## Protocol

### Glide Path

1. **Hand-File Scout** — Use an ISO 010 K-file with 2–3 mm thrusts to reach working length one or more times. Irrigate thoroughly with sodium hypochlorite (per IFU step 3).
2. **Expand with ISO 015** — Continue with the ISO 015 K-file to expand the canal channel and reconfirm working length (per IFU step 4).
3. **Mechanical Glide Path with V1 (V0 optional)** — Per IFU step 5: "Use product 018 02 to clear the root canal channel using the action of step ③ until the working length is reached (if necessary, use product 019 04 file to expand the root canal channel opening)." — V1 (18/.02) is the primary glide-path file; V0 (19/.04, 19 mm) is an optional orifice-opening adjunct. _(File: V1 18/.02 (optional pre-step: V0 19/.04) · 250-350 rpm · 3.0 N·cm)_

### Shaping

1. **Primary Shaping with V2 + T1** — Per IFU step 6: "Use products 020 04 & 020 07 to shape the root canal channel until the working length is reached." — V2 (20/.04) and T1 (20/.07) are the primary shaping files used together (or sequentially) to working length. _(File: V2 20/.04 + T1 20/.07 · 250-350 rpm · 1.5 N·cm)_
2. **K-File Gauge Check at ISO 020** — Check the canal with an ISO 020 K-file at working length. If the compactness is appropriate, shaping is complete; if loose, continue with a larger model file (per IFU step 7).
3. **Sequential Escalation with T2 → T5 (only if K20 gauge is loose)** — Per IFU step 7: "If it is loose or not tight, it is recommended to continue using a larger model of this product to shape the root canal channel. Use it sequentially from small to large, and check with a corresponding size K file until the shaping of the root canal channel is completed." — escalation files T2 (25/.08, 2.5 N·cm), T3 (30/.09, 2.5 N·cm), T4 (40/.06, 2.5 N·cm), T5 (50/.05, 2.5 N·cm) at 250–350 rpm. _(File: T2 → T3 → T4 → T5 (only as needed) · 250-350 rpm · 2.5 N·cm)_
   - Always confirm with a matching K-file gauge between escalation steps (per IFU step 7)
   - Stop at the largest file that achieves a tight gauge fit; further escalation risks over-shaping (general guidance based on IFU sequence)

### Finishing

1. **Confirm Final Shape** — Confirm the final canal shape with the matching K-file, irrigate, and dry before obturation.

## Clinical Tips

- TG6 is an 8-instrument sequence (per IFU spec table): V0 19/.04 (optional orifice opener, 19 mm), V1 18/.02 (glide path), V2 20/.04 and T1 20/.07 (primary shapers used together per IFU step 6), T2 25/.08 / T3 30/.09 / T4 40/.06 / T5 50/.05 (escalation files used sequentially only if the ISO 020 K-file gauge is loose per IFU step 7)
- K-file gauge with ISO 020 between primary shaping (V2+T1) and any escalation is required per IFU step 7
- T3 30/.09 is the largest taper in the set — verify motor torque headroom before use (general guidance)
- Cross-section geometry is not specified by name in the IFU text

## Warnings

- Single-use; discard after each canal (per IFU section 3)
- Do not autoclave above 200 °C including drying phase (per IFU precautions)
- 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)

## FAQ

**What alloy is TG6 made from?**

TG6™ is manufactured from NiTi with conventional heat treatment.

**How many files are in the TG6 sequence?**

The TG6™ system includes 8 files: V0 19/.04, V1 18/.02, V2 20/.04, T1 20/.07, T2 25/.08, T3 30/.09, T4 40/.06, T5 50/.05.

**What is the TG6 file sequence?**

TG6™ is used in this order: V1 18/.02 → V0 19/.04 → V2 20/.04 → T1 20/.07 → T2 25/.08 → T3 30/.09 → T4 40/.06 → T5 50/.05. Per-file speed, torque and technique are in the protocol section above.

**What motion type does TG6 use?**

TG6™ uses continuous rotation motion.

**What cases is TG6 best for?**

TG6™ is best suited for: extended sequence with built-in K-file gauge checks, wider canals where T4/T5 finishing matters, practices wanting a single-brand glide path through finishing.

**What speed and torque settings are recommended for TG6?**

Recommended settings: 250-350 RPM and 3.0 / 1.5 / 2.5 Ncm across the file sequence (refer to official DFU for full per-file parameters).
