• Enhanced Stiffness: Specially treated stainless steel provides superior bucking resistance compared to traditional files.

• Non-Cutting Tip: Features a "safety" tip that helps the file follow the natural curvature of the canal, reducing the risk of ledging or perforation.

• High Temperature Resistance: Rated for sterilization up to 200°C / 390°F.

• Color-Coded Handles: Ergonomic handles follow ISO color standards for easy size identification (e.g., Purple for size 10).

• Calibration Rings: The handles often feature depth marks to assist in maintaining working length.

Roydent C-Files are specialized endodontic hand instruments designed specifically for navigating calcified or highly curved root canals. Unlike standard K-Files, C-Files are engineered with a unique heat-tempering process that makes them significantly stiffer. This stiffness allows the clinician to apply necessary apical pressure to penetrate blockages without the file bending or buckling prematurely.

• Quantity: Typically sold in packs of 6 files.

• Container: Clear plastic blister/case with a sliding or snap-off lid.

• Labeling: Includes the CE mark, manufacturer details (United Dental Manufacturers, Inc.), and clear size/length indicators.

• Preparation: Clean and sterilize the files before the first use (unless labeled pre-sterile).

• Access: Establish straight-line access to the canal orifice.

• Exploration: Use a "watch-winding" motion (slight clockwise and counter-clockwise rotation) with gentle apical pressure to negotiate calcified areas.

• Lubrication: Always use with an endodontic lubricant or chelating agent (like EDTA) to facilitate movement and debris removal.

• Irrigation: Irrigate the canal frequently between file sizes to remove dentinal shavings.

• Disposal: These are precision instruments; inspect for unwinding or fatigue after each use and discard if any deformation is visible.

• Manufacturer: Manufactured for United Dental Manufacturers, Inc. (Johnson City, TN).

• Regulatory: Features the CE mark, indicating compliance with European health, safety, and environmental protection standards.

• Storage: Store in a cool, dry place away from corrosive chemicals.
