Clinical Tips
- High-purity NiTi alloy is described as having low carbon and oxygen impurities (per brochure marketing claim — not independently verified)
- T-Flex is positioned for curved anatomy; brand claims suitability across simple and complex root canals (per brochure)
- Low resilience is cited as reducing ledging, central deviation, and canal transportation (per brochure)
Warnings
- Single-canal use (a new file, discarded after the canal is treated) is advised when shaping extremely curved canals (per Perfect Dental IFU family precautions — T-Flex brochure has no dedicated IFU section)
- Do not autoclave above 200 °C including drying phase (per Perfect Dental IFU family precautions — T-Flex brochure has no dedicated IFU section)
- Do not fully immerse in NaOCl; only the working part may contact a max 5% NaOCl solution for up to 5 minutes (per Perfect Dental IFU family precautions — T-Flex brochure has no dedicated IFU section)
- Use minimal apical pressure; never force the file (per Perfect Dental IFU family precautions — T-Flex brochure has no dedicated IFU section)
- Inspect each file for distortion, unwinding, corrosion, or damaged edges before use (per Perfect Dental IFU family precautions — T-Flex brochure has no dedicated IFU section)
- Contraindicated in patients with nickel allergy (per Perfect Dental IFU family precautions — T-Flex brochure has no dedicated IFU section)
