Ultrasonic cleaners are a valued aid to instrument cleaning in many general dental practices. This article reviews the different ways their cleaning efficiency has been assessed. It is recommended that burs and files should be cleaned ultrasonically before first use. Prophylaxis cups are not sufficiently decontaminated by ultrasonic cleaning and therefore should be discarded after use. Although instruments are visibly clean after ultrasonic cleaning and generally clean when viewed with an electron microscope, ultrasound alone is insufficient for sterilisation. Further avenues of research have been highlighted.
在许多普通牙科诊所中，超声波清洗器是器械清洁的重要辅助工具。本文回顾了评估其清洗效率的不同方法。建议车针和锉刀在首次使用前应进行超声清洗。预防性杯通过超声清洗不能充分去污，因此使用后应丢弃。尽管器械在超声清洗后肉眼可见是干净的，并且在电子显微镜下观察通常也是干净的，但仅靠超声不足以进行灭菌。文中还强调了进一步的研究途径。
