Using nickel titanium (NiTi) rotary instruments during root canal preparation does not reduce the risk of separation because this instrument is often overused or used incorrectly.8 Several factors determine the prognosis of broken file removal, such as the type of separated instrument, canal depth, pulp status, and canal infection.8 NiTi fragments are more difficult to remove than stainless steel ones because they are prone to further breakage when using an ultrasonic instrument for retrieval.9 If the fragment is located deeper in the canal, a significant amount of dentin is lost in the process of fragment retrieval, resulting in reduced root strength.	cache/mkg-42191.pdf	txt/mkg-42191.txt
