Root surface strain during canal shaping and its influence on apical microcrack development: a preliminary investigation.

International endodontic journal·2014

Area of Science:

  • Endodontics
  • Dental Materials Science

Background:

  • Root canal preparation traditionally involves manual instrumentation, which can be time-consuming and operator-dependent.
  • Nickel-titanium rotary files offer improved flexibility and cutting efficiency but require precise control to prevent procedural errors.
  • Existing engine-driven systems may lack real-time feedback on file position and applied torque, increasing risks.

Purpose of the Study:

  • To introduce and evaluate a novel cordless, engine-driven root canal preparation system with integrated electronic monitoring.
  • To assess the safety and efficiency features of the new system, including auto-apical-reverse and auto-torque-reverse mechanisms.

Main Methods:

  • A new cordless, engine-driven system (Root ZX) was developed, incorporating an electronic apex locator within the handpiece.

  • The system utilizes nickel-titanium files rotating at 240-280 rpm, powered by a rechargeable battery offering over 40 minutes of use.
  • Automatic file rotation reversal functions (auto-apical-reverse and auto-torque-reverse) were integrated to enhance safety.

    • Main Results:

    • The Root ZX system electronically monitors file tip location and applied torque in real-time during root canal instrumentation.
    • The integrated apex locator aids in precise measurement of canal length.
    • The auto-apical-reverse and auto-torque-reverse mechanisms are designed to prevent file separation and over-instrumentation.

    Conclusions:

    • The developed cordless engine-driven system offers advanced safety features for root canal preparation.
    • Real-time electronic monitoring and automatic reversal mechanisms promise a safer engine-driven approach using nickel-titanium files.
    • This technology has the potential to improve procedural outcomes and reduce complications in endodontic treatment.
