Cyclic fatigue resistance of new reciprocating files (Reciproc Blue, WaveOne Gold, and SmartTrack) in two different curved canals

Journal of Investigative and Clinical Dentistry, 2018
AbstractAimIn the present study, we compared the cyclic fatigue resistance (CFR) of Reciproc Blue, WaveOne Gold, and SmartTrack files in curved artificial canals.MethodsNinety new Reciproc Blue R25, WaveOne Gold Primary, and SmartTrack X1 files were tested in artificial canals with 45° and 60° angles of curvature.

Cyclic Fatigue of Reciproc and Reciproc Blue Nickel-titanium Reciprocating Files at Different Environmental Temperatures

Journal of Endodontics, 2018
The aim of the present study was to investigate the impact of ambient temperature on the life span of nickel-titanium (NiTi) files.Cyclic fatigue testing of NiTi instruments was performed in a stainless steel artificial canal. During the experiment, 4 different temperatures (0°C, 20°C, 35°C, and 39°C) were used in a thermostatic bath controlled using ...

Torsional Fatigue Resistance of Blue-treated Reciprocating Instruments

Journal of Endodontics, 2018
The aim of the present study was to evaluate the influence of blue thermal treatment on the torsional resistance behavior of M-Wire Reciproc files (VDW, Munich, Germany).Ten M-Wire Reciproc R25 (25/0.08v) and 10 Reciproc Blue R25 (25/0.08v, VDW) instruments were used. The torque and angle of rotation at failure of new instruments (n = 10) were measured

Torsional Resistance of WaveOne Gold and Reciproc Blue according to the Loading Methods

Journal of Endodontics, 2021
This study aimed to compare the torsional resistances and fracture modes of WaveOne Gold (Dentsply Sirona, Ballaigues, Switzerland) and Reciproc Blue (VDW, Munich, Germany) using the repetitive torsional loading (RTL) method and the conventional single-rotation (STL) method.A 3-mm file tip was fixed with a brass plate, and a torsional load was applied ...

Assortative Mating and Reciprocal Difference in the Blue–Snow Goose Complex

Nature, 1959
THE lesser snow goose Chen hyperborea and the blue goose Chen caerulescens are maintained as good species by the standard taxonomic works1 though the morphological difference between them is confined to colour of plumage. The geographical distribution of the two is different.
