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

Establish glide path before rotary

AAE-sourced NiTi recommendations emphasize that establishing a glide path can help reduce 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

Using instruments in sequence, light apical pressure, and an in-and-out pecking motion are recommended to reduce file stress and separation risk. [Source]

3

Recapitulation + irrigation go together

AAE recommendations emphasize maintaining the glide path through recapitulation; the irrigation literature states that mechanical preparation alone may not be sufficient and generally benefits from 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, refer to the manufacturer's DFU document for the relevant system.
