The ProTaper Gold technology includes a series of “Shaping” and “Finishing” files that create the predictable ProTaper shapes. Developed with proprietary advanced metallurgy, ProTaper Gold rotary files feature the same exact geometries as ProTaper Universal, but offer an increase in flexibility. ProTaper Gold shaping files pre-enlarge canals and are designed to be used with the same familiar outstroke brushing technique. ProTaper Gold finishing files are more flexible so you can shape and finish each canal with a complete system approach.
