The Self-Adjusting File Optimizes Debridement Quality in Oval-Shaped Root Canals

Journal of Endodontics, 2011
Oval-shaped canals represent a challenge for rotary nickel-titanium (NiTi) files because buccal and/or lingual recesses are commonly left uninstrumented. The aim of the present study was to evaluate the debridement quality of the Self-Adjusting File (SAF) system in oval canals and compare it with the debridement achieved by a commonly used NiTi rotary ...

Assessment of Apically Extruded Debris Produced by the Self-Adjusting File System

Journal of Endodontics, 2014
This study was designed to quantitatively evaluate the amount of apically extruded debris by the Self-Adjusting-File system (SAF; ReDent-Nova, Ra'anana, Israel). Hand and rotary instruments were used as references for comparison.Sixty mesial roots of mandibular molars were randomly assigned to 3 groups (n = 20).

Fracture Strength of Roots Instrumented With Self-Adjusting File and the ProTaper Rotary Systems

Journal of Endodontics, 2014
The purpose of this study was to evaluate the fracture strength of roots instrumented with the Self-Adjusting File (SAF; ReDent-Nova, Ra'anana, Israel) and the ProTaper system (Dentsply Maillefer, Ballaigues, Switzerland) and filled with the cold lateral compaction technique.In total, 50 mandibular premolar teeth were sectioned at or below the ...

Eight Months of Clinical Experience with the Self-Adjusting File System

Journal of Endodontics, 2011
The Self-Adjusting File (SAF) system (ReDent-Nova, Ra'anana, Israel) has been recently introduced for the simultaneous instrumentation and irrigation of root canals. The SAF is claimed to adapt itself three dimensionally to the root canal, including its cross-section.

Stress Generation during Self-Adjusting File Movement: Minimally Invasive Instrumentation

Journal of Endodontics, 2013
Although nickel-titanium (NiTi) rotary instruments may produce a well- tapered root canal with a low tendency of aberrations, these are generally perceived to have a high fracture risk during use and may produce significant forces on root dentin during instrumentation, which may induce a dentinal defect or crack in the apical part of the root.

Time-Dependent Antibacterial Effects of the Self-Adjusting File Used With Two Sodium Hypochlorite Concentrations

Journal of Endodontics, 2011
This in vitro study evaluated the time-dependent ability of the self-adjusting file (SAF) used with either of two NaOCl concentrations to reduce bacterial populations in long oval root canals.Oval-shaped canals from extracted teeth were infected with Enterococcus faecalis for 30 days and subjected to preparation with the SAF system using continuous ...

In Vitro Canal and Isthmus Debris Removal of the Self-Adjusting File, K3, and WaveOne Files in the Mesial Root of Human Mandibular Molars

Journal of Endodontics, 2012
The purpose of this study was to compare the effectiveness of debris removal between the Self-Adjusting File (SAF), WaveOne, and K3 file systems in the mesial roots of mandibular molars. In addition, the SAF was tested as a potential adjunct after instrumentation with other systems.The mesial roots of 30 extracted mandibular molars were mounted in ...

Continuous Instrumentation and Irrigation: The Self-Adjusting File (SAF) System

2015
The recently introduced self-adjusting file (SAF) system is the first of its kind, performing continuous and simultaneous instrumentation and irrigation. As an instrumentation device it adapts itself to the shape of the canal, including its cross section, as opposed to most rotary file systems that machine the canal to the shape of the file.

Self-Adjusting File Cleaning-Shaping-Irrigation System Improves Root-Filling Bond Strength

Journal of Endodontics, 2013
The aim of the present study was to assess the bond strength of root fillings in oval-shaped canals prepared with the self-adjusting file (SAF) system.A careful specimen selection resulted in 2 equal groups, each consisting of 12 extracted mandibular canines with oval canals that had vital pulps before extraction.
