A sterilization log shows a load failed a biological indicator test. What is the FIRST action the dental team should take?
Answer: Immediately recall all items from that load and remove the sterilizer from service
A failed biological indicator requires immediate removal of the sterilizer from service and recall of all items processed since the last passed test.
Which of the following is an example of a critical dental instrument requiring sterilization before each use?
Answer: Surgical extraction forceps that penetrate soft tissue
Critical instruments penetrate soft tissue or bone and must be sterilized between each patient use to prevent infection transmission.
What is the function of a washer-disinfector in the instrument reprocessing workflow?
Answer: It mechanically cleans and thermally disinfects instruments to reduce bioburden before sterilization
A washer-disinfector uses heat and detergent to mechanically clean and thermally disinfect instruments, reducing bioburden as a precursor to sterilization.
Dry heat sterilization at 320°F (160°C) typically requires how long for a full cycle?
Answer: 1–2 hours
Dry heat sterilization requires longer exposure times than steam—typically 1 to 2 hours at 320°F (160°C)—because dry heat is less efficient at killing microorganisms than moist heat.
Which packaging material is appropriate for use with unsaturated chemical vapor (Chemiclave) sterilization?
Answer: Paper/plastic peel pouches designed for chemical vapor
Paper/plastic peel pouches that allow chemical vapor penetration are the appropriate packaging for unsaturated chemical vapor sterilization.
What does 'event-related sterility' mean for packaged instruments?
Answer: Sterility is maintained indefinitely as long as the package remains intact and undamaged
Event-related sterility means a properly packaged and stored instrument remains sterile until an event compromises the package (e.g., torn seal, moisture damage), not based on a fixed expiration date.
A dental assistant is using an ultrasonic cleaner. Which personal protective equipment (PPE) is MOST important to wear when removing instruments from the unit?
Answer: Heavy-duty utility gloves, eye protection, and a mask
Heavy-duty utility gloves, eye protection, and a mask are required because ultrasonic cleaners can aerosolize contaminated particles when the lid is opened.
