found his first MB2….too bad he missed the MB1.  There was a huge lesion on the MB root when this endo was done so it had 0% chance of healing from his treatment.


CaOH.  2mm piece SX at length MB2


Risk outweighs any benefit of retrieval at this point.  Piezo attempt for awhile but too far around last curve to even visualize at this point so quit
