The surface of auxiliary gutta-percha cones after cutting with different methods was evaluated. The tips of gutta-percha cones size fine were cut off using scissors, a razor blade against a glass slab, a razor blade combined with a calibrator, or a razor blade/calibrator followed by a further cutting with a razor blade against a glass slab. Samples were examined under scanning electron microscopy. Cutting with scissors and razor blade/calibrator produced significant irregularities in the cone surface. Cutting with razor blades against a glass slab, with or without previous use of a calibrator, allowed the development of a smooth gutta-percha cone surface.
