Clinical Tip
Reciproc blue shapes with one reciprocating file at 150°/30° and its data lists severe curvature, calcified canals and retreatment among its uses; the blue treatment makes the file pre-bendable. ZenFlex is a continuous-rotation controlled-memory system at 500 RPM whose 1 mm maximum flute diameter is aimed at conservative access, with torque set per taper and size. Choose Reciproc blue when a single pre-bendable file in reciprocation suits the anatomy, ZenFlex when you prefer graduated rotary shaping.
