Clinical Tip

E-Flex Gold is a nine-file gold heat-treated controlled-memory rotary family that brings its own orifice opener (17/.08) and glider (19/.02), running at a uniform 350 RPM / 2.5 Ncm across the shaping files. Reciproc blue shapes with one reciprocating file at 150°/30°, is pre-bendable, and its data lists severe curvature, calcified canals and retreatment among its uses. Choose E-Flex Gold for an integrated rotary workflow in one family, Reciproc blue for single-file reciprocation in demanding anatomy.
