Numerical simulation and experimentation of endodontic file using Taguchi DoE

The endodontic file is a tapered, needle shape body used for the preparation of curved human root canals. During preparation, process files get failed due to locking action offered by canal wall. present study aimed find fatigue life at 23°, 33° and 43° curvature angles. Four brands were selected viz. Hyplex CM, Pro-Taper Next, Hero Shaper, Pro-File Vortex. strain analysis done using ANSYS showed that CM gives highest Therefore, was DoE Taguchi Optimization study. Each experimental reading conducted on X Smart Plus setup under purely rotary combined reciprocating-rotary motion, 500 rpm, 600 rpm 700 given maximum 23° angle speed rotation. But if motion rotary-reciprocating, reduces. ANNOVA P -value significance F are very small, which represented regression model effective.
