Cryogenic treatment of martensitic shape memory nickel-titanium alloy

Recent introduction of shape memory (SM) Nickel-Titanium (NiTi) alloy is a major breakthrough in the field of Endodontics. Although flexibility of these instruments was enhanced, fracture of rotary endodontic instruments during instrumentation is an important challenge for the operator. Implementation of supplementary manufacturing methods that would improve the cyclic fatigue life of the instrument is desirable. Cryogenic treamtent is one such treatment that enhances the cyclic fatigue life of the instruments and minimize their fracture. This discusses about the impact of cryogenic treatment on the quality of root canal treatment provided to the patients in a most economical way.
