“…Three articles on molars were selected for this review. In these articles, the Reciproc system showed lower apical extrusion of debris [ 49 , 50 ]; however, in the study by Kuştarcı et al , there was no statistically significant difference between the Reciproc and TFA systems evaluated in premolars [ 51 ].…”

Advances in endodontics have enabled the evolution of file manufacturing processes, improving performance beyond that of conventional files. In the present study, systems manufactured using state of the art methods and possessing special properties related to NiTi alloys (i.e., CM-Wire, M-Wire and R-Phase) were selected. The aim of this review was to provide a detailed analysis of the literature about the relationship between recently introduced NiTi files with different movement kinematics and shaping ability, apical extrusion of debris and dentin defects in root canal preparations. From March 2016 to January 2017, electronic searches were conducted in the PubMed and SCOPUS databases for articles published since January 2010. In vitro studies performed on extracted human teeth and published in English were considered for this review. Based on the inclusion criteria, 71 papers were selected for the analysis of full-text copies. Specific analysis was performed on 45 articles describing the effects of reciprocating, continuous and adaptive movements on the WaveOne Gold, Reciproc, HyFlex CM and Twisted File Adaptive systems. A wide range of testing conditions and methodologies have been used to compare the systems. Due the controversies among the results, the characteristics of the files used, such as their design and alloys, appear to be inconsistent to determine the best approach.

“…Other studies have demonstrated a change in the surface of rotary instruments after use ( 8 ). Although many previous studies have investigated various aspects of the ProTaper Next™ and ProTaper® Universal files, which include canal shaping ability ( 9 ), cyclic fatigue resistance ( 10 ), amount of debris extruded ( 11 ) etc., no studies have investigated how the surface and the alloy features would affect instrument fracture. Hence, the aim of this study was to analyze surface irregularities of these two rotary files before use and after instrumentation in curved canals in extracted human teeth.…”

BackgroundMany new rotary files systems have been introduced, however, limited research has been conducted related to the surface irregularities of these files and if these have any effects on the files themselves. Hence, the aim of the present study was to analyze surface irregularities of the ProTaper® Universal rotary files (PTU) and the ProTaper Next™ rotary files (PTN) before and after instrumentation in curved canals. The main objective was to investigate the nature of these irregularities and how they might influence the use and fracture of rotary files during root-canal treatments.Material and MethodsThe files were examined pre-operatively using a stereomicroscope and scanning electron microscopy(SEM) to analyze surface imperfections and the presence of particles. Mesial roots of forty extracted mandibular molars were selected. Each instrument was used to prepare one of the mesial canals. The files were then rinsed with alcohol, and autoclaved and analyzed again.ResultsOf the 80 files used in this study, five files fractured, five files unwound and seven files were curved or bent and they all belonged to the PTU group. Irregularities and debris could be visualized with the SEM on both unused PTU and PTN files. Most of the debris was found associated with deeper milling grooves and defects on the surface of the metal. Surface analysis of the files that were used and sterilized were performed and the SEM images demonstrated organic debris, metal flash, and crack formation and initiation of fractures for both file types. All files showed machining grooves, metal flash, debris, and defects on cutting edges.ConclusionsThese irregularities appear to be critical in the accumulation of debris and initiation of fatigue and crack propagation within the NiTi alloy. The accumulation of debris could be a concern due to the potential exchange of organic debris between patients. Key words:ProTaper® Universal, ProTaper Next™, surface characteristics, SEM.

“…5 According to the literature, all instrumentation techniques exhibit some degree of apical extrusion of debris during treatment, however the amount of extruded product will vary depending on the used instrument. 12, 16,18,20 Therefore, the present study aimed to evaluate which rotary instrumentation technique leads to the greatest amount of extruded apical debris, using two different systems instrumentation (Protaper Universal and Protaper Next).…”

Objective: the purpose of this literature review was to evaluate apical debris extrusion after root canal preparation with Protaper Universal and Protaper Next Rotary systems. Material and Methods: the question that supported the collection of scientific evidence for the present study was: Which rotary system presents the best performance regarding the apical extrusion of debris: Protaper Universal or Protaper Next? From the online search databases, a bibliographic research was carried out covering original research studies, using as descriptors: Apical extrusion debris, Protaper Universal and Protaper Next. Articles had to meet the following inclusion criteria: should have been published in the English language from 2014 to 2017 and should compare both mentioned rotary files systems regarding apical extrusion of debris in the same study. Ninety-six articles were found after research and six were included for this integrative review. Results: six studies remained included after the inclusion criteria analysis. Of these, 50% were published in 2016, 16.6% in 2015 and and 33% in 2014. Weight establishment of the extruded material was the methodology used in all studies to evaluate the performance of the files By analyzing the amount of apically extruded material, it was found that the Protaper Universal system extruded more quantity than the Protaper Next system. Conclusion: it was concluded that, although there is no system capable of performing the instrumentation without promoting apical extrusion, the Protaper Next rotary files system presented better performance when compared to the Protaper Universal files system, regarding the apical debris extrusion.

Abstract: All systems caused apical debris extrusion during curved canal preparations. However, the PTG, PTN, and RECIPROC systems resulted in significantly less debris extrusion than the PTU system.
