Disinfection and Sterilization Protocols
Following every appointment single-use items, including headrest covers, tray covers, and suction tips, are disposed of and all surfaces are wiped down with Optim 33TB. Optim 33TB is accelerated hydrogen peroxide, a one-minute surface cleaner and intermediate level disinfectant. It is classified as a Tuberculocide, Viricide and Bactericide. Wiped surfaces include countertops, adapters, handpiece holders, all tubing, the patient chair, its control buttons and overhead light handles.
Instruments are first put through an ultrasonic cleaner which helps break down any surface debris. The instrument cassettes are then rinsed and a chemical indicator is placed inside of each one, for every cycle all day long. Next is the sterilization process inside the autoclave. The chemical strips change colour if the autoclave has reached the desired temperature for the appropriate time period. In this way, we are confident that the autoclave is functioning properly for every load put through.
Our office uses two sterilizers to ensure we always have backup. And to further ensure our patients’ safety, both of them are tested daily with self-contained biological indicators (also called spore testing). This happens with the first load every day, and at the end of the cycle the test vial is incubated to determine bacterial growth. No colour change from purple to yellow indicates that there has been no bacterial growth and, therefore, complete sterilization has occurred.
