Protective Clothing and Mask Quiz

Sterilization is crucial in dental practices to prevent infection transmission, achieved through steam under pressure (autoclaving), dry heat, or heat/chemical vapor.

Semicritical instruments, such as amalgam condensers, syringes, mirrors, and radiography accessories, contact oral tissues and must be sterilized after each use or high-level disinfected.

Critical instruments, like forceps and scalpels, penetrate soft tissues and bone and must be sterilized.

Noncritical instruments, which touch only intact skin, may be reprocessed between patients using intermediate- or low-level disinfection.

Contaminated sharps, such as needles, scalpel blades, orthodontic wires, and glass, should be placed in a sharps container immediately after use, as per OSHA, CDC, and EPA regulations.

Proper processing of contaminated dental instruments involves six steps: transport, cleaning, packing, sterilization, storage, and delivery.

Instruments that cannot be cleaned immediately after procedures should be placed in a holding solution to prevent drying. A holding solution is a non-corrosive, non-staining, low-cost liquid used to decrease infectious microbes and loosen debris.

Precleaning methods include hand scrubbing, ultrasonic cleaning, and instrument washing machine. Hand scrubbing is unfavorable due to the risk of injury and direct contact with contaminated instruments.

Ultrasonic cleaning, which uses sound waves to form bubbles for mechanical cleaning, is recommended instead of hand scrubbing.

Instruments must be packaged before sterilization to protect them from contamination by aerosols, dust, or contact with nonsterile surfaces.

Sterilization monitoring is necessary to ensure proper sterilization. Three forms of sterilization monitoring include physical, biological, and chemical methods. Physical monitoring involves checking sterilizer gauges and recording temperatures, pressures, and exposure times. Chemical monitoring uses heat-sensitive chemicals that change color when exposed to certain conditions. Process indicators identify packaged instruments as processed or not, while process integrators measure the duration and pressure of the sterilization process.
