Clinical Tip

Two two-file-minded conservative systems. ESX shapes with a 15/.05 Expeditor and one .04 finishing file (25–55) in electropolished NiTi at 500–600 RPM; TruNatomy shapes with heat-treated regressive-taper files at 500 RPM / 1.5 Ncm and a 0.8 mm maximum flute diameter, pre-bendable for restricted access. Choose ESX for adaptive finishing-size selection, TruNatomy for the heat-treated slim profile.
