Root Canal Preparation

This summary breaks preparation into decision steps: case assessment, glide path, shaping, irrigation, and motor usage. Each block is verified with a source link.

Core Principle

The ESE clinical guideline framework defines case assessment, aseptic approach, and re-evaluation during/after treatment as fundamental components of preparation success. [Source]

Chairside Preparation Flow

1

Do not start rotary without glide path

AAE-sourced NiTi recommendations emphasize that establishing a glide path is critical for reducing separation risk. In practice, the goal is to allow the rotary instrument to advance predictably to working length. [Source] [Source]

2

Sequence and rhythm during shaping

Not skipping the file sequence, using light apical pressure, and controlled in-out motion are recommended to limit torsional stress. [Source]

3

Recapitulation + irrigation go together

AAE recommendations emphasize maintaining the glide path through recapitulation; the irrigation literature states that mechanical preparation alone is not sufficient and must be supported by effective irrigation. [Source] [Source]

Endomotor Usage: Quick Notes

  • Skipping the file sequence increases the risk of sudden load buildup.
  • Advance the file gently with short, controlled strokes.
  • After each file, briefly check canal patency (recapitulation).
  • If file deformation (e.g. unwinding) is observed, reassess the decision to reuse.

Note: For final speed/torque settings, always refer to the manufacturer's DFU document for the relevant system.
