Establish glide path first
Use Acrobat Glide Path Files to confirm a reproducible pathway to working length before the shaping sequence begins.
Acrobat 13/.03300 RPM2.0-2.5 NcmTransformX™ ET is intended for clinicians who want an ET-style .04/.06 shaping pathway with a disciplined glide path first. The sequence is simple, but the clinical control comes from respecting each stage.
ET-style workflows can feel familiar and efficient, but shaping files should not be asked to negotiate anatomy that has not been confirmed. Without a reproducible glide path, the file carries more torsional and bending stress.
The clinical priority is to create a stable path, shape with controlled .04 progression, and finish apically only after irrigation and patency checks confirm that the canal remains open.
| Risk factor | Clinical consequence |
|---|---|
| Weak glide pathInitial pathway not confirmed | Higher file stress and reduced control at working length |
| Early apical pressureShaping file pushed before coronal path is prepared | Transportation, ledging, or abrupt canal engagement |
| Poor irrigation rhythmDebris not cleared between stages | Reduced cutting efficiency and increased canal blockage risk |
| Over-enlargementFinal size not matched to anatomy | Unnecessary dentin removal and less conservative shaping |
The ET sequence separates glide path, shaping, and finishing so the file is introduced to each stage with a clearer mechanical task.
Use Acrobat Glide Path Files to confirm a reproducible pathway to working length before the shaping sequence begins.
Acrobat 13/.03300 RPM2.0-2.5 NcmProgress with controlled advancement to working length. Irrigate, recapitulate, and re-irrigate before moving to the next file.
ET 20/.04350 RPM3.0 NcmUse ET 25/.04 or the appropriate finishing size when anatomy supports it. The final file should complete the preparation, not force it.
ET 25/.04Separates initial canal negotiation from shaping, reducing file stress and improving clinician confidence.
Supports a familiar ET-style sequence while maintaining a conservative, staged preparation philosophy.
Tip geometry supports centred progression and reduced risk of ledging or apical transportation.
Use the ET technique when the clinician wants a familiar .04 shaping sequence with strong emphasis on controlled glide path, irrigation rhythm, and adaptable apical finishing.
