Schematic representation of the push-out test procedure. (a) The middle part of the endodontic obturator is chosen for the test. (b) Slices (height 1 mm and diameter 0.66 mm) are obtained. (c) The slice is fitted into the aperture of a customized syringe. (d) The plunger of the Instron machine is equipped with an orthodontic wire (0.5 mm in diameter) and aligned with the slice to be tested (P = Instron plunger, O = orthodontic wire, and S = syringe holding the slice).
