## Protocol

### Glide Path

1. **Scout Canal with K-files** — Create straight-line access. Negotiate all root canals to their terminus with stainless steel Lexicon K-Files, in the presence of ProLube root canal conditioner. Establish patency by taking a #10 K-File past the canal terminus and at least a #15 K-File to the terminus.
   - Pre-curve K-files for curved canals
   - Use ProLube (EDTA-based conditioner) during negotiation per DFU
   - Verify smooth, reproducible glide path to at least loose #15
2. **Establish Glide Path** — Ensure a reproducible glide path to working length using #10 and #15 K-files (Lexicon or equivalent). The glide path must be confirmed before using any rotary Vortex Blue file.
   - #10 K-file must pass terminus; #15 K-file must reach terminus
   - Use lubricant (EDTA gel) during negotiation
   - Irrigate with NaOCl between hand file passes
   - ⚠ Do not use rotary files without confirmed glide path
   - ⚠ Do not force hand files apically

### Shaping

1. **Crown-Down: Small Canals** — For small canals, start with 30/.04 and advance toward the working length. If resistance is met, crown-down to smaller files (25/.04, 20/.04, 15/.04) to establish a path, then return to the larger file. Recapitulate with #10 or #15 K-file between each rotary file. _(File: 30/.04 (start) → crown-down as needed · 500 RPM · Continuous rotation)_
   - Use minimal apical pressure — let the file do the work
   - Recapitulate with #10 or #15 K-file between each file
   - Irrigate with NaOCl between each file change
   - Take any file to length only one time and for no more than 1 second
   - Inspect files for distortion or wear between uses
   - ⚠ Do not force files — if resistance is met, crown-down to a smaller size
   - ⚠ Do not choose overly large files for the canal anatomy
2. **Crown-Down: Large Canals** — For large canals, start with 40/.04 and advance toward the working length. If resistance is met, crown-down to smaller files (30/.04, 25/.04) to establish a path, then return to the larger file. Recapitulate with #10 or #15 K-file between each rotary file. _(File: 40/.04 (start) → crown-down as needed · 500 RPM · Continuous rotation)_
   - Larger starting file removes more coronal dentin for improved access
   - Follow the same crown-down principle as small canals
   - Always recapitulate with hand files between rotary passes

### Finishing

1. **Taper Selection Guidance** — Use .06 taper files for the coronal portion of canals with mild to moderate curvatures. Use .04 taper files past mid-root in canals with moderate to severe curvature. The .04 taper provides greater flexibility in curved regions while the .06 taper provides more efficient coronal enlargement.
   - .06 taper (25/.06 or 30/.06) for coronal portions of mild/moderate curvatures
   - .04 taper for mid-root to apical in moderate/severe curvatures
   - Full range available: 15-50 in both .04 and .06 tapers
   - Select taper based on canal anatomy at each level
2. **Obturation** — When using centrally condensed warm gutta-percha techniques such as Vortex obturators, rely on size verifiers to determine proper fit and length control. A Vortex obturator the same tip/taper as the size verifier taken to working length can be used to obturate the canal.
   - Use Vortex Size Verifiers to confirm obturator fit and length control (per DFU)
   - Matching Vortex obturators available for carrier-based obturation (per DFU)
   - Vortex Blue Conform Fit GP points also available (per product page)
   - Verify tug-back with master cone before obturation
   - Standard irrigation protocol

## Clinical Tips

- All files use 500 RPM — no speed changes between files
- Crown-down technique: start with larger file, reduce size if resistance is met
- .04 taper recommended for moderate to severe curvatures past mid-root
- .06 taper for coronal portions of mild to moderate curvatures
- Recapitulate with #10 or #15 K-file between each rotary file
- Non-cutting tip design reduces risk of ledging and perforation
- Patented variable helical angle design (same as ProFile Vortex) — enhances cutting efficiency and reduces thread-in
- Convex triangular cross-section enhances cutting action while decreasing rotational friction
- Full range available: sizes 15-50 in both .04 and .06 tapers (16 SKUs total)
- Matching Vortex obturators, Conform Fit GP points, and paper points available
- Manufacturer reports min 65% improvement in cyclic fatigue over M-Wire NiTi (bench data, per current brochure)
- Manufacturer reports min 99% improvement over standard NiTi, up to 353% (bench data, per current product page)
- Manufacturer reports at least 42% higher peak torque vs M-Wire NiTi, up to 126% (bench data)
- Files may appear slightly curved from heat treatment — this is not a defect; files follow canal anatomy once inside

## Warnings

- Single use only — provided sterile, cannot be resterilized or reused
- Contains nickel — do not use on patients with nickel allergy
- Always use minimal apical pressure — do not force files
- Take any file to length only one time and for no more than 1 second
- Exercise caution in the apical area and around significant curvatures
- Inspect files for distortion or wear between each file use
- Do not choose overly large files for the canal anatomy
- If a file does not easily progress, remove and use a smaller file first
