Reciprocating root canal preparation with nickel-titanium files is faster than continuous rotation. While effective, this technique risks file distortion and fracture, requiring careful consideration before clinical use.

Area of Science:

  • Endodontics
  • Dental Materials Science

Background:

  • Root canal preparation aims to clean and shape the root canal system.
  • Conventional nickel-titanium rotary files are widely used, but preparation time and file safety remain concerns.

Purpose of the Study:

  • To evaluate the efficacy and safety of a reciprocating movement technique using conventional nickel-titanium rotary files for root canal preparation.
  • To compare preparation time and canal centering ability between reciprocating and continuous rotation techniques.

Main Methods:

  • Forty-four simulated root canals in resin blocks were prepared using either continuous rotation or reciprocating movements with ProFile and RaCe nickel-titanium files.
  • Preparation time and centering ratio were assessed.
  • File morphology was examined using scanning electron microscopy (SEM) to detect distortion.

Main Results:

  • Reciprocating movement significantly reduced preparation time compared to continuous rotation.
  • No significant difference in centering ratio was observed between the techniques.
  • Files used with the reciprocating technique showed considerable torsional distortion, unlike those used with continuous rotation.

Conclusions:

  • Reciprocating instrumentation with conventional nickel-titanium rotary files offers comparable root canal shaping efficacy with reduced preparation time.
  • The risk of torsional distortion and potential fracture necessitates caution for clinical application of this technique.
