Assessment of the Separation Incidence of Reciprocating WaveOne Files: A Prospective Clinical Study
Journal of Endodontics, 2014Despite metallurgical advancements in the nickel-titanium file manufacturing process, file separation remains a concern. The purpose of this prospective clinical study was to assess the separation incidence of the reciprocating WaveOne file (Dentsply Tulsa Dental Specialties, Tulsa, OK) when used to prepare root canals of posterior teeth.File ...

Influence of kinematics on the cyclic fatigue of ProTaper Gold and WaveOne Gold
Saudi Endodontic Journal, 2020Introduction: The aim of the study is to assess the difference in the dynamic cyclic fatigue resistance of ProTaper Gold (PTG) and WaveOne Gold (WOG) files tested in clockwise and counterclockwise continuous rotation against two different reciprocal motions. Materials and Methods: A total of 200 files were tested at 300 rpm.

Metallurgical analysis and fatigue resistance of WaveOne and ProTaper Nickel–Titanium instruments
Odontology, 2013The aim of the study was to evaluate cyclic fatigue resistance of two NiTi instruments and to analyse their surface, fractographic and matrix morphology under ESEM/EDS and optical microscopy. WaveOne Primary and ProTaper Universal F2 brand new instruments were subjected to fatigue testing in an artificial canal with 5.0 mm radius and 60° angle of ...

Influence of the Preparation Order in Four-Canal Maxillary Molars with WaveOne Gold System
Journal of Endodontics, 2020The aim of this study was to evaluate the effect of the order of preparation of four-canal maxillary molars on volume variation, instrument deformation, cyclic fatigue, and preparation time by using the WaveOne Gold Primary (WOG 25.07).We selected 48 permanent, human, four-canal maxillary molars.

Asymptotic Behaviour of a Solitary Waveon a Random Electric Transmission Line
Journal of the Physical Society of Japan, 1991Weak nonlinear waves on an LC ladder line with small random imhomogeneities are investigated. By means of a nonlinear perturbation method, a nonlinear integro-differential equation which describes asymptotic behaviour of weak nonlinear waves on the line is derived from the basic system of equations.
