WaveOne Gold, ProTaper Reciproc Blue, Next, and files were selected to compare the phase transformation behaviors mechanical properties of nickel-titanium (NiTi) rotary after gold heat blue treatments. The reverse finishing point temperatures Next higher than those other two instruments investigated. At a deflection 0.5 mm, loads significantly varied except for Gold. 3.0 Blue Gold compared ProT...

In recent years, thanks to the rapid advancement of science and technology a better understanding anatomy root canal system, many new endodontic instruments materials have been introduced with desire minimize complications in process preparing canal, help cleaning shaping complete well. It is noteworthy that emergence files made Nickel-Titanium alloy (NiTi files), which, according recommendatio...

Background and aims: Widely application of rotary files for endo treatment would force us to obtain an accurate understanding about the characteristics drawbacks these instruments. Therefore in this study, effects immersion NiTi M2 file deconex sodium hypochlorite solution on cyclic fatigue resistance was investigated Material methods: In exprimental 45 NITI were divided three groups I) control...

Background. The aim of this study was to compare the dentinal defects caused by Reciproc, TF Adaptive and ProTaper Next NiTi rotary file systems during the retreatment procedure. Methods. A total of 150 mandibular incisors with straight and single root canals were included in the present study. All the root canals were prepared up to an apical diameter 0.40 mm using stainless steel files. Thirt...

introduction: this study was carried out to compare the capability of k-files with mtwo rotary file in terms of negotiation as well as depth of penetration in second mesiobuccal (mb2) canal of maxillary first molar. materials and methods: a total of 32 mb2 canal of maxillary first molars having different root curvatures (not more than 30 degree) and root lengths were selected and then detected ...

Background. This study compared the cyclic fatigue resistance, bending resistance and cross-sectional areas of Reciproc Blue (RPC Blue), WaveOne Gold (WOG), and Genius File (GF) NiTi rotary systems. Methods. Forty RPC Blue R25 (25/.08), 40 WOG Primary (25/.07) and 40 GF (25/.04) files were used in the present study. Flexibility of the files was determined by 45° bending test. The instruments we...

INTRODUCTION Single use of endodontic nickel-titanium (NiTi) instruments has been recommended to reduce instrument fatigue and the possibility of cross-contamination. The purpose of this study was to evaluate the defects of three NiTi rotary systems (ProFile series 29 [Dentsply Tulsa Dental Products, Tulsa, OK], ProFile [Dentsply Tulsa Dental Products], and ProTaper [Dentsply Maillefer, Ballaig...

introduction: the preparation of the root canal space includes debridement, shaping and apical preparation. these procedures are challenging and constitute. the recent introduction of automated techniques for canal preparation has created considerable interest. the aim of this study was to test shaping ability of one hand instrumentation (passive step-back technique) and new rotary niti system ...

The last decade has been witness to phenomenal growth in endodontic technology. The introduction of these new technologies has resulted in endodontics becoming easier, faster and most importantly, better. Principal among these is Nickel Titanium (NiTi) rotary instrumentation that results in consistent, predictable, and reproducible shaping. The purpose of this article is to review the design fe...
