Instrument Decontamination And Sterilization

1. A defined decontamination workflow is in place: the instrument processing area has separate dirty, cleaning, and clean/sterile zones with clear directional flow from soiled to sterile


Photo Comment

2. Used instruments are transported to the decontamination room in a closed, puncture-resistant container immediately after use


Photo Comment

3. Instruments are cleaned by the appropriate method (automated washer-disinfector or ultrasonic cleaner with manual pre-clean) before sterilization; hand-scrubbing alone is not used


Photo Comment

4. Cleaned instruments are inspected for residual debris and damage before packaging


Photo Comment

5. Instruments are packaged in appropriate pouches or wraps before sterilization, with a chemical indicator inside each package


Photo Comment

6. Instrument packs are labeled with the sterilizer cycle reference or batch number, enabling traceability


Photo Comment

7. The sterilizer is validated, maintained per the manufacturer's schedule, and a current maintenance record is held


Photo Comment

8. A biological indicator (spore test) is used to verify sterilizer efficacy at the applicable frequency per practice protocol


Photo Comment

9. Sterilizer cycle logs are maintained for each cycle run, including date, cycle parameters, and pass/fail result


Photo Comment

10. Sterile instrument packs are inspected for integrity before use; packs with compromised seals, tears, or punctures are not used and are returned for reprocessing


Photo Comment

11. Sterilized instruments are stored in a clean, dry, covered environment with protection from contamination, and stock is rotated on a first-in-first-out basis


Photo Comment

12. Single-use items are not reused; packaging indicating single use (the figure-2 symbol) is identifiable by all relevant staff


Photo Comment
Dental Unit Waterlines (DUWL)

7. Bottle reservoirs (where applicable) are emptied, cleaned, and disinfected at the frequency specified by the manufacturer or practice protocol


Photo Comment
Operatory And Clinical Surface Management

1. A written schedule for clinical contact surface management is in place, specifying which surfaces are barrier-protected and which are decontaminated between patients
