## Protocol

### Glide Path

1. **Establish Glide Path** — Between each rotary V-Blue file, recapitulate with a #10 or #15 hand file to maintain glide path and aid irrigation with sodium hypochlorite to the canal terminus (per brochure protocol).
   - Recapitulation between rotary files maintains apical patency (per brochure)
   - Brand notes files may appear slightly curved after wire processing; finger-straightening is not required (per brochure)

### Shaping

1. **Crown-Down for Small Canals** — Initiate crown-down cleaning and shaping. In small canals, start with a 30/.04 rotary file to resistance or working length. If resistance is encountered before WL, go to the next smaller size until WL is achieved (per brochure protocol). _(File: 30/.04 (small canals) · 250-360 rpm)_
   - Step down to smaller sizes if resistance prevents reaching WL (per brochure)
2. **Crown-Down for Larger Canals** — In larger canals, begin with a 40/.04 rotary file to resistance or working length. If resistance is encountered before WL is achieved, move on to smaller-sized instruments until WL is achieved (per brochure protocol). _(File: 40/.04 (larger canals) · 250-360 rpm)_

### Finishing

1. **Recapitulate and Confirm** — Between each rotary V-Blue, recapitulate with a #10 or #15 hand file, irrigate with NaOCl, and confirm apical patency before obturation (per brochure protocol).

## Clinical Tips

- Brochure-verified material: Blue NiTi; brochure-verified speed: 250–360 rpm; length 21/25/31 mm; package 6 pcs per box/blister
- Convex triangle cross-section is explicitly named in brochure body text — described as enhancing cutting action while decreasing rotational friction between blade and dentin
- Files may appear slightly curved out of the package — this is a wire-processing artifact, not a defect; finger-straightening is optional (per brochure Selling Point section)
- Brochure spec table extracted text is partial; the visible row ("15 | 15/.04 | 15/.06") plus the 6 colored handle stops in the brochure image (white/yellow/red/blue/green/black for ISO 15/20/25/30/35/40) imply a full 12-file matrix (6 tip sizes × 2 tapers each)
- Torque values are NOT specified in the V-Blue brochure — verify motor torque settings before clinical use
- Crown-down protocol with step-down on resistance: small canals start at 30/.04, large canals start at 40/.04 (per brochure Protocol for Use)
- Recapitulate with #10 or #15 hand file between rotary files to maintain glide path and aid NaOCl irrigation (per brochure)

## Warnings

- Single-use; discard after each canal (per Perfect Dental IFU family precautions — V-Blue brochure has no dedicated IFU section)
- Do not autoclave above 200 °C including drying phase (per Perfect Dental IFU family precautions — V-Blue brochure has no dedicated IFU section)
- 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 — V-Blue brochure has no dedicated IFU section)
- Inspect each file for distortion, unwinding, corrosion, or damaged edges before use (per Perfect Dental IFU family precautions — V-Blue brochure has no dedicated IFU section)
- Use minimal apical pressure; never force the file (per Perfect Dental IFU family precautions — V-Blue brochure has no dedicated IFU section)
- Contraindicated in patients with nickel allergy (per IFU)

## Contraindications

- patients with known nickel allergy (per IFU)
