Clinical Tips
- All files use 250-400 RPM (per IFU); 300 RPM is a common working speed
- 2-file core sequence (TS1+TS2) is sufficient for the majority of canals
- 3-wave progressive pecking technique: 3 gentle up-and-down movements per pass
- Circumferential brushing at resistance eliminates primary constraints
- T.Wire = post-grinding heat treatment providing improved cyclic fatigue resistance vs untreated NiTi
- Asymmetrical triple helix (2 main + 1 secondary cutting edge) reduces screw-in effect and improves debris removal
- Maximum 5 canals per instrument if not visually damaged (IFU recommendation)
- Compatible One G / One Flare glide path ecosystem available
- Matching 2Shape gutta-percha and paper points available for TS2, F35, F40 (per 2026 flyer)
- Compatible with all standard endodontic motors (continuous rotation)
Warnings
- Contains nickel and titanium — do not use on patients with nickel or titanium allergy
- Do not use for retreatment cases (IFU contraindication)
- Check instrument before each use and between canals for signs of damage
- Discard immediately if damaged, deformed, or unwound
- Maximum 5 canals per instrument recommended — do not exceed
- Use continuous rotation at recommended speed (250-400 RPM per IFU) — never reciprocating
- Always establish glide path before using rotary files
- Use rubber dam during treatment
- Do not force files apically — use gentle progressive movement
