| Abstract: | Objective To understand the failure incidence of NiTi rotary instruments in clinical application, and serve for safe application in clinic. Methods 48 new NiTi rotary instruments were received from warehouse gradually. The first use time, use frequency, the time and length of broken, deformation of NiTi rotary instruments were recorded carefully; Root canal curvature was checked with X ray. Results It was safe to use NiTi rotary instruments 13 times repeatedly; It was broken 1 time of SX, S1, F2, 6 times of... |
