• Ultra-thin S Section: An upgraded cross-sectional design that reduces the core mass, allowing for greater flexibility and more space for debris evacuation.

• Positive Cutting Angle: Designed for high cutting efficiency, reducing the time required for canal preparation.

• Superior Flexibility: The heat-activated metallurgy allows the file to navigate sharp curves while significantly resisting cyclic fatigue.

• Minimal Invasive Design: Follows the MIE (Minimally Invasive Endodontics) concept, preserving more natural tooth structure during cleaning and shaping.

The Kinetic Rainbow S is a premium, multi-colored heat-activated Nickel-Titanium (NiTi) rotary file. It is specifically engineered with an upgraded "Ultra-thin S Section" to provide maximum cutting efficiency while maintaining extreme flexibility. The "Rainbow" finish indicates a specialized thermal treatment that optimizes the metal's molecular structure for navigating complex canal curvatures with minimal resistance.

• Material: Heat-Treated "Rainbow" Nickel-Titanium Alloy.

• Cross-Section: S-shaped (Ultra-thin).

• Taper/Sizes: Commonly available in standard ISO sizes (e.g., 25/04, 25/06) with color-coded bands.

• Length: 21mm, 25mm, and 31mm.

• Rotation: Constant clockwise rotation.

• Recommended Speed: 250–350 RPM.

• Recommended Torque: 1.5–3.0 N·cm.

• Blister Pack: Contains 6 files per pack.

• Options: Available in assorted packs (full sequence) or individual size packs.

• Glide Path: Always establish a glide path with a #10 manual file before introducing rotary instruments.

• Lubrication: Use EDTA lubricant and irrigate with Sodium Hypochlorite (NaOCl) throughout the process.

• Technique: Use a gentle "picking" motion. Advance the file 1–2mm, then withdraw to clean the flutes.

• Inspection: Regularly inspect the "S" section for any signs of unwinding or metal fatigue.

• Sterilization: Provided non-sterile. Must be autoclaved at 134°C before clinical use.

• Safety: The ultra-thin design is highly efficient but requires careful torque management to prevent instrument separation.

• Single-Use: Highly recommended for single-patient use to ensure the integrity of the thin S-section.

• Standard Coverage: Guaranteed against manufacturing defects and material flaws upon arrival.

• Clinical Exclusion: Warranty does not cover breakage caused by excessive torque, improper RPM, or use in calcified canals without a proper glide path.
