# RC Blue™

> Blue-Treated Reciprocating Sequence

- **Manufacturer:** Perfect Dental (Shenzhen Perfect Medical Instruments)
- **Motion:** Reciprocating
- **Alloy:** Blue Heat-Treated NiTi
- **Key feature:** Three-instrument reciprocating set (R25 25/.08, R40 40/.06, R50 50/.05) finished with a Blue post-machining heat treatment; same dimensions and motor parameters as RC (per IFU spec table)

## Protocol

### Glide Path

1. **Manual Glide Path** — Establish a manual glide path with an ISO 010 K-file to working length, watch-winding gently and irrigating with sodium hypochlorite (per IFU step-by-step).

### Shaping

1. **Reciprocating Shaping with Blue-Treated Files** — Select the file based on canal size. Flood the canal with NaOCl, run the file in a reciprocating motor, and advance with slight 2–3 mm thrusts. Reach more than 2/3 of working length one or more times. Each cutting motion can be advanced easily; one step usually completes after three in–out passes (per IFU step-by-step). _(File: R25 / R40 / R50 · Reciprocating 250-360 rpm · 2.0-3.0 N·cm · Reciprocating)_
   - Blue post-machining heat treatment is described as improving flexibility and cyclic fatigue resistance vs conventional NiTi (per family marketing — exact figure not independently verified)
   - After each step, rinse the canal and use an ISO 010 C-type file to confirm patency (per IFU step-by-step)
   - ⚠ Do not force the file — clean, irrigate, and recapitulate with a hand file if progress stops (per IFU precautions)

### Finishing

1. **Confirm Working Length** — Verify working length and canal condition with an ISO 010 file at each gauge step before obturation (per IFU step-by-step).

## Clinical Tips

- IFU title "INSTRUCTION FOR USE — RC/RC GOLD/RC BLUE" is shared across all three metallurgy tiers; the IFU body text does not differentiate Blue-specific protocol parameters (per IFU)
- RC Blue uses the same published spec table dimensions and motor parameters as RC; the Blue post-machining heat treatment is a brand/packaging-level distinction not detailed in the IFU body
- Blue heat-treatment flexibility / pre-bendability / cyclic-fatigue claims come from product branding rather than the IFU text — exact figures are not independently verified
- IFU step 8 explicitly covers retreatment: "During the retreatment process, complete the cutting action using the same action as step ③" (per IFU step-by-step)
- Per IFU precautions, avoid continuous-rotation reaming on extremely curved canals; small-angle motions (filing, watch-winding, balanced force) are recommended for high-curvature cases (per IFU precautions)

## Warnings

- Single-use; discard after each canal (per IFU section 3)
- Do not autoclave above 200 °C including drying phase (per IFU sterilization section)
- Do not fully immerse in NaOCl; only the working part may contact a max 5% NaCl solution for up to 5 minutes (per IFU section 4)
- Inspect each file for distortion, unwinding, corrosion, or damaged edges before use (per IFU section 4)
- Use minimal apical pressure; never force the file (per IFU section 4)
- Contraindicated in patients with nickel allergy (per IFU section 1)

## Contraindications

- patients with known nickel allergy (per IFU)

## Best for

- blue-treated reciprocating workflow
