The least transportation was found in the NiTi and piston groups. The handpiece with a #25 H file demonstrated a good centering ability, similar to the NiTi file, which enabled speedy preparation. The time required for preparation between the piston or NiTi group and the manual group was statistically different. No significant difference was observed between the piston and NiTi groups (P .05). We concluded that the newly designed handpiece achieved efficient canal preparation and negotiation. The handpiece could avoid endodonti
