Clinical Tips
- All ESX files operate at 500-600 RPM with a torque setting of 1.5-2.3 Ncm (per brochure). Any continuous-rotation endodontic motor with torque control may be used.
- The two-file concept (Expeditor + Finishing file) is designed for minimally invasive canal preparation that preserves coronal tooth structure.
- The patented ACP (Alternating Contact Point) design features an asymmetrical flute that alternates between zero to three points of engagement, which may help move debris coronally (per brochure).
- The patented Booster Tip features 6 cutting edges that transition to a reamer design, which may help the file follow the canal shape with reduced risk of ledging (per brochure).
- Electropolished surface finish may improve resistance to cyclic and torsional fatigue compared to non-electropolished instruments (per brochure).
- The Expeditor's engagement level serves as a diagnostic tool to select the appropriate finishing file size for each individual canal.
- Single-use, sterile instruments — provided in individually perforated sterile blister packs (per brochure).
- The ESX system is designed to synchronize with EndoSequence BC obturation and EndoSequence Fiber Post systems (per brochure).
Warnings
- Single-use, sterile instruments — do not reprocess or reuse
- Use at 500-600 RPM with 1.5-2.3 Ncm torque (per brochure)
- Use a light touch — do not apply heavy apical pressure
- Use the single stroke and clean technique (per brochure)
- Use only in clockwise continuous rotation
- If the Expeditor meets significant resistance, use scouting files or orifice opener first (per brochure)
- Contains nickel-titanium — do not use on patients with known nickel allergy
Obturation Techniques
Single cone, warm vertical, carrier-based & lateral compaction

Frequently Asked Questions
What alloy is ESX made from?
What alloy is ESX made from?
Answer
ESX® is manufactured from Electropolished NiTi with conventional heat treatment.
How many files are in the ESX sequence?
How many files are in the ESX sequence?
Answer
The ESX® system includes 8 files: Expeditor, Small (#25/.04), Medium (#35/.04), Large (#45/.04), Extra-Large (#55/.04), Orifice Opener (#20/.08), Scouting File (#15/.02), Scouting File (#15/.04).
What is the ESX file sequence?
What is the ESX file sequence?
Answer
ESX® is used in this order: Orifice Opener (#20/.08) → Scouting File (#15/.02) → Scouting File (#15/.04) → Expeditor → Small (#25/.04) → Medium (#35/.04) → Large (#45/.04) → Extra-Large (#55/.04).
- Per-file speed, torque and technique are in the protocol section above.
What motion type does ESX use?
What motion type does ESX use?
Answer
ESX® uses continuous rotation motion.
What cases is ESX best for?
What cases is ESX best for?
Answer
ESX® is best suited for: minimally invasive two-file canal preparation, conservative coronal tooth structure preservation, cases where adaptive finishing file size selection is preferred.
What speed and torque settings are recommended for ESX?
What speed and torque settings are recommended for ESX?
Answer
Recommended settings: 500-600 RPM and 1.5-2.3 Ncm across the file sequence (refer to official DFU for full per-file parameters).
