This study compared 120 WaveOne Gold primary, Reciproc R25 and WaveOne primary reciprocating files in an artificial canal with an s-shape to test resistance to cyclic fatigue. Forty files of each brand were tested and the number of rotations prior to fracture along with the length of each fractured fragment were recorded. The study concluded that WaveOne Gold primary files exhibited greater resistance to cyclic fatigue in this instance than both the other file groups.
