Conclusion
This single center study investigated the CFUs reduction on contaminated FEs without a working channel after UV-C light disinfection compared to the current golden standard reprocessing process using the EWD. The findings of this study show that there is no difference in CFU reduction between UV-C light disinfection compared to the current reprocessing process with the EWD. UV-C light disinfection could be a good alternative for disinfecting FEs without a working channel. However, the effectiveness of UV-C light disinfection depends on the diligence van the pre-cleaning process.
