Histological evaluation of the cleaning effectiveness of two reciprocating single-file systems in severely curved root canals: Reciproc versus waveOne
(2015-01-01)
Objective: The aim of this study was to evaluate the cleaning effectiveness achieved with two reciprocating single-file systems in severely curved root canals: Reciproc and WaveOne. Materials and Methods: Twenty-five mesial ...
Comparison of cyclic fatigue and torsional resistance in reciprocating single-file systems and continuous rotary instrumentation systems
(Nihon Univ, School Dentistry, 2014-12-01)
As compared with continuous rotary systems, reciprocating motion is believed to increase the fatigue resistance of NiTi instruments. We compared the cyclic fatigue and torsional resistance of reciprocating single-file ...
Direct reciprocity in animals: The roles of bonding and affective processes
(Wiley, 2017-04)
The presence of direct reciprocity in animals is a debated topic, because, despite its evolutionary plausibility, it isbelieved to be uncommon. Some authors claim that stable reciprocal exchanges require sophisticated ...
Some properties of classes of real self-reciprocal polynomials
(2016-01-01)
The purpose of this paper is twofold. Firstly we investigate the distribution, simplicity and monotonicity of the zeros around the unit circle and real line of the real self-reciprocal polynomials Rn(λ)(z)=1+λ(z+z2+...+zn-1)+zn, ...
Effectiveness of reciproc and MTwo for removing filling material during root canal retreatment using a digital radiograph system
(2018-01-01)
Objective: To compare the efficacy of Reciproc (reciprocating) and MTwo (rotary) in the filling material removal during endodontic retreatment. Methods: Thirty simulated root canals (plastic blocks) were prepared and filled. ...
Root canal retreatment using reciprocating and continuous rotary nickel-titanium instruments
(2015-01-01)
Objective: The complete filling material removal during endodontic retreatment is a clinical procedure difficult to achieve. The aim of this study was to evaluate the efficacy of reciprocating and continuous rotary ...
Endodontic retreatment: clinical comparison of reciprocating systems versus rotary system in disinfecting root canals
(Springer, 2015-07-01)
Introduction This clinical study was conducted to compare the effectiveness of single-file reciprocating systems and rotary systems in removing endotoxins and cultivable bacteria in endodontic retreatment.Methods Thirty ...
Counterclockwise or clockwise reciprocating motion for oval root canal preparation: a micro-CT analysis
(Wiley-Blackwell, 2018-05-01)
AimTo evaluate oval root canal preparation using one or two instruments in counterclockwise or clockwise reciprocating motion. MethodologyThe radiographic diameter of mandibular human incisors was evaluated, and oval canals ...
Cyclic and Torsional Fatigue Resistance of Reciprocating Single Files Manufactured by Different Nickel-titanium Alloys
(Elsevier B.V., 2017-07-01)
Introduction: The aim of this study was to evaluate the cyclic and torsional fatigue resistance of the following reciprocating single-file systems: ProDesign R 25.06 (Easy Equipamentos Odontologicos, Belo Horizonte, Brazil), ...
