The new Flexogate endodontic instrument showed significant canal transportation, particularly in the apical outer curve, when used in simulated curved root canals. Further research is needed to assess its clinical effectiveness.

Area of Science:

  • Endodontics
  • Dental instrument design
  • Root canal anatomy

Background:

  • Curved root canals present challenges in endodontic treatment.
  • Endodontic instrument design modifications aim to improve canal preparation.
  • The Flexogate instrument was developed to address apical preparation issues.

Purpose of the Study:

  • To evaluate the cutting pattern of Flexogate instruments.
  • To assess canal transportation in curved canals using Flexogates.
  • To analyze the behavior of Flexogates in simulated curved root canals.

Main Methods:

  • Simulated curved root canals (45 degrees) in plastic blocks were used.
  • Four operators prepared the canals using Flexogate instruments.
  • Image analysis quantified canal shape changes before and after instrumentation.

Main Results:

  • Flexogate instruments did not maintain centering within the simulated canal.
  • Maximum canal transportation occurred in the apical third of the outer curve.
  • Minimal to no transportation was observed in the coronal and middle thirds.

Conclusions:

  • Flexogates exhibit significant canal transportation, especially apically.
  • The clinical impact of this transportation requires further investigation.
  • Coronal preflaring and in-vivo studies are recommended.
