Comparison of the Shaping Ability of RaCe and FlexMaster Rotary Nickel-Titanium Systems in Simulated Canals

Root Canal Anatomy Preservation of WaveOne Reciprocating Files with or without Glide Path

“…Even though they do not represent the anatomic variability of a human root canal system, simulated resin canals have been widely used to point out differences in performance of instruments under standardized experimental conditions (18). Studies suggested that the analysis of modifications in canal curvature after instrumentation is a reliable method to evaluate the tendency of a shaping technique to maintain the original canal anatomy or to straighten the curves (19).…”

Use of Nickel-Titanium Rotary PathFile to Create the Glide Path: Comparison With Manual Preflaring in Simulated Root Canals

“…Furthermore, analysis of modifications in canal curvature after instrumentation has been widely used to evaluate the tendency of a technique, or of the mechanical properties of an instrument, to maintain the original canal anatomy or to straighten the curves (20) as well as to evaluate the performances of operators with different levels of expertise (21).…”

Comparison among Manual Instruments and PathFile and Mtwo Rotary Instruments to Create a Glide Path in the Root Canal Preparation of Curved Canals

“…This difficulty has been correlated with the observation of performance differences between different instrument systems (22)(23)(24). Furthermore, the evaluation of the changes in canal curvatures after instrumentation has been widely used to assess the tendency of a given technique or of the mechanical properties of a certain instrument to maintain the original anatomy of the canal or rectify its curvatures (22,25).…”
