Today’s busy dental practices face a serious challenge: to maintain or increase productivity while ensuring that patient safety remains a top priority. At times, these may seem like incompatible goals. Advances in dental processing equipment, however, have empowered practices to develop safer processes while realizing efficiencies and ultimately, saving money.
A cleaning and sterilization process that meets ADA and CDC guidelines is vital to an effective infection control program. Streamlining of this process requires an understanding of proper methods, materials, and devices. Many methods of instrument reprocessing are available. Use of a complete system that encompasses and fulfills all elements that are critical maximizes efficiency and minimizes risks. Closed cassette systems provide a more efficient and safer way to process, sterilize and organize instruments in a dental office – these eliminate manual steps during instrument reprocessing such as hand scrubbing and time-consuming sorting of instruments, thereby improving safety and increasing efficiency.
Care must be taken by the dental healthcare professional to ensure that all instruments are cleaned prior to sterilization, and that this is carried out in a safe manner to avoid injury and puncture wounds. Use of closed-system cassettes reduces the risk to dental healthcare professionals when executing infection control programs. When using ultrasonic cleaners, washers and sterilizers, it is important to always follow the manufacturer’s instructions.
It is also important to consult with the manufacturer of dental instruments and devices as needed to ensure complete sterilization and to avoid damage to these items. Assurance of sterility of instruments and devices can be obtained through the use of one of several tests, and these tests must be performed regularly to ensure that the sterilizer is sterilizing all instruments and devices and that these are safe for use on patients.
Parameters such as time, pressure and temperature vary according to the type of autoclave sterilizer, materials being sterilized and individual models within sterilizer brands. The first step in determining the settings for the sterilizer is to refer to the manufacturer’s instructions. Sterilizers are medical devices, requiring clearance by the Food and Drug Administration before manufacturers may offer them for sale. The FDA requires rigorous testing to ensure an adequate margin of safety in each cycle type described in the instructions. Failing to follow the instructions of the manufacturer is ill advised, since it may result in inadequate sterilization of the instruments or devices in the sterilizer. It is never appropriate to use a household device, such as a toaster oven, for sterilization of dental equipment.
