Nickel-Titanium instruments have become widely used in the endodontic treatment. However, their unexpected separation was a serious concern in endodontics. To date, no scientific methods have been developed to evaluate the functional lifespan of Ni-Ti instruments. In this study, we used resonance frequency analysis to nondestructively detect the fatigue life of Ni-Ti instruments to determine the feasibility of this technique for use in the clinic.
镍钛合金根管锉已经广泛的使用在牙髓病的治疗上，但其无预警的断裂也是令牙医师关心的问题，之前并无一科学性的方法来评估镍钛合金根管锉的寿命，而本研究室利用自然频率的分析方式对镍钛合金根管锉做非破坏性的疲劳检测，确定此方式可行且在临床上有应用的价值。
