## Protocol

### Glide Path

1. **Open Crown and Scout** — Perform conventional open-crown access and locate the canal orifice. Scout and dredge the canal with ISO 010 or ISO 015 K-files (per brochure step 1).
2. **Coronal Opening with B0** — Use B0 (17/.10 starter) to open the upper section of the canal and establish a vertical channel (per brochure step 2). _(File: B0 17/.10 · 425-500 rpm · 2.5 N·cm)_

### Shaping

1. **Determine Working Length** — Confirm the working length electronically and radiographically before introducing the shaping files (per brochure step 3).
2. **Shape Successively with B1 → B2 → B3** — Use the S-Blue work files successively into the canal to working length: B1 (20/.04) for small canals, B2 (25/.06) for standard, B3 (35/.04) for wider canals (per brochure step 4 and image set). _(File: B1 → B2 → B3 · 425-500 rpm · 2.5 N·cm)_
   - Uniform speed/torque across the set means no per-file motor adjustments — intended for predictable entry-level use (per brochure)
   - Heat-activated alloy permits pre-bending; brand cites 3–5× improved fracture resistance vs conventional NiTi (per brochure marketing claim — not independently verified)
   - Circular triangle cross-section is described as supporting balanced cutting and reduced screw-in tendency (per brochure)

### Finishing

1. **Confirm Final Apical Size** — Verify the final apical preparation with a matching hand file and irrigate before obturation.

## Clinical Tips

- Brochure spec table: B0(starter) 17/.10, B1 20/.04, B2 25/.06, B3 35/.04 — all at 425–500 rpm and 2.5 N·cm (per brochure)
- Uniform 425–500 rpm / 2.5 N·cm across all four files — does not need repeated motor adjustment (per brochure Design Concept)
- Heat-activated alloy is pre-bendable; brand reports 3–5× cyclic fatigue improvement vs conventional NiTi (per brochure marketing claim — not independently verified)
- Marketed as entry-level — sized for general posterior shaping rather than premium-tier protocols (per brochure positioning)
- File lengths are NOT specified in the brochure spec table — the 21/25/31 mm range listed here is inferred from the Perfect Dental family default and should be verified against the actual product packaging before clinical use
- Brochure body uses the term "heat-activated material" without specifically naming "Blue" as the heat-treatment process; product name S-Blue suggests Blue heat treatment but the brochure does not explicitly confirm it

## Warnings

- S-Blue brochure has no stand-alone warnings/precautions section; the warnings below are derived from the Perfect Dental IFU family pattern (RC, TS4, PX Wave, TF4, TG6) and are attributed accordingly
- Single-use; discard after each canal (per Perfect Dental IFU family precautions)
- Do not autoclave above 200 °C including drying phase (per Perfect Dental IFU family precautions)
- Do not fully immerse in NaOCl; only the working part may contact a max 5% NaCl solution for up to 5 minutes (per Perfect Dental IFU family precautions)
- Inspect each file before use for distortion, unwinding, corrosion, or damaged edges (per Perfect Dental IFU family precautions)
- Use minimal apical pressure; never force the file (per Perfect Dental IFU family precautions)
- Contraindicated in patients with nickel allergy (per Perfect Dental IFU family precautions)

## Contraindications

- patients with known nickel allergy (per IFU)

## FAQ

**What alloy is S-Blue made from?**

S-Blue™ is manufactured from Blue Heat-Activated NiTi.

**How many files are in the S-Blue sequence?**

The S-Blue™ system includes 4 files: B0 (starter), B1, B2, B3.

**What is the S-Blue file sequence?**

S-Blue™ is used in this order: B0 (starter) → B1 → B2 → B3. Per-file speed, torque and technique are in the protocol section above.

**What motion type does S-Blue use?**

S-Blue™ uses continuous rotation motion.

**What cases is S-Blue best for?**

S-Blue™ is best suited for: entry-level heat-treated rotary sequence, general posterior shaping with predictable motor settings, pre-bendable files for moderate access challenges.

**What speed and torque settings are recommended for S-Blue?**

Recommended settings: 425-500 RPM and 2.5 Ncm across the file sequence (refer to official DFU for full per-file parameters).
