Clinical Tips
- Slider-first glide path: Slider can often be used without prior K-file (63% of cases per Dentsply user study). If Slider does not easily reach terminus, use a small SS hand file first, establish WL/patency, then retry Slider (per IFU)
- Only one Shaper needed for coronal 2/3 enlargement
- Triple heat treatment: M-Wire (Slider), Gold (Shaper/F1-F3), Blue (FX/FXL)
- Blue heat treatment on FX/FXL: dedicated to larger and straighter canals
- Manufacturer reports 32% faster glide path and shaping vs ProGlider + PTG up to F2 (product page bench data, not independent clinical validation)
- Manufacturer reports F1: +13% flexibility, +75% cyclic fatigue resistance vs PTG F1 (fact file bench data)
- Manufacturer reports F2: +30% flexibility, +30% cyclic fatigue resistance vs PTG F2 (fact file bench data)
- Manufacturer reports higher unwinding resistance vs previous generations (fact file bench data; Diaconu 2024 supports improved cyclic fatigue vs PTG F2 in vitro, PMID 38667542)
- Use outward brushing motion away from furcation in irregular canals, or light inward pecking to advance
- Dedicated hand-use version available for all PTU files with same technical features
- Compatible with ProTaper Ultimate Conform Fit GP points and absorbent points
- For extremely curved canals: use single canal per file and consider manual files in apical region (per IFU)
Warnings
- Single-use only — do not reprocess or reuse
- Toxic or allergic reactions caused by processing residues are a risk listed in the IFU — follow the IFU strictly to minimize it (per IFU)
- Discard if any unwinding, straightening, or stretching is observed
- Do not fully immerse in NaOCl — only working part in max 5% concentration (per IFU)
- FX and FXL are for larger and straighter canals only (per IFU)
- Inspect cutting flutes upon removal from every canal
- Always reconfirm working length after shaping, especially in curved canals
- In severe curvatures: machine-driven use may not be appropriate in abrupt apical curves — use pre-curved hand files apically (per IFU)
