Reciproc® blue

Increased flexibility vs original Reciproc — manufacturer reports ~40% improvement (product page FAQ; exact figure not independently verified)

M-Wire NiTi base with innovative post-machining Blue heat treatment modifies molecular structure for increased cyclic fatigue resistance (per IFU / Scientific Manual)

Can be pre-bent and will maintain shape during use — aids access in difficult cases (per step-by-step card)

S-shaped cross-section with variable taper and non-cutting tip designed specifically for reciprocation (per brochure)

One file shapes entire canal — R25 for most cases, no instrument changes during preparation (per brochure)

R25 can initiate shaping without prior glide path in most cases, but ISO #10 scouting to WL and glide path to ISO #15 may still be needed if scout file must be pre-bent or cannot reach length (per IFU/brochure)

If file does not progress, stop and reassess — do not force; clean flutes, irrigate, recapitulate (per IFU)

Handle is non-autoclavable — safety feature to prevent reuse and metal fatigue from over-use (per brochure)

Files may appear slightly curved from manufacturing — normal, not a defect; no need to straighten (per 2024 IFU Section 4)

For extremely curved canals, use file for single canal only to reduce breakage risk (per 2024 IFU Section 7.2)

Also suitable for retreatment — R25 removes gutta-percha and carrier-based fillings; use brushing motion against lateral walls (per 2024 IFU Section 8.2)
