:- Endodontic file separation is a common mishap
during cleaning and shaping procedures. Even though
there have been many recent advances in the material
science of endodontic files, instrument separation is
sometimes inevitable. There are several treatment options
available after instrument separation. In our case, a
patient was referred to us with a separated instrument
extending 4 mm beyond the apical foramen. Following the
re-treatment, a guided periapical surgery was planned,
and the patient was given long-term intracanal medication.
At 3 months, the patient was symptom-free, and the lesion
had reduced in size despite the fact that the endodontic file
was extending apically. At 6 months follow-up, uneventful
periapical healing occurred.
