Clinical Tip
NIC positions U-Series as its alternative for ProTaper users — matching SX–F5 sizing at one 400 RPM / 3.0 Ncm setting, but documented only by the manufacturer's catalog. Choose ProTaper Gold for the extensively studied original with published variable-taper design, IFU-defined reuse limits, and independent performance data.
