## Protocol

### Glide Path

1. **Hand-File Scout + NaOCl Irrigation** — Use K-files to reach working length and irrigate thoroughly with sodium hypochlorite (per brochure operation procedure, step 1).
   - Irrigate thoroughly with NaOCl between files (per brochure)
2. **Mechanical Orifice Opening with Starter** — Brochure sequence diagram includes a Starter file (Starter tip / .12 taper, no ISO color code) between the K-file scout and the P1/P2 glide-path step. The brochure text does not detail Starter usage; treat as an optional orifice opener at 350 rpm / 3.0 N·cm (per brochure spec card and sequence diagram). _(File: Starter (Starter/.12) · 350 rpm · 3.0 N·cm)_
3. **Glide Path with P1 → P2 (if curved)** — For curved canals, prepare a glide path with P1 (16/.02, white) then P2 (19/.02, yellow) at 350 rpm / 3.0 N·cm before introducing the shaping files (per brochure operation procedure, step 2 and spec card). _(File: P1 then P2 · 350 rpm · 3.0 N·cm)_
   - Brochure language: "Glide path preparation with P1, P2 for curved canal if necessary" — P1/P2 are optional for straight canals (per brochure)

### Shaping

1. **Dentin Removal and Shaping** — Use G1 (20/.04, yellow) followed by G2 (25/.06, red) for routine shaping at 350 rpm and 3.0 N·cm torque (per brochure spec card). EDTA is recommended during treatment for smear-layer management (per brochure). _(File: G1 then G2 · 350 rpm · 3.0 N·cm · Continuous rotation)_
   - Brochure cites three cross-section advantages: improved performance, lower tendency to break, and more thorough debris removal (per brochure marketing claim — geometry name not given, not independently verified)
   - Incremental thread spacing is described as supporting maximum cutting ability (per brochure image caption)
   - Non-cutting tip is explicitly described in the brochure ("Non-cutting tip" image caption) as guiding the instrument, reducing step penetration, and helping preserve the original canal shape
2. **Large Canal Finishing** — For wider canals, finish with G3 (35/.04, green) at the same 350 rpm / 3.0 N·cm settings (per brochure operation procedure step 4 and spec card). _(File: G3 · 350 rpm · 3.0 N·cm)_

### Finishing

1. **Irrigation Finish** — EDTA irrigation is recommended during the shaping sequence (per brochure). Confirm apical patency with a small hand file and finalize the cleaning protocol before obturation.

## Clinical Tips

- Full brochure spec card (image): Starter (—/.12), P1 (16/.02, white), P2 (19/.02, yellow), G1 (20/.04, yellow), G2 (25/.06, red), G3 (35/.04, green) — all rated 3.0 N·cm at 350 rpm (per brochure file table)
- MG3 is the conventional NiTi version of Perfect Dental's MG-line concept; for heat-treated flexibility consider MG3 Blue (per brochure family positioning)
- Length range 21/25/31 mm covers most posterior anatomy (per brochure)
- Use torque-controlled endodontic motor; brand cites the Perfect Endo Motor series as compatible (per MG3 Blue brochure family reference)

## Warnings

- Brochure does not include a stand-alone IFU section; warnings here mirror the Perfect Dental IFU family pattern (RC, TS4, PX Wave, TF4, TG6) and are explicitly 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)
- Use minimal apical pressure; never force the file (per Perfect Dental IFU family precautions)
- Inspect each file before use for distortion, unwinding, corrosion, or damaged edges (per Perfect Dental IFU family precautions)
- Patients with nickel allergy: contraindicated (per Perfect Dental IFU family precautions)

## Contraindications

- patients with known nickel allergy (per IFU)
- severely curved canals — consider heat-treated alternatives (general guidance)

## FAQ

**What alloy is MG3 made from?**

MG3™ is manufactured from Conventional NiTi.

**How many files are in the MG3 sequence?**

The MG3™ system includes 6 files: Starter, P1, P2, G1, G2, G3.

**What is the MG3 file sequence?**

MG3™ is used in this order: P1 → P2 → Starter → G1 → G2 → G3. Per-file speed, torque and technique are in the protocol section above.

**What motion type does MG3 use?**

MG3™ uses continuous rotation motion.

**What cases is MG3 best for?**

MG3™ is best suited for: value-tier rotary multi-file sequence, general shaping in mild–moderate curvature, practices wanting a structured glide-path → shaper workflow.

**What speed and torque settings are recommended for MG3?**

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