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 ...

Fracture Risk of Endodontic Files: Clinical Analysis of Reciproc and X1 Blue After Multiple Uses

Australian Endodontic Journal
ABSTRACT This retrospective study assessed the fracture incidence of Reciproc R25 and X1 Blue 25.06 files after up to three uses in 1720 root canals (1620 teeth) treated by a specialist. A standardised protocol was followed for all procedures. Periapical radiographs with the fractured instrument were used to evaluate the fragment's location and size ...

Surface Nanoscale Profile of WaveOne, WaveOne Gold, Reciproc, and Reciproc Blue, Before and After Root Canal Preparation

Odontology / the Society of the Nippon Dental University, 2019
This study aimed to compare the surface topographies and nanoscale profiles of intact and used WaveOne, WaveOne Gold, Reciproc, and Reciproc blue nickel-titanium (NiTi) instruments. Sixteen NiTi instruments were evaluated; four from each one of WaveOne (25/0.08), WaveOne Gold (25/0.07), Reciproc (25/0.08), and Reciproc blue (25/0.08) files.

Effect of MT Technology of Heat Treatment on Reciproc: Comparison of Reciproc, Reciproc Blue, and Reciproc MT

Journal of Endodontics
This study aimed to evaluate the effects from the memory-triple (MT) heat treatment on the fatigue resistance of the Reciproc by comparison with the file systems of same geometry.Reciproc files subjected to MT heat treatment technology were designated as Group RMT and were compared with the original Reciproc (Group REC) and Reciproc Blue (Group REB ...

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.

Shaping ability of reciprocating single-file systems in severely curved canals: WaveOne and Reciproc versus WaveOne Gold and Reciproc blue

Odontology, 2018
The aim was to compare the canal straightening of M-wire [Reciproc (VDW, Munich, Germany) and WaveOne (Dentsply Maillefer, Ballaigues, Switzerland)] and gold- and blue-wire heat-treated [Reciproc blue (VDW) and WaveOne Gold (Dentsply Maillefer)] instruments in severely curved root canals.

Evaluation of apical extrusion of debris after instrumentation with two reciprocating systems: RC Blue and Reciproc Blue

Medical Research Archives
Introduction: The aim of this study was to quantify the debris extruded after instrumentation with two reciprocating systems. Materials and Methods: Thirty-six mandibular premolars with a single straight root canal and apical diameter compatible with a size 15 K-file were randomly divided into two groups (n = 18) according to the instrument used: RC ...

Cyclic fatigue of Reciproc Blue and Reciproc instruments exposed to intracanal temperature in simulated severe apical curvature

Clinical Oral Investigations, 2018
The aim of this study was to evaluate the cyclic fatigue resistance of Reciproc and Reciproc Blue by testing in a severe apical curvature at intracanal temperature.Eighteen Reciproc R25 (25.08) and Reciproc Blue (25.08) instruments were tested in a cyclic fatigue device at body temperature (37 °C) using a stainless steel block with an artificial canal ...

Reciprocity and partner preference in grooming of female blue monkeys

International Journal of Primatology, 1991
Grooming among adult and older juvenile females in a wild group of blue monkeys (Cercopithecus mitis stuhlmanni) is analyzed and related to agonistic behavior. Both grooming and agonistic behavior were less frequent than would be expected in baboon and macaque groups.
