Clinical Tip
ProTaper Gold shapes through a progressive-taper SX–F5 sequence in gold-treated wire at 300 RPM; ESX reduces shaping to an Expeditor plus one .04 finishing file in electropolished conventional NiTi at 500–600 RPM, with the Booster Tip intended to reduce ledging. Choose ProTaper Gold for graduated shaping with independent evidence, ESX for a minimally invasive two-file workflow.
