We evaluated the mechanical properties and torque/force generated during canal shaping by four NiTi files with innovative designs. Each of 52 TruNatomy Prime, XP-endo Shaper, Spring Endo unheated finish (Spring Endo), heated H) were subjected to bending, buckling, cyclic fatigue, torsional resistance tests (n = 10 per file type). Canal was simulated J-shaped resin blocks 10). Phase transformati...

Background: This study was conducted to analyse the effect of different enzymes and selenium on production performance slaughter parameters Ross (308) broilers production. Method: There were four groups in this experiment, two them control test groups. All had same number one-day-old chickens (20250), moved day. 100 selected randomly for future analyses. The group fed with standard commercial d...
