Description
Summary:[Display omitted] •Development of new sterilization techniques for dental instruments using an RVR.•RVR can completely sterilize the dental instruments under 10 min.•In particular, RVR effectively sterilizes packed instruments.•RVR sterilization is better than UV as it produces a high concentration of ROS. Dental instruments such as dental burs, endodontic files, scalers, and dental vacuum tips require complete sterilization to protect patients from infection. Generally, these instruments are sterilized by autoclaving or using ethylene oxide gas. However, these sterilization methods require a long time, high energy, and the production of hazardous waste. Therefore, a quick, low-energy, and high-sterilization method that generates no hazardous waste is required in the dental field. A radical vapor reactor (RVR) can sterilize bacteria by producing high concentrations of reactive oxygen species. In this study, we found that RVR can sterilize dental instruments effectively (i.e., under 10 min with green technology), and that packed dental instruments can be completely sterilized in 10 min using RVR treatment. Furthermore, we demonstrated that RVR treatment can meet the sterility assurance level. Thus, we propose the use of RVR technology to perform quick sterilization with a low environmental load.
