for me Broken file retrieval is more predictable than bypass
but as the BF located more apically.... I prefer bypass over retrieval
for me dentin Preservation is a 1st priority....as BF locate more apically that means more dentin to remove for retrieval
bypass is more conservative option
another tip: if any errors happens during RCT try to finish the easy part of RCT and delay the management of the errors as possible to a 2nd visit
to start fresh... and have a plan and proper tools
using File Sequence Cycling technique for bypass
