Rotary motion using OneShape single file
Reciprocating motion using WaveOne Gold single file
File size 25 with a taper of 0.06 was mounted to a 6:1 speed-reduction headpiece powered by X Smart Plus endomotor (Dentsply Maillefer, Ballaigues, Switzerland). The speed and torque were set to 400 rpm and 1 N.cm torque, respectively. In a picking motion without pressure, mechanical preparation began with the first RC two-thirds followed by the next 3 mm followed by the full WL.
A Primary file size 25 a taper of 0.07 was installed to pre-programmed reciprocation angles and speed for the WaveOne system handpiece of an endomotor (X Smart Plus endomotor (Dentsply Maillefer, Ballaigues, Switzerland). After ensuring a passive fit of the hand file along the predetermined WL, the RC coronal two-thirds was initially instrumented then followed by the full WL.
