Ultrasonic instruments for endodontic, endo-restorative, and microrestorative procedures are underutilized by restorative dentists. These ultrasonic instruments are useful with traditional visualization (unaided vision or loupes). However, their true worth can best be appreciated in conjunction with microscopic visualization. It is imperative that the reader understand that some of the utilizations described in this article are not recommended unless accompanied by the operating microscope and some level of training.
修复牙医对用于牙髓病治疗、牙髓修复和微修复手术的超声器械利用不足。这些超声器械在传统可视化（裸眼或头戴放大镜）下很有用。然而，它们的真正价值在结合显微镜可视化时才能得到最佳体现。读者必须明白，除非有手术显微镜和一定程度的培训，否则本文所述的一些用途是不推荐的。
