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-canal use (a new file, discarded after the canal is treated) is advised when shaping extremely curved canals (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% NaOCl 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)
