Nickel-titanium (NiTi) instruments have become popular in endodontics because of their greater flexibility compared to stainless steel instruments, which results in fewer procedural errors 1, 3. It involves removal of pulpal tissue and infected dentin, reducing microbial count, creating access for irrigants and intracanal medicament delivery and optimizing root canal system for root canal filling materials 1, 2. Root canal preparation is a central step in endodontic therapy, which influences the success of the procedure. WOG files showed more surface deterioration and less passive layer formation as compared to TFA and XPS systems. XRD exhibited NiTi phases with diffraction peaks. High resolution of Ti 2p spectrum show distinctive peaks with binding energies dominating in WOG, XPS and TFA file system. Raman peak at 540–545 cm −1 is attributed to Cr 2O 3. Ni 2+ concentration from WOG was 171.2 μg/L.
SEM of WOG instrument showed scraping surface defects. XPS file system showed minimal grooves on surface. After allocating scan line shifts like in WOG, mechanical deformation was shown using first order polynomials. X-ray photoelectron spectroscopy (XPS) analysis was done before and after use. Ni 2+ release was measured at 1, 3, 5 and 7 days. Nanoindentation was carried out to characterize surface topography. File morphology was analyzed using scanning electron microscopy X-ray diffraction analysis was performed before and after use along with Raman spectroscopy. Standardized in vitro shaping was performed in presence of 5.25% sodium hypochlorite. Helpful pre-programmed motor settings are available.To evaluate structural profiles and mechanical behaviour of WaveOne Gold (WOG), Twisted File Adaptive (TFA) and XP-endo shaper (XPS) instruments after root canal preparation. The WaveOne® Gold Glider is only for use in reciprocating motion with compatible Dentsply Sirona motors.The WaveOne® Gold family now includes a single glide path file with reciprocating motion for simplicity from the start.Part of a complete solution that includes obturation products designed to match the shapes created by WaveOne® Gold files.
A complete solution with dedicated obturation products, including variable tapered gutta‐percha points specially molded to fit canals prepared with WaveOne Gold files.Single patient use policy (anti‐sterilization ABS ring).Same reciprocating motion (Compatibility XS+ / iQ WaveOne settings).A single file (Primary size) for the majority of canals (~80%).WaveOne Gold, as the successor of WaveOne, keeps the same philosophy of simplicity as the first generation that was launched in 2011, with strong additional benefits that enhance the confidence level of dentists. This new solution represents one of the pillars of Dentsply Sirona Endodontics’s “Choose Your Endo Solution” concept, along with ProTaper Next for continuous rotation. WaveOne Gold is the latest generation of reciprocating technology developed by Dentsply Sirona Endodontics in collaboration with four endodontic key opinion leaders.
