The aim of this study is to consider the effectiveness of a small sample of dishwashers (DW) compared to washer-disinfectors (WD) for cleaning dental instruments prior to sterilisation. Processing instruments in the context of this article means cleaning and disinfecting the instruments.
A number of tests were carried out on three domestic dishwashers and two instrument washer-disinfectors. These tests included: visual test; soil test; residual protein test; and, the TVC of the final rinse water.
The washer-disinfectors (one bench-top and one under-bench) passed all the tests. The results indicate that the instruments cleaned in the dishwashers were visibly clean and dishwashers passed the TOSI soil test. There was residual protein on some of the instruments cleaned in the all of the dishwashers and the final rinse water did not comply with standard ISO 15883.
Dishwashers are not effective for cleaning instruments and they do not disinfect the instruments either. They cannot be validated and there is no record available outlining the parameters of the process. Dishwashers are not designed by manufactures for processing dental instruments prior to sterilisation. The authors do not recommend the use of dishwashers in dental clinical practice.
本研究旨在比较少量洗碗机（DW）与清洗消毒机（WD）在对牙科器械进行灭菌前清洁的有效性。本文中对器械的处理是指对器械进行清洁和消毒。
对三台家用洗碗机和两台器械清洗消毒机进行了多项测试。这些测试包括：目视检查；污垢测试；残留蛋白质测试；以及最终冲洗水的总活菌数（TVC）测试。
清洗消毒机（一台台式和一台台下式）通过了所有测试。结果表明，在洗碗机中清洗的器械肉眼可见是干净的，并且洗碗机通过了TOSI污垢测试。在所有洗碗机中清洗的部分器械上有残留蛋白质，并且最终冲洗水不符合ISO 15883标准。
洗碗机对器械清洁无效，也不能对器械进行消毒。它们无法得到验证，并且没有记录概述该过程的参数。制造商并非为在牙科器械灭菌前对其进行处理而设计洗碗机。作者不建议在牙科临床实践中使用洗碗机。
