File breakage in Endodontics

# Which of the following describes the BEST management strategy for a separated instrument AFTER cleaning and shaping has occurred?
A. Do not attempt to remove and proceed to obturation
B. Place calcium hydroxide
C. Attempt to bypass the instrument

The correct answer is A. Do not attempt to remove and proceed to obturation.

If an instrument separates at the filling/obturation stage, the instrument does NOT require removal because the etiology of the problem has already been resolved
through cleaning and shaping of the canals.

The prognosis for the tooth will be
considered more favorable if the infected
dentin has already been debrided from the
canal.

The prognosis for the tooth will also be
considered more favorably the more apical
the instrument separation occurred.
