NIC® V Blue
Three-size single-file reciprocating system (R25/R40/R50, S-shaped, regressive taper) on a 150°/30° alternating program in pre-bendable MaxTech 6.0 blue wire with IFU-defined apical gauging

Clinical Tips
Kinematics per the manufacturer's fact sheet (2026-08-12): alternating 150° counter-clockwise / 30° clockwise — the IFU draft itself printed no angles and defers to the motor's authorized reciprocating program, which it explicitly forbids substituting with a continuous-rotation setting
R25 is the primary size for most routine canals; R40 and R50 are selected only when anatomy and apical gauging indicate a larger preparation (IFU)
Built-in gauging scheme: 030 after R25, 050 after R40, 060 after R50 — snug at length signals completion (IFU)
MaxTech 6.0 blue heat treatment allows the file to be gently pre-bent to improve access, and the manufacturer positions the tier for curvature up to ~30° — manufacturer claims, not independently verified
S-shaped cross-section with two cutting edges and a regressive taper intended to limit unnecessary coronal dentin removal (manufacturer)
NIC's own cross-reference table maps the V-Series to Reciproc / Reciproc Blue users, with matching R25/R40/R50 naming — a manufacturer-claimed correspondence, not independently verified
The IFU conditionally mentions retreatment assistance (removing gutta-percha) 'when permitted by the current NIC labelling' — treat this as unconfirmed until NIC publishes explicit retreatment instructions
Do not fully immerse the files in sodium hypochlorite solution (IFU)
Supplied 6 instruments per pack; 21/25/31 mm lengths; maximum flute diameter 1.2 mm (fact sheet)
Two sibling lines appear on the manufacturer's fact sheet but are not listed here: an untreated V File (MaxTech 1.0, same R25/R40/R50 sizes, positioned as the Reciproc alternative) and a blue V Mini series with a 0.8 mm flute diameter (R20 20/.08 through 45/.05)
Specifications on this page come from the manufacturer's consolidated fact sheet (2026-08-12, the controlling source), IFU draft (2026), and 2025 catalog; no independent peer-reviewed performance data exists for this system (PubMed, 2026-08-11)
Warnings
- Single-use only per the manufacturer's IFU — reuse may increase the risk of cross-contamination, loss of cutting efficiency, or file separation
- Supplied non-sterile in this version: sterilize before first clinical use (steam autoclave 134 °C, 18 min holding time per the IFU) and discard after the procedure
- Use only in the motor's authorized reciprocating mode — the IFU directs never to use continuous rotation with these files
- Do not use a file from a damaged package, or any instrument showing deformation, unwinding, corrosion, fracture, or wear (IFU)
- Use very light apical pressure with pecks of about 3 mm or less; forcing the file may cause separation, ledging, transportation, or perforation (IFU)
- Contains nickel — the IFU contraindicates use in patients with known nickel/NiTi allergic sensitivity
- The IFU contraindicates mechanical use in canals with severe, sudden apical curvatures, complex canal divisions, calcified anatomy, or anatomy where safe passive file progression cannot be achieved
