Reciprocating Root Canal Shaping with Just 3 Files A complete clinical walkthrough of the R-One Mini Kit by Fanta (R1 Mini) — a minimal 3-file reciprocating sequence (1 + 2) designed for fast, safe and minimally invasive root canal shaping, even in narrow and severely curved canals. In this lecture, Dr. Francesca Cerutti breaks down the file design, the metallurgy behind each instrument, and the reciprocation kinematics — then demonstrates the full protocol on multiple real cases, including molars, premolars, retreatments and complex anatomies (MB2 / DB2, confluences, 90° curvatures). What's covered File sequence & settings ▸ Early Coronal Flare — 19/.05 · double-S · continuous rotation 250 rpm (coronal third only) ▸ 1st Shaper — 17/.04 · AF-L wire · reciprocation 150° CCW / 30° CW ▸ 2nd Shaper — 25/.06 · AF-R wire · reciprocation 150° CCW / 30° CW ⚠ Always perform apical gauging after the 25/.06 to confirm final apical diameter.
