    Reciprocating motions has grown in popularity in the last ten years and many researches were published in the last years 24 This article has been cited by other articles in PMC.

    The recent literature demonstrated the importance of the angles of reciprocating motion in the cyclic fatigue life of NiTi rotary instruments The device consists of a main platform to which is connected the electric handpiece and a stainless-steel block containing the artificial canals.

    Although the Wave One motion is not clearly disclosed by the manufacturers, the present study was not influenced by the reciprocating angles, because both the instruments have been rotated using the Wave One proprietary motion.

    All instruments were inserted at the same length 18mm and then rotated in reciprocating motion until fracture occurred.

    WaveOne Gold instruments have a modified convex triangular cross-section at the tip and a convex triangular cross-section in the middle and a coronal portion that is similar to the cross-section of the ProTaper instruments 31 The null hypothesis was that there are no differences between the two tested instruments in cyclic fatigue lifespan. Figure 1. To reach this aim, the development has followed mostly three different ways: the changing in the instruments design, the heat treatments of the alloy and the use of different kind of motions 19 -

    Material and Methods Two groups of 20 different NiTi endodontic instruments of identical tip size of 0. WaveOne Gold instruments have a modified convex triangular cross-section at the tip and a convex triangular cross-section in the middle and a coronal portion that is similar to the cross-section of the ProTaper instruments 31 The microcracks deepening, as a result of each loading cycle, leads to the complete instrument separation 16 - Rezifllow instruments were associated with a significantly higher cyclic fatigue resistance than WaveOne Gold instruments.

    Starting from the manufacturing process, each instrument shows some irregularities and defects and their distribution influences the fracture resistance of the resulting product The null hypothesis was that there are no differences between the two tested instruments in cyclic fatigue lifespan.
