The purpose of this study was to compare the formation of microcracks after canal preparation performed with different single-file systems, including WaveOne Gold.
All the instruments tested created dentinal cracks. Within the limitations of this study, the flexibility of nickel-titanium instruments because of heat treatment seems to have a significant influence on dentinal crack formation. WaveOne Gold and HyFlex EDM caused less microcracks than the other instruments tested.
