ProTaper Gold®
Variable taper design with progressive engagement
| File | Tip | Taper | Speed rpm | Torque Ncm |
|---|---|---|---|---|
| 0.19 | 3.5-19% | 300 | 5.2 | |
| 0.18 | 2-11% | 300 | 5.2 | |
| 0.20 | 4-11.5% | 300 | 1.5 | |
| 0.20 | 7% | 300 | 1.5 | |
| 0.25 | 8% | 300 | 3.1 | |
| 0.30 | 9% | 300 | 3.1 | |
| 0.40 | 6% | 300 | 3.1 | |
| 0.50 | 5% | 300 | 3.1 |
Speed range: 250-350 RPM (300 RPM recommended)
Gold heat treatment may provide improved cyclic fatigue resistance vs ProTaper Universal — manufacturer reports ~2.6x avg (internal lab data, not independent clinical validation)
Manufacturer reports ~24% increased flexibility vs ProTaper Universal (internal lab data) — independent bench studies confirm directional improvement (Hieawy 2015, PMID 26426295)
Shorter 11mm handle allows improved accessibility to posterior teeth
Same exact geometries as ProTaper Universal with advanced metallurgy
Convex triangular cross-section and progressive taper enhance cutting action while decreasing rotational friction
Non-cutting tip design with small flat area enhances ability to navigate through soft tissue and debris
Use Shaping files (S1, S2, SX) with brushing action on withdrawal stroke
Use Finishing files (F1-F5) with non-brushing action — follow canal passively to WL
Files may appear slightly curved — this is normal, not a defect
File will follow canal anatomy once inside
Sequence is the same regardless of canal length, diameter, or curvature
Always use minimal apical pressure — never force files
For optimal usage, torque control devices are recommended
Obturation Techniques
Single cone, warm vertical, carrier-based & lateral compaction
