Cyclic Fatigue Comparison of TruNatomy, Twisted File, and ProTaper Next Rotary Systems

Comparison of the centering ability of the ProTaper Universal, ProFile and Twisted File Rotary Systems

Aim: To determine the centering ability of Twisted FileTM rotary system compared with ProTaper UniversalTM and ProFileTM rotary systems by evaluating preand postoperative cross-sectional images of the apical root canals third. Methods: Thirty mesiobuccal canals of human mandibular first molars were divided into three groups with 10 root canals each according to the instrument used: group 1, Pro...

Cyclic fatigue resistance of ProTaper Universal, Twisted File Adaptive, Reciproc and WaveOne systems

Comparison of cleaning efficiency and deformation characteristics of Twisted File and ProTaper rotary instruments

OBJECTIVE The objective of the following study is to compare the cleaning efficiency and deformation characteristics of Twisted File (TF) and ProTaper (PT) nickel-titanium rotary instruments in root canal preparation. MATERIALS AND METHODS A total of 52 canals from 26 extracted maxillary first molars were randomly assigned into two groups of each including 13 mesiobuccal and 12 distobuccal (D...

comparison of cyclic fatigue resistance of five nickel titanium rotary file systems with different manufacturing techniques

objectives: the purpose of this study was to evaluate the resistance to fatigue failure of five different nickel-titanium rotary files in three different curved trajectories. materials and methods: a total of 150 neoniti a1, race 25.06, mtwo 25.06, twisted file 25.06 and protaper next x2 files with the tip size of 25 were tested (n=30 for each group). three groove types simulating curved canals...

Apical extrusion of debris using ProTaper Universal and ProTaper Next rotary systems.

AIM To assess and compare the amount of extruded debris after canal preparation using ProTaper Universal and ProTaper Next files. METHODOLOGY Forty extracted mandibular premolars with single canals and of similar lengths were instrumented using the ProTaper Universal F3 or the ProTaper Next X3. The extruded debris during instrumentation was collected into pre-weighed Eppendorf tubes. The tube...
