RCS Gold rotary files have been designed with the following four concepts in mind:
- Minimally Invasive treatment
- Conversing more dentin
- Maintaining curvature of canals
- Safety of use
The working principle is to create a smooth root canal system while retaining as much dentin as possible. this is achieved trough the thin 4% taper on the files.
To achieve these goals, triangular cross section design has been implemented, along with 4% taper, which improves flexibility around curved canals while conserving dentin.
In addition, the revolutionary non-cutting tip has helped to avoid accidental ledge formation, perforations during cleaning and shaping protocol.
RCS Gold files go through special rigorous heat treatment and polishing technique, which leads to extreme flexibility of the file, while improving resistance to cyclic fatigue, which means the files can be drastically reduce file separation.
