Аннотация
The impact of autoclave sterilization on the cyclic fatigue resistance (CFR) of three heat-treated NiTi systems used in endodontics is concern. Therefore, it is of interest to compare the cyclic fatigue resistance (CFR) of three heat-treated NiTi systems (ProTaper Gold, Edge Taper Platinum and HyFlex EDM) following autoclave sterilization. Hence, ninety files were tested under artificial canals after 0, 3 and 5 autoclave cycles. Results showed HyFlex EDM had the highest CFR at all intervals, followed by Edge Taper Platinum and ProTaper Gold. Autoclave sterilization significantly improved CFR for HyFlex EDM and Edge Taper Platinum, while ProTaper Gold showed no significant change. SEM analysis revealed fewer machining defects in HyFlex EDM. Thus, insights into the cyclic fatigue resistance (CFR) of three heat-treated NiTi systems after autoclave sterilization, contributing to the understanding of the performance of endodontic files under stress.
