Since the introduction of Nickel-Titanium alloy as the material of choice for the manufacturing of endodontic rotary instruments, the success rate of the root canal therapies has been significantly increased. This success mainly arises from the properties of the Nickel-Titanium alloy: the biocompatibility, the superelasticity and the shape memory effect. Those characteristics have led to a reduction in time of endodontic treatments, a simplification of instrumentation procedures and an increase of predictability and effectiveness of endodontic treatments. Nevertheless, the intracanal separation of Nickel-Titanium rotary instruments is still a major concern of endodontists, with a consequent possible reduction in the outcome rate. As thoroughly demonstrated, the two main causes of intracanal separation of endodontic instruments are the cyclic fatigue and the torsional loads. As results, in order to reduce the percentage of intracanal separation research and manufacturers have been focused on the parameters that directly or indirectly influence mechanical properties of endodontic rotary instruments. This review describes the current state of the art regarding the Nickel-Titanium alloy in endodontics, the mechanical behavior of endodontic rotary instruments and the relative stresses acting on them during intracanal instrumentation, highlighting the limitation of the current literature.

The development of Superelastic nickel-titanium archwires has simplified the alignment phase of orthodontic treatment by permitting the use of highly flexible, resilient archwires and avoiding the need for complex loops. The majority of relatively high cost has led to sterilization and recycling of these wires by some clinicians. This study way designed to examine the effects of currently used infection contorl procedures on the mechanical properties of superelastic nickel-titanium alloy (SENTA®) archwires. One-hundred-and-forty lengths of a SENTA® wire were subjected to various sterilization and disinfection procedures. These included cold disinfection in 2 per cent glutaraladehyde solution for 3-and 24-hour cyles, and steam autoclaving. Single and double cycles were used. The properties investigated were the 0·1 per cent yield strengh, the ultimate tensile strength, and the flexural regidity. No statistically significant differences were found between the groups or against an untreated control.
